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!

The Consequences of Untreated Hearing Loss: Why You Shouldn’t Wait to Seek Help for a Hearing Difficulty

April 18th, 2012

After over 30 years as an audiologist, I have heard a lot of reasons from a lot of patients as to why they had not addressed their hearing difficulties sooner.

And of course, I always explain to them that ignoring a hearing difficulty won’t make it go away, and that there are consequences for not treating a hearing loss.

Audiologist & Ear Doctor, Dr. Crystal Chalmers, Chico, CaliforniaNow there is even more evidence – gleaned from scientific studies by some of the top researchers in the world –  to support what audiologists like myself and many of my colleagues with Audigy Group have been saying all along: don’t wait to get tested and – if the tests do indeed show a hearing loss – discuss treatment options with your hearing care professional.

These studies clearly show that hearing loss doesn’t just affect one’s ability to hear the TV or communicate with a spouse, friends, or co-workers.  There can be serious implications for brain atrophy and cognitive function.

Study Results Released at Audiology Conference

A number of these studies were presented and discussed at the American Academy of Audiology’s “Audiology NOW! 2012” annual international conference which was held March 28 thru March 31 in Boston, Massachusetts.   I attended this conference and took in several of these workshops, notably one titled “Issues in Cognition, Audition, and Amplification: A Panel Discussion”.

This extremely informative workshop was presented by a panel comprised of six highly respected researchers from the USA, Canada, and northern Europe.

The presenters and their topics were:

● Larry E. Hulmes, Ph.D., Indiana University “Higher Level Processing Abilities”

● Ulrike Lemke, Ph.D., Senior Researcher, Phonak International, Zurich, Switzerland “The Cognitive Part of Successful Speech Recognition”

●  Brent Edwards, Ph.D., Starkey Research Laboratories, Eden Prairie, MN “How Hearing Aid Technology Can Affect Cognitive Function”

● Kathy Pichora-Fuller, Ph.D., University of Toronto, Canada “Can Hearing Aids Accelerate Listening and Speech Understanding?”

● Thomas Lunner, Ph.D., Eriksholm Research Center, Oticon International, Denmark, and Department of Behavioral Sciences and Learning, Linkoping, Sweden “Memory Systems in Relation to Hearing Aid Use”

● Frank Lin, M.D., Ph.D., Johns Hopkins Medical Institutions, Baltimore, MD “Hearing Loss and Dementia”

Collectively these presenters showed how brain function and hearing loss are intertwined and that when left untreated hearing loss clearly affects cognitive function.  Of special interest were findings on how the use of hearing aid technology could produce marked improvements in those who had had cognitive decline caused by untreated hearing loss, much the same as physical therapy can be used to restore deteriorated muscle mass.

University Study Links Brain Atrophy with Hearing Loss

A recent study by researchers at the Perelman School of Medicine at the University of Pennsylvania – the results of which were released in August of last year – show that declines in hearing ability may accelerate gray matter atrophy in auditory areas of the brain.  This shrinkage of the brain in areas important for hearing comprehension can cause an increase in the effort needed by the affected person to successfully comprehend speech.  This need for increased effort can be particularly troublesome for older adults as the amount of energy used for “hearing” can impact other areas in the affected person’s daily life.

The study found that people with hearing loss showed less brain activity on functional MRI scans when listening to complex sentences.  Poorer hearers also had less gray matter in the auditory cortex, suggesting that areas of the brain related to auditory processing may show accelerated atrophy when hearing ability declines.  In general, the study showed that loss of hearing sensitivity “has cascading consequences for the neural processes supporting both perception and cognition.”

“As hearing ability declines with age, interventions such as hearing aids should be considered not only to improve hearing but to preserve the brain,” said lead author Jonathan Peelle, Ph. D., research associate in the Department of Neurology.   The research for this study can be found in The Journal of Neuroscience and was funded by the National Institutes of Health.

May is National Better Hearing Month!

Two Ears are Better than One… The Advantages of Binaural Hearing

Has your audiologist recommended “binaural hearing devices”? Don’t panic. Binaural simply means “two ears” – which is what nature gave you. Two ears are, indeed, better than one for a number of reasons. Just like our eyes, our brains are wired to receive sound from both ears. Many first time hearing aid wearers think starting with just one hearing aid may be easier to adjust to or save them some money; however, two hearing aids are truly better than one. Here are some reasons why:

• Better localization – the ability to tell where sounds are coming from

• Better hearing in background noise

• Better sound quality (“mono” versus “stereo”)

• Better hearing for soft sounds such as children’s voices and sounds of nature

• Less strain on you while listening – with only one hearing aid you may often strain to hear various sounds and become fatigued, with two hearing aids listening is more relaxed

• Listening balance – you won’t be turning your “good” ear to hear. Higher success and satisfaction – studies indicate people who wear two hearing aids are much more satisfied with their hearing aids.

Studies have also shown when only one hearing aid is worn and the other ear is deