Hearing loss has been a problem for as long as humans have been around and because hearing loss affects people’s ability to connect and form relationships with others, hearing devices were quickly developed to help those who could not hear.   Here’s a short history of hearing aids – a brief guide to how we got to where we are today.

Bettie Borton, Au.D. Doctor of Audiology AudiologistPre-electric (Acoustic) Hearing Aids
These ear trumpets captured sound waves, sending them down a tube to the listener’s ear. They were big, bulky, unattractive and, frankly, they didn’t work very well. Of course, these were state-of-the art “hearing aids” for centuries until electricity became available.

Carbon Hearing Aids (1900-1939)
These were the first electric hearing aids. Carbon was used to amplify electric current to boost the volume of sound. However, they were bulky, buzzy and downright ugly, though for those with hearing loss, they were the only choice.

Vacuum Tube Hearing Aids (1921-1952)
Vacuum tubes were used to control the flow of electricity and, as such, they did make hearing aids a little better. However, these boxy devices were usually table-top models about the size of a clock radio, so the user had to carry around a heavy box and plug in to hear what was going on.  There weren’t many controls or features, so these devices amplified all sound. That must have caused more than a few headaches back then. But hearing instruments continued to improve.

Transistors to the Rescue (1952-1970s)
Transistors enabled hearing aids to fit into a smaller shell. The first transistor hearing aids appeared in 1952 – actually, two years prior to the first transistor radios which came along in 1954. Transistor hearing aids were still big and bulky with the electronics in a box carried on the body, with ear phones connected to a tangle of wires. Not very convenient, to say the least.

Researchers shrunk transistor hearing aids over the years, making them small enough to fit behind the ear and even in the ear. However, they were anything but low-profile. They also didn’t come packed with features the way today’s hearing aids do.

Digital Hearing Devices
Today, quality hearing aids use digital technology – circuitry that’s used in computers and cell phones -  and what a difference a few decades and countless hours of research and development have made!
Today’s digital hearing devices are sleek, discreet, fashionable, high-tech and low-maintenance. They can be programmed by an audiologist, to suit your specific hearing needs. Most adjust automatically for changes in volume levels and adapt to background noise. And now, with FM, Infrared, or Bluetooth technology, they can connect to multiple devices such televisions and telephones. Did you know that the new Bluetooth capability will allow you to answer you cell hands free, and route the call through both of your hearing devices?

Your hearing is very important and contributes greatly to a better quality of life, and you should do everything you can to make sure you find the right hearing center for your needs.

Finding the right audiologist can be as easy to answering a few simple questions. First, is there a licensed, board certified and experienced audiologist on staff? Then consider…

1. Is this professional willing to make a referral for a medical evaluation to rule out the need for medical or surgical treatment, if necessary?

2. Will the audiologist communicate effectively with you about hearing aid choices and fitting options, if hearing aids are appropriate for your hearing loss?

3. In determining whether a hearing device is appropriate, will the audiologist speak  to you clearly about your hearing loss, lifestyle, manual dexterity, and budget?

4. Does the hearing center offer a wide range of hearing aid makes and models from various manufacturers?

5. Will you receive assistance and training regarding how to wear and care for your hearing devices , as well as how to adjust to wearing them?

6. Does the hearing center offer lengthy trial periods, warranties, and loss and damage protection?

7. Will they provide follow-up care following your hearing aid fitting, at least every six months?

8. Is the hearing center open at least five days a week, with an audiologist on staff to provide emergency care, or loaner hearing aids if needed?

9. Will you always see the same audiologist when you visit?

If you have answered “Yes” to all of these questions, you can rest assured that you have taken the right steps in finding a reputable dispensing practice. Of course, answering some of these questions may require more research than just exploring online. Call the hearing centers in your area to see how they answer your questions.  Once you find one you are comfortable with, schedule an appointment for an initial consultation and hearing test.

So remember, if you’re looking for the latest and the greatest in hearing loss solutions, visit Doctors Hearing Clinic for more information and counseling. Forget everything Grandpa told you about his hearing aids. Those days and those hearing aids are long gone, thankfully. Today, you can enjoy the sounds of life without a lot of hassles.  Modern digital hearing aids deliver sound quality and ease-of-use in small, attractive devices. Seek a Board certified audiologist to explore the world of high tech hearing devices that are now available – and see for yourself that this is NOT your grandmother’s hearing aid!

Constant Ringing in Your Ears?

If it seems like your ears ring constantly, it’s probably not crickets, your imagination or the economy . . . and you’re not alone. You may have tinnitus, an inner ear ailment that affects between 25 million to 50 million Americans — with about 12 million people experiencing such severe symptoms it affects their daily lives. The good news is treatment, including hearing aids, can offer relief to some from the persistent ringing, buzzing or humming associated with tinnitus, according to the Better Hearing Institute.

Tinnitus can be intermittent or constant. Causes range from ear infections and exposure to extremely loud noises, to underlying health problems like allergies or heart and blood pressure problems. Often, sufferers are unable to pinpoint the cause of their tinnitus. “Tinnitus can have a direct impact on a person’s emotional well being,” says Dr. Sergei Kochkin, BHI’s executive director. “Not only can their hearing be affected but also their ability to sleep or concentrate.”

Tinnitus Treatment, Ringing in the Ears CausesKochkin and Dr. Richard Tyler, professor and editor of The Consumer Handbook on Tinnitus (Auricle Ink, 2008), published a survey of 230 hearing health professionals in the United States and Canada. Their survey found that six out of 10 patients reported some tinnitus relief when using hearing aids and two out of 10 reported major relief. The symptoms of tinnitus “influence basic life functions such as socialization and relaxation,” the duo wrote. “In severe cases it can interfere with the individual’s ability to perform adequately on the job, or contribute to psychological disorders such as depression, suicide ideation, posttraumatic stress disorder, anxiety and anger.”

Although tinnitus is actually common and can cause major life disruptions, the number of sufferers who seek treatment for tinnitus is relatively small. One reason may be that they mistakenly believe their condition is untreatable. Unfortunately, many doctors are also unaware of the latest treatment options, and as a result patients may think they simply have to learn to live with the noise.

“No one should ever ignore persistent tinnitus,” Kochkin says. “Not only is every individual entitled to a chance to regain his or her quality of life, but in rare cases tinnitus also can be a symptom of a more serious health issue that could demand medical intervention. What’s more, nearly everyone with tinnitus has hearing loss as well.”

In a recent large-scale survey of the American hearing impaired population, 39 percent (more than 9 million adult Americans) indicated they had not sought help for their hearing loss specifically because they also had tinnitus. “Research shows that untreated hearing loss has its own negative social, psychological, cognitive and health effects on the individual suffering from it,” Kochkin adds. “So those with both untreated tinnitus and untreated hearing loss suffers an even more diminished quality of life than individuals with just tinnitus or just hearing loss alone.”

While hearing aids are not a cure for tinnitus, they may be able to help tinnitus patients by:

1. Improving communication and reducing stress, which makes it easier to cope with the condition.

2. Amplifying background sounds, which can make tinnitus seem less prominent.

A new type of hearing aid, called the open fit hearing aid, may be particularly useful in alleviating tinnitus. The open fit hearing aid can reduce the effects of the tinnitus ringing sensation while still allowing sounds from the outside to pass into the ear. If you think you have tinnitus have your hearing evaluated by an audiologist and to explore the use of hearing aids to alleviate tinnitus. The American Academy of Otolaryngology (AAO-HNS) and the American Tinnitus Association recommends these additional tips for minimizing the effects of tinnitus on your health:

1. Avoid exposure to loud sounds and noises.

2. Get your blood pressure checked. If it is high, get your doctor’s help to control it.

3. Decrease your intake of salt. Salt impairs blood circulation.

4. Avoid stimulants such as coffee, tea, cola, and tobacco.

5. Exercise daily to improve your circulation.

6. Get adequate rest and avoid fatigue.

7. Eliminate or reduce some stress in different parts of your life; stress often makes tinnitus worse.

8. Experiment by eliminating other possible sources of tinnitus aggravation, e.g. artificial sweeteners, sugar, alcohol, prescription or over-the-counter medications. (Do not stop taking medications without consulting with your health care professional about the possible ototoxic impact of your medications.)

What Should You Expect from Your Hearing Evaluation?

More than 32 million Americans have significant hearing loss, yet only a fraction of that number have ever had their hearing tested by a Board Certified Audiologist. Everyone over 25 should have a baseline audiogram! Consider this fact- 17% of all those involved in motor vehicle accidents will have resultant permanent sensorineural hearing loss. However, if you’ve never had a valid hearing evaluation, you’d be hard pressed to show that your hearing was normal prior to such an accident.

A thorough hearing test is the first step in determining if you do, in fact, have hearing loss. The hearing test results also allow your audiologist to recommend the best treatment options if you do in fact have hearing loss. A hearing test is a quick, painless and non-invasive test, and should always be performed by a licensed, Board Certified audiologist. Ask to see the credentials of those who will be doing your testing! As with most health care  professionals, credentialed individuals have the greatest amount of educational training in diagnosis and treatment of hearing impairment, and will offer you or your loved ones solutions that reflect their knowledge base.

Hearing Test Audiogram

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The test begins with a thorough case history, which reviews specific health information that may provide insight into hearing loss causes and will assist in determining which tests should be performed. Following the case history, the audiologist will examine your ear canals and eardrums with a special light called an otoscope. Your middle ear function will also be assessed by a test called tympanometry, which offers insight regarding the status of the area behind your eardrum. This area cannot be easily seen, and so the tympangram offers valuable information to the examiner. The test involves a pressure change, and may replicate the feeling you experience while going up in an elevator, but is not painful in any way.

Next, the levels of hearing in each of your ears should be measured in a sound-treated test booth. Some hearing aid technicians don’t use this type of equipment~ but be wary of any hearing test that is not conducted in such a booth, as reliability may be seriously compromised. During this test, a series of tones of different pitches, as well as speech signals, are presented to each ear through headphones. You will be asked to respond to the signals by either pushing a button, raising your hand or in the case of speech signals, repeating what you heard. You will be asked to respond to the lowest level that you can hear which determines your hearing thresholds. Thresholds for each pitch and ear are plotted on a graph called an audiogram. These thresholds indicate the level at which you are just barely able to detect sound. The speech testing yields a word recognition score, which is important in determining in part how well you will perform with hearing aids, which listening situations will be most challenging, etc.

Further tests may be conducted during the hearing test. Your ability to understand words or sentences at different volume levels or in the presence of noise may be assessed to determine how clearly you hear speech in various conditions. Following the tests, the hearing professional will discuss the results with you and may provide further recommendations, including treatment options, like hearing aids.

If you suspect you have hearing loss it is important to have your hearing tested as soon as possible. The use-it or lose-it principle does apply to our hearing; the sooner you treat hearing loss, the better the outcome of treatment. Most people wait an average of seven years from the time they suspect they have hearing loss until they purchase hearing devices. During that time period, the auditory system is at extreme risk for auditory deprivation, or lack of stimulation due to insufficient volume. This can make a difficult situation worse than it really needs to be. So why wait? Have a Board Certified Audiologist evaluate your hearing as soon as you (or others!) suspect there might be a hearing loss.

Think about the last time you were in a crowded room with kids running around making noise, music in the background, and people chatting. Did you find it hard to focus on what was really being said to you? Did you find you had to “work” to hear the conversation? Was it difficult blocking out the other noises that were either distracting or overpowering the voice of the person speaking to you?

Speaking to people with Hearing LossNow imagine you have a hearing loss.

For those with even mild hearing loss, even a one-on-one conversation in a quite room can be difficult. Phone conversations, which do not allow us the benefit of some body language or unconscious lip reading, can also be challenging for someone with a hearing loss. For these individuals carrying on a conversation in a noisy environment requires them to “work” twice as hard as someone with normal hearing.

Now imagine the conversation you are trying to have includes important instructions, such as how to take medicine in advance of a test or how to avoid driving through a dangerous section of town.

What you say and a hearing-impaired individual’s interpretation of it could be a matter of life or death.

It is important for all of us to become sensitive to those who have hearing loss when we are communicating with them. Being proactive in modifying your communication will make it easier and more fulfilling for everyone involved. Remember, many people do not even realize they have a hearing loss (given the gradual progression of most hearing loss and our body’s ability to accommodate) and because many are embarrassed to admit the hearing loss, they continue to struggle to hear.

To enhance communication and make speaking with those who have hearing loss easier, here are some communication strategies for you to use. Whether you’re a family member, friend, or even a caregiver, communication allows us to be involved with someone’s life and allows them to be involved with ours.

  • Face the person with hearing loss directly so he or she can see your lips. Even if the person is not trained in lip-reading, watching a speaker does help clarify words.
  • Avoid sitting or standing with a bright light behind you. A bright light will put your face in a shadow and makes conscious or unconscious lip-reading difficult.
  • Slow down your speech, making an effort to enunciate each syllable clearly while also emphasizing key words that are important to each sentence.
  • Move your conversation to a quieter area, away from heat vents, noisy or humming appliances.
  • If you are in a restaurant with someone who has hearing loss, ask for a table that is in a quiet area—avoiding seating near the hostess stand, kitchen, vents, or speakers.
  • Avoid speaking to someone with hearing loss in wide-open rooms that have hard floors and hard furniture. Room acoustics can be challenging in more cavernous rooms, especially those with cathedral ceilings.
  • If a piece of the conversation is not understood, try rephrasing what you are saying instead of repeating it. Sometimes just using a different word can help get the message across more easily.
  • Consider assistive listening devices such as television “ears” and phone amplifiers (assistive listening devices) to assist someone in these specific situations.
  • When choosing a cell phone, ask the cell phone dealer for the models with hearing aid compatibility. You can also visit www.accesswireless.org
  • Get the grandchildren involved. Explain to small children that they should gain the attention of, as well as, face the person while speaking. Grandchildren can be encouraged to make grandparents’ listening much easier.
  • Stay patient and do not raise your voice or yell. Yelling can make the words more distorted. Don’t give up trying to communicate; instead try speaking slower and more clearly.
  • Make sure you are in the same room with the person with hearing loss; yelling from a different room creates frustration for both of you.
  • Get hearing protection for yourself and your loved ones. Research indicates that more than 70 percent of all hearing loss is preventable.

Jennifer Bentley, Au.D. - Doctor of Audiology Baltimore, MarylandIn closing, in addition to communicating more effectively with someone with hearing loss, consider being even more proactive. If you have a loved one or even a close friend with hearing loss, encourage him or her to get regular check-ups from a Doctor of Audiology. The doctor will monitor any changes in his or her hearing loss and can recommend treatment options. The audiologist is up-to-date on the latest technology, with advances being brought to market more rapidly than ever as a record number of baby boomers are hitting that hearing loss age, after a lifetime of exposure to our noisy society.

Hearing Loss Contributes to Lost Income & Impacts Employers

When the topic of hearing loss comes up in a conversation, most people don’t think twice about it—dismissing it as a problem faced by “old” people, and more of an inconvenience than a real health issue.

The fact is, hearing loss is a serious condition affecting nearly 30 million Americans. Studies report that one out of six baby boomers (ages 42-60) and one out of 14 in the Gen X population (age 30-41) are affected by hearing loss. Given these age breakdowns, it is fair to assume that most of these individuals are still active in the workforce.

Jennifer Bentley, Au.D. - Doctor of Audiology Baltimore, MarylandFor this large portion of the work force, hearing loss is more than “inconvenient.” If left untreated, even a mild hearing loss can jeopardize safety and cost them (and their employers) dearly.

In terms of safety, consider this: a person with untreated hearing loss, regardless of age, is given instructions to take medicine at specific times and in certain dosages. If those instructions are not crystal clear, the results can be life-threatening. Add in other outside factors such as the noise from the hospital emergency room, or a crying toddler, and the difficulty of hearing proper instructions increases.

The “danger” in these scenarios doesn’t even factor in the ability to hear sirens, smoke alarms, baby cries, car horns, and other alerting signals. The more significant the hearing loss, the greater the risk is to oneself or others, and that’s more than an inconvenience.

In addition to safety, job security and income for an employee with untreated hearing loss may be at risk. Consider a scenario where a boss gives a series of instructions and deadlines to a staff person. Even a mild hearing loss could impair the employee’s ability to hear the details correctly. This puts the project at risk and may even jeopardize that person’s job.

A survey conducted by the Better Hearing Institute indicates, “Working Americans who ignore their hearing problems are collectively losing at least $100 billion a year in earnings.” The survey showed that, “Even people with mild hearing loss, who may miss a consonant here or a word there, may lose income if they can’t completely grasp the latest news at the water cooler or a phone message from the boss.”

The report goes on to estimate that the average worker with untreated hearing loss loses from $1,000 per year (those with mild hearing loss) to $12,000 a year with profound hearing loss.

Given the fact that most hearing loss is noise-induced (contrary to years of thinking it was related to age), it is not likely that the number of people suffering from hearing loss will decline in our noisy society. As a matter of fact, there is an epidemic of hearing loss in young people.

Reports indicate that children as young as 7 are being diagnosed in unprecedented numbers with noise-induced hearing loss. The impact of this epidemic, of course, is yet to even be a reality for employers.

Being Proactive Can Make A Difference

It is easy to be proactive in addressing hearing loss in the workplace. The best place for individuals and businesses alike to begin is with a hearing-loss awareness program. The goal of an awareness program is to commit to the prevention and the proactive treatment of hearing loss for those who are affected.

In terms of prevention, hearing conservation programs are recommended for noisy businesses. When around high levels of occupational noise, the employee’s hearing sensitivity should be monitored on an annual basis. In low-noise environments, such as an office building, employers should include hearing-loss awareness education as part of their worksite wellness programs.

In terms of proactive treatment, encourage employees to get their hearing tested and treated if a loss does exist. Offering to help pay or share the cost of hearing aids (or other assistive listening devices) could speak volumes about an employer’s commitment to staff and hearing health. Such minor “investments” on the part of the business can be huge in terms of employee loyalty and enhancing morale.

Additionally, businesses can take steps to make it easier for employees with hearing loss to hear more efficiently.

For instance, offer phone amplifiers, install loop systems in meeting rooms, and encourage greater sensitivity and awareness among all staff members—offering tips or training to help them communicate more effectively with their co-workers who have hearing loss.

May is Better Hearing Month!

May is Better Hearing month—but despite the fact that more than 34 million Americans report some type of hearing problem, relatively few are screened annually. With about 1 in 10 Americans reporting some type of hearing difficulty, hearing loss is the third most common health problem in the United States. Although hearing problems are commonly associated with the aging process, hearing loss affects all age groups. More than half of hearing impaired persons in the United States are under age 65, including 6 million people between the ages of 18 and 44—and more than 14 million are school-age children. Here are some things to be aware of concerning hearing.

Better Hearing & Speech MonthSound voids. Do you hear “ool” but not sure if someone said “pool,” “tool” or “cool”? Do you find yourself saying “I hear OK, but I have trouble understanding,” or “Soft sounds are too soft but loud sounds are too loud.” Hearing clearly when there’s background noise can be especially difficult for someone with hearing loss and trying to explain your hearing situation can often be difficult.

It’s common for people to be unaware of their hearing loss due to the gradual nature of its progression. As hearing slowly declines, an individual develops compensation strategies without even realizing it. Often it’s others, who are trying to communicate with the hearing-impaired individual, who are more aware of the situation. Hearing problems often go unrecognized, sometimes taking years before sufferers seek professional help.

Causes. There are many causes of hearing loss. Sometimes it’s readily apparent, such as wax build-up in the external ear canal, a condition that’s easily treated but unfortunately goes unrecognized in many individuals. Other causes can include hereditary factors, trauma, ear disease and certain medications. The cause of hearing loss is sometimes presumed. For instance, noise-induced hearing loss attributed to the use of stereo systems or portable music players is a growing phenomenon. Avoiding loud noise may help prevent premature hearing loss and the perception of sound voids.

There are easy ways to tell if a particular sound is potentially harmful. Do you have difficulty talking or hearing others talk over the sound? Does the sound make your ears “ring” (tinnitus), “hurt” or seem “muffled” after exposure? If you answered “yes” to any of these questions, the noise may be damaging your hearing. Most people don’t realize how loud everyday sounds actually are. Nearly 30 million Americans are exposed to dangerous noise levels each day, and 10 million Americans suffer from irreversible hearing damage due to noise.

The diagnostic hearing tests. The purpose of a complete evaluation is to determine the true nature of any hearing loss. The diagnostic process may include a variety of tests, depending on the assessment of your needs: audiometric tests to measure hearing at different pitches; speech evaluation to measure how well you hear and recognize ordinary conversation at different volumes; immittance tests of the middle ear; and complete medical evaluations.

Tinnitus is a medical condition characterized by persistent ringing in one or both ears, which can only be heard by the affected individual. These sounds can come and go; however, most suffers experience symptoms 24 hours a day, 7 days a week. The American Tinnitus Association estimates more than 50 million Americans suffer from tinnitus. It’s also the number one complaint from United States veterans. In some cases, tinnitus retraining therapy (TRT) and tinnitus retraining instruments (TRI) may provide individual solutions.

The balance system, due to its close proximity to the hearing mechanism, is also part of a comprehensive hearing evaluation. Fear of falling is a major health concern of individuals in their latter years. Nearly 300,000 hip fractures result from balance-related falls every year. The natural aging process may affect any one or all of the senses, as well as the central nervous system’s ability to interpret and react quickly to them. It’s very common to hear from someone who has fallen that they saw the curb or step, but just were not able to react fast enough or to keep their balance. With proper diagnosis and therapeutic exercise called balance retraining, many older adults are able to return to a more active lifestyle.

The Communication Needs Assessment in addition to the diagnostic hearing evaluation and after medical evaluation, if an individual still suffers from difficulty communicating; a complete communication needs evaluation is now the gold standard of hearing care. The fist step is identifying the individual’s need: What are the listening situations where the individual would like to hear well? The second step is identifying the individual’s lifestyle. For example, not just if they have trouble hearing in restaurants, but how often they do, or would they like to, go to restaurants.

May is Better Hearing & Speech MonthTechnology alone doesn’t help people hear better. Instead, it’s how well the practitioner works with the individual and applies the technology. If an individual doesn’t see well through a pair of glasses, it’s not due to the “glass,” per se. It has to do with either the measurement of the individual’s vision, the prescription or fit, or some combination. Hearing Aids are similar in application. What helps someone hear better is the correct amount of sound at the appropriate pitches for that individual’s hearing loss, environment and communication needs. Individuals with similar hearing loss may require completely different amplification strategies based on all of the factors mentioned here.

The all-important aftercare completes a comprehensive communication needs assessment for an exceptional sound experience. This includes assessment of need for assistive listening devices for telephone, Bluetooth, TV, loops or music systems. In addition to assistive solutions, aftercare will include lip reading and listening skills counseling.

It’s important that a hearing-impaired individual take an active role in listening and participate in the recommended auditory retraining and rehabilitation program to ensure he or she hears and understands as much as possible. The auditory system may not have heard certain voices and sounds for many years, and the reintroduction of new sounds and voices needs to be presented gradually. In other words, just as the hearing loss may have occurred gradually, the reintroduction of new sound needs to occur gradually. Through this process, each individual will adapt and develop necessary listening skills.

A hearing screening can quickly and accurately evaluate an individual’s hearing, determine the degree of hearing loss and put them on the path toward treatment. After treatment, it’s important to monitor the hearing loss to ensure the technology is meeting an individuals needs.

Sound Advice: Noise-Induced Hearing Loss Prevention

April 22nd, 2011

Have you noticed that daily life in our society gets louder every year? The change is subtle and is a problem that most of us take for granted and even ignore. According to many leading Audiology professionals, casually ignoring the sounds around us can lead to serious hearing problems, including noise-induced hearing loss (NIHL).

One of those professionals is David Coffin, Audiology clinic coordinator at Indiana’s Ball State University. “We are exposed to all sorts of sounds that can lead to permanent hearing loss,” Coffin says. “The average person will wear a helmet when riding a bike, or a seat belt in a vehicle, but doesn’t even think about ear protection when going to watch a rock band, a fireworks display, or even an auto race.”

According to the Better Hearing Institute, 30 million Americans are exposed to dangerous noise levels each day and 10 million Americans have already suffered irreversible hearing damage from noise.

The problem of noise induced hearing loss has been around for decades. It occurs at home, in the yard, at the office, at the factory, on the farm and in the military. But today, because of technology, virtually everyone is effected and at younger and younger ages. It is not uncommon for audiologists to see 20-year-olds with the hearing of 60-year-olds.

However, there is good news as well: NIHL is easily identifiable and completely preventable. Today, audiologists can assist with the prevention, diagnosis and rehabilitation of hearing loss.

Hazardous Noises

Normal conversations occur at approximately 60 decibels. Raising your voice over a noise in order to be heard by someone an arm’s length away is a good indication that the noise could be within risky range. Knowing which noises can cause damage, such as jet engines, lawn mowers, motorcycles, chainsaws, powerboats, and personal media players is the best arsenal against NIHL.

“Risky noise,” says Coffin, “can come in the form of the pop of fireworks, the snarls of traffic, the buzz of lawn mowers, or the percussive tones of marching bands.”

According to Coffin, such sounds are typically within the range of 90 to 140 decibels, but any noise above 80 can cause long-term hearing damage. The maximum exposure time per day for the exposed ear is 8 hours at 90 decibels. The risk of noise-induced hearing loss depends on both the intensity and duration of the exposure. As intensity increases, the length of time for which the exposure is “safe” decreases. For example, exposure to 85 decibels (often produced by gas-engine lawn mowers) for 8 hours can be as equally damaging as exposure to 110 decibels (often produced by a chain saw) for only a few minutes. For every 5 decibel increase in volume, the maximum exposure time is reduced by 50 percent. Therefore, according to Sight and Sound Associates, the maximum daily exposure time at 95 decibels is four hours; at 120 decibels, seven minutes, 30 seconds.

Warning signs that exposure to hazardous noise has occurred or is occurring include: the inability to hear someone a few feet away, ear pain after leaving a noisy area, ringing or buzzing (tinnitus) in the ears immediately after exposure to noise, or hearing people talking but being unable to understand them.

Loud explosions that peak for a few milliseconds at levels greater than 130 to140 decibels may cause hearing loss. More often, however, hearing loss is caused by repeated exposure to noise above 85 decibels over long periods. Some sources of common noises and associated decibels are: lawn mower, 90 decibels; stereo headphones, 105-110 decibels; automobile horn, 110 dB; baby’s cry, 115 decibels; rock concert, 115-120 decibels; and firearms, 125-140 decibels.

The commercial popularity of portable media players with earphones, such as the iPod and similar devices, and their long-term use by consumers, increase the risk of NIHL in those users. According to the National Center for Health Statistics, almost 15% of Americans below the age of 19 suffer from some measure of hearing loss. And according to Sight and Hearing Association, the incidents of teenage hearing loss has increased 400 percent over a ten-year period, as found in a recent study of eighth graders.

Symptoms of NIHL

NIHL usually develops gradually. People may lose a significant amount of hearing before becoming aware of its presence. The first sign of NIHL is not being able to hear high-pitched sounds, such as the singing of birds, or not understanding speech when in a crowd or an area with a lot of background noise. If damage continues, hearing declines further, and lower pitched sounds become hard to understand.

Signs of hearing loss from unsafe sound exposure include the inability to comprehend somebody talking from two feet away, hearing muffled speech, experiencing pain or ringing in the ears following exposure, and needing others to speak louder in conversation.

People often fail to notice the impacts of unsafe exposure to noise because it causes few symptoms. Hearing loss is rarely painful. Symptoms may go away minutes, hours or days after the exposure to noise ends. Many people naturally assume that if the symptoms abate, their ears have recovered to normal. However, even in the absence of more symptoms, some cells in the inner ear may have been destroyed by the noise. Hearing returns to normal only if enough healthy cells are left in the inner ear. But if the noise exposure is repeated and more cells are destroyed a lasting hearing loss will develop.

Sensorineural Hearing Loss

When the hearing system is exposed to noise at a risky or hazardous level, mechanical and metabolic changes can occur. Scientific research, based on studies of industrial workers, as well as lab studies of humans and animals, have investigated the effects of noise on hearing.

In these studies, excessive noise stimulated cells in the inner ear, resulting in chemical processes that can exceed the cells’ tolerance. This damages cell function and structure and results in sensorineural hearing loss (as opposed to a conductive hearing loss, where the outer or middle ear have been affected) and tinnitus (ringing of the ears).

The sensory cells in the cochlea may recover from their damage (as you have possibly experienced after a loud concert or work with a loud machine). Usually, recovery from temporary threshold shift (or TTS) occurs quickly, largely disappearing in 16 to 48 hours after exposure to loud noise. However, if the hearing sensitivity does not recover within a few days, an irreversible and permanent threshold shift has taken place.

Prevention

Hearing loss is not reversible, but NIHL is preventable. Individuals vary in their susceptibility to hearing loss and hearing typically declines with age, but a healthy person who is not exposed to hazardous noises can enjoy normal hearing into his senior years.

Noise is probably the most common occupational hazard facing workers today. Employers at noise-hazardous workplaces, and physicians, are in a position to advise those at risk for developing NIHL that there are three simple keys to prevention:

1)      Understand what noises put them at risk – those above 85 decibels, commonly portable media players, lawn mowers, motorcycles, chain saws, jet engines, etc. A general rule of measurement is that if one has to shout to be heard an arm’s length away, assume the noise is above a hazardous threshold.

2)      If possible, decrease noise at the source – for example, keep the volume low on portable media players, purchase motorized equipment with an effective muffler, etc.

3)      Buffer loud noises with earplugs or other forms of hearing protection. These are known as hearing protective devices (HPDs) and are required by law to be labeled with a Noise Reduction Rating (NRR) based on performance obtained under ideal laboratory conditions. HPDs are powerful tools for preventing NIHL if worn correctly and throughout the duration of the hazardous noise. Also sound absorbing materials, such as floor mats, can help reduce noise.

Early identification is important in order to recognize the presence of NIHL and take steps to prevent further hearing loss. Those regularly exposed to hazardous noise in the workplace or elsewhere should have an annual hearing test. If hearing loss is developing, it might indicate under-protection and could suggest preventative measures, such as better HPDs or turning down the volume on the iPod

For many of you between the ages of 46 to 64, your time is coming.

Time, that is, to experience what so many of your parents and grandparents came to learn of fist hand: hearing difficulties caused by exposure to excess loud noise.

The “Baby Boomer” generation – those Americans born between 1946 and 1960 – accounts for some 76 million of us in the Untied States today and at least 15 percent of Boomers already have hearing loss.

This is a far cry from the previous 2 generations, who typically did not show symptoms of hearing loss until they were in their 70’s and 80’s.  Indeed, when I was an audiology student at Minot State University earning my Master’s of Science degree I was taught that only men in their 70’s and 80’s got hearing loss.

What has changed?  Our world is now much, much louder.

An Unprecedented Century

Prior to the Industrial Revolution of the 1890’s, relatively few Americans were exposed to loud noise.  At the turn of the 20th Century, much of our population inhabited rural areas with males working in non-mechanized agriculture and females involved in homemaking chores, which they performed by hand.  There were no vacuum cleaners or food processors.

However, with unprecedented technology, mechanization, and involvement in two World Wars, the US population got its first dose of exposure to excessive levels of loud noise.

Still, the field of audiology – born of the technological research in sonar for the Navy in WWII  — was in its infancy in the 1950’s and was relying on the only set of data on hearing loss available till then, which was testing conducted at the 1939 World’s  Fair in San Francisco.

But a funny thing happened.  That data was proven wrong when, in the mid 1980’s women in their 60’s started showing up in audiologist’s offices across the country with identical hearing loss of their male counterparts.

Audiologist & Ear Doctor, Dr. Crystal Chalmers, Chico, CaliforniaWho were these women and why, for the first time in recorded history, were they suddenly experiencing hearing loss?  She was, in fact, the “Rosie the Riveters” of WWII: those young American women who, with all the men serving in the armed forces, went to work in the factories and shipyards providing the “Arsenal of Democracy” with much needed war effort labor.  These women built the Liberty ships, Sherman tanks, and B-17 bombers used to defeat the Axis Powers …. And got themselves a hefty dose of impaired hearing in the process!

Post War Boom

After victory in WWII Americans got busy in the greatest economic surge in human history … and had babies.  Lots of babies.

And as those babies grew into young adults in the 60’s and 70’s a flourishing American economy provided them with all sorts of loud recreational activities.  From rock concerts to ski boats to hot rods to stereo systems, Americans got a steady diet of loud noise long before subsequent research showed the direct correlation between the noise and hearing loss.

Early Hearing Aids: Low-Tech = Bad Reputation

Parents of the Boomers had lousy timing as hearing aids back then were pretty awful.  These devices only made sounds louder for the wearer.  While a few people benefited from this simplistic approach to solving hearing difficulties, most did not and hearing aids got a deserved bad reputation.

So bad in fact that after graduating from school, I steered my career towards diagnostics, performing testing of the hearing system for the determination of medical problems such as the location and size of brain tumors and loss of balance problems.

The Digital Breakthrough

Everything about hearing aids changed in the late 1990’s with the breakthrough of digital hearing technology.  In essence, digital hearing aids are miniature computers that dramatically increase the amount of sound processes possible (and available to the wearer) as opposed to the old linear and analog products.  And digital products keep getting better, with several major advancements taking place during the last decade with the last two years seeing some terrific gains.

Today’s digital products are so advanced we don’t even call them hearing “aids” anymore.  Instead we prefer to call these amazing products “hearing technology” as they are smaller than ever with superb sound quality.  Top-of-the-line models have features that Boomers need such as “directionality” for enhancing sound coming to from the front, while tuning down sound coming from behind such as someone might experience at a noisy restaurant or party.  Also, Bluetooth capability enhances the lives of 21st century on-the-go active Americans.

Educate Yourself: Get the Facts about Hearing Care

The myths and misperceptions associated with hearing loss and hearing aids of 30 years ago should be put to rest.  The science of Audiology has come a long way as has hearing technology.  No one needs to suffer all the serious communication issues associated with hearing difficulties … if they would only seek help.

Get the facts!  As the month of May is National Better Hearing Month, I will be providing a Free Luncheon Seminar on Hearing Care on Wednesday May 4th at the Chico Women’s Club.  This informative seminar will answer all of your questions about hearing difficulties and technological solutions.   The seminar if free but advance reservations are required, so call my office at 1 (888) 893-1352 … because hearing is a wonderful gift!

SIDEBAR:  More baby boomers showing signs of hearing loss

  • More than 55 million Americans have some degree of hearing loss—approximately one in 5 individuals — and this number is expected to increase further by 2030.  Much of that looming surge is a baby-boomer phenomenon.
  • Among Americans ages 46 to 64, about 15 percent already have hearing problems, according to a survey by the Better Hearing Institute.
  • Two out of three people with hearing loss are below retirement age.
  • Sixty percent of people with hearing loss are male.
  • Only 12 percent of physicians today ask patients if they have any hearing problems.
  • Only one in five people who could benefit from hearing aids currently wear them.

Did you know hearing loss…

  • Is the third most prevalent chronic health condition in America, behind high blood pressure and arthritis?
  • Affects 36 million Americans (about 17% of adults)?
  • Is more common in men than women?
  • Costs our economy billions of dollars in lost wages and hidden costs annually?

Is not being adequately identified by healthcare professionals? Only 38 percent of adults ages 70 years and older and only 29 percent of adults ages 20 to 69 have had their hearing tested within the last 5 years!

Do you or someone you love have a hearing loss? If so, you’re not alone. Almost 20% of adults in the United States will develop hearing loss during the course of their lives, and if undiagnosed and untreated, its affects can be devastating. Impaired hearing can have a profound impact on emotional, physical, economic, and social well-being.  People with hearing loss have documented decrease in quality of life, reporting symptoms of depression, dissatisfaction with life, reduced functional health, and social isolation. Statistically, they have lower income levels, and frequently complain of frustration in relationships and various communicative situations, as well as inability to enjoy social situations, and fatigue. Despite the fact that most people with hearing loss can be helped with today’s state of the art amplification, many never seek help, or resist the use hearing aids or other assistive listening technologies.

The causes of hearing loss are varied and resultant impact on auditory capability may range from mild to pronounced. Sometimes the cause or etiology, such as wax build up in the external ear canal or an ear infection, is readily apparent. In other instances, the cause of hearing loss may be more obscure. Decreased hearing is often called “the invisible handicap”. Because hearing impairment (especially loss related to aging) often presents very gradually, those with significant hearing impairment can be unaware of their loss. Family members, significant others, co-workers and friends are frequently the first to notice communication problems related to decreased hearing sensitivity.

Given that 36 million Americans are faced with this “invisible handicap” what kinds of risk factors increase the likelihood that someone will develop hearing loss? Why do some people develop hearing loss and while others do not? Some risk factors are obvious, but others are much more obscure.

Perhaps the most widely recognized risk factor is aging. Presbycusis, or the loss of hearing that gradually occurs as we grow older, is a familiar scenario for those of us with older family members. In fact, about 30-35 percent of adults between the ages of 65 and 75 years have a hearing loss, while an estimated 40-50 percent of people 75 and older have a hearing impairment.

Loss associated with presbycusis is usually greater for high-pitched sounds, resulting in the frequent comment “I can hear people talking, but can’t understand them clearly”. It is most commonly binaural (in both ears), affecting the ears equally. Because this type of loss in hearing sensitivity is so gradual, people who have presbycusis frequently lose their frame of reference for normal loudness of sounds, and often do not realize that their hearing acuity is diminishing.

The resultant relationship dynamic is frequently the subject of jokes – “My husband suffers from ‘selective’ hearing and he’s driving me crazy”! In reality, however, hearing impairment is no laughing matter and can take quite a toll on communication with significant others. Research indicates that for couples where one person has unaddressed hearing loss, the divorce rate is actually significantly higher.

Most people would agree that we now live in a very noisy world. Noise levels for rock concerts, radios, motorcycles, traffic, industrial and lawn equipment, and even our personal listening devices constantly bombard our auditory system. It is not surprising that noise exposure is another one of the most frequently cited risk factors for hearing loss, and now rivals aging as the number one cause of hearing loss in this country.  Noise from occupational, recreational and sporting activities all pose significant hazards to hearing in the United States today. Firearm use is one of the biggest culprits in our area of the country. A single shot from a shotgun, experienced at close range, can permanently damage hearing.  Repeated exposures to loud machinery in the work place or as part of yard maintenance or recreational experience may, over an extended period of time, present a serious risk to hearing. Even something as seemingly benign as blow dryers for styling hair put hearing at risk.

Consider the noise levels for such activities as NASCAR, jet ski and power boat usage, and lawn equipment. The cumulative effects of these noise hazards and many others pose a serious risk for hearing. Noise exposure risk is a time weighted function – in other words, the longer the exposure time, the greater the risk, and lower the loudness level required to cause damage. According to the National Institute on Deafness and Other Communication Disorders (NIDCD), 10 million Americans have already suffered irreversible hearing damage from noise, and 30 million more are exposed to dangerous noise levels each day. A one-time exposure to hazardous noise resultant from gunfire or a rock concert, no matter how brief the time, of 120 dB or more can leave hearing permanently impaired. Prolonged exposure to only 85 dB (which can be generated by a commonly used appliance such as a blow dryer or hand held power tool) can do the same. 

Children and young adults are bombarded with potentially damaging noise exposure, most of which is easy to overlook. Most people intuitively recognize that “boom boxes”  IPODS, and other personal listening devices, if played too loudly, constitute a risk to hearing. However, consider the noise levels inherent to playing in a school band or orchestra. Students engaged in this commonplace activity spend hours practice in noisy environments within the context of their academic activities, yet many of them are not wearing appropriate ear protection, nor are schools effectively addressing this problem. To complicate matters, for reasons that are not fully understood some people are more susceptible to noise exposure than others.  As an example, research indicates that those with blue eyes are more prone to noise exposure than those with darker eye color!

Aging and noise exposure are two rather obvious risk factors for hearing loss, but there are many other factors that are more insidious. Studies suggest that there is a strong genetic component inherent to hearing loss, both for childhood deafness as well as presbycusic loss. If your parent or grandparent had hearing loss, your risk factor for developing a similar impairment may increase. If you had a relative who was hearing impaired from birth, family members of child bearing age need to be mindful of this risk factor, and be particularly vigilant with regard to insuring that the newest members of the family are effectively screened at birth for hearing sensitivity.

Various diseases of the ear certainly pose risk to hearing sensitivity. Ear infection, otosclerosis (a bony growth in the middle ear cavity), Meniere’s Disease, acoustic neuroma (a tumor on the auditory nerve), and a host of other maladies are obvious risk factors for hearing loss. But did you know that hearing loss is about twice as common in adults with diabetes compared to those who do not have the disease, according to a new study funded by the National Institutes of Health (NIH)? Visual deficits have long been associated with diabetes, but hearing loss is an under-recognized complication. Because of the strong correlation between diabetes and hearing loss, The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), recently suggested that people with diabetes should consider having their hearing tested.

Use of common drugs such as antibiotics, aspirin, diuretics and chemotherapy can cause hearing loss. Typically, hearing loss from ototoxic drugs is high frequency, which often results in the hearing impairment less obvious to those it affects. All radiation and chemotherapy patients should insist on baseline hearing assessments before, during, and following their course of treatment to insure that auditory effects of ototoxic interventional strategies are carefully monitored and treated.

Race and gender also play a role in hearing loss risk factor determination. Researchers now know that compared to women, men are five and one half times more likely to have hearing loss. White and Mexican American men have a higher incidence of both high-frequency hearing loss and hearing loss in both ears than blacks, who were 70 percent less likely than white participants to present with hearing loss.

With the dramatic increase in airbag use, motor vehicle accidents (MVA’s) are common culprits for increased risk of hearing loss. In fact, 17% of those involved in MVA’s with airbag deployment will have permanent loss of hearing as a result. Other insidious risk factors for hearing loss include smoking and cardiovascular disease. The incidence of hearing loss is significantly more pronounced among smokers, as well as those with any type of cardiovascular disease.

Many healthcare professionals simply don’t make these associations, and as a result, do not refer patients for hearing evaluation as often as risk factors might dictate. So, the message is be aware, and be proactive in assessing your risk, or that of your loved one, for hearing loss. For a comprehensive audiometric evaluation, see a Board Certified Doctor of Audiology. If you’ve never had a baseline audiogram, it’s certainly in your best interest to do so. Only 38 percent of adults ages 70 years and older and only 29 percent of adults ages 20 to 69 have had their hearing tested within the last 5 years.   If you’re over 65, hearing evaluation each year by a Board Certified Audiologist should become part of your annual medical maintenance program.

New Smoke Alarm Requirements Will Save Lives

June 4th, 2010

As many of you are probably unaware, a new National Fire Alarm Code went into effect in January 2010.  The change is the result of mounting research evidence indicating that millions of Americans could potentially sleep through their smoke alarms during a fire.

Most standard smoke alarms in the US produce high-frequency tones between 3000 to 4000 Hz.  Unfortunately, this high-frequency range is also one of the first to be effected by hearing loss.  About 30 million Americans, or 1 in 10, have some degree of hearing impairment.  According to the National Institutes of Health (NIH), about 18 percent of adults ages 45-64 have hearing impairment, compared with 30 percent of adults 65-74 and almost 50 percent of adults over 75.

The new National Fire Alarm Code would require the use of a low-frequency signal (520 Hz) for fire alarms installed in residential bedrooms of those with mild to severe hearing loss by January 2010 and in all commercial bedrooms by 2014.  This low-frequency tone has been found to be significantly more effective in waking up individuals with hearing loss and those in a deep sleep, even more effectively than strobe lights or bed shaking devices alone.

Fire is the third leading cause of accidental death in the US.  Most fire fatalities occur at night, between the hours of about 10 p.m. to 7 a.m., when the vast majority of people are asleep.  The National Fire Protection Association (NFPA) reports that adults above the age of 65 have about twice the risk of fire fatality than the average and those over 85 have four and half times the risk.  These figures are especially troubling, given the fact that these groups are also at a much greater risk of not hearing their smoke alarms. 

If you or a loved one suffers from even a mild hearing loss, a traditional smoke alarm may not be enough to awaken you from a deep sleep.  Often times you only have a few minutes to escape a house fire once the alarms have detected smoke.  Serious consideration should be given to whether a low-frequency smoke alarm or some other form of alerting device would be the best choice for your needs in case of a fire.  Speaking with an audiologist will help you determine the most appropriate options based on your individual hearing needs.

Fire Facts from the NFPA:

  • In 2008, U.S. fire departments responded to 386,500 home fires. These fires killed 2,755 civilians. Eighty-three percent of all fire deaths resulted from home fires.
  • Someone was injured in a home fire every 40 minutes and roughly eight people died in home fires every day during 2008.
  • A fire department responded to a home fire every 81 seconds.
  • Almost two-thirds of reported home fire deaths in 2003-2006 resulted from fires in homes with no smoke alarms or no working smoke alarms.
  • About 1/3 of home fires and deaths happened in the months of December, January and February.
  • The kitchen is the leading area of origin for home fires. However, bedrooms and living/family rooms are the leading areas of origin for home fire deaths.
  • One-third of American households who made an estimate thought they would have at least 6 minutes before a fire in their home would become life-threatening. The time available is often less.
  • Smoke alarms that are properly installed and maintained play a vital role in reducing fire deaths and injuries. Having a working smoke alarm cuts the chances of dying in a reported fire in half.
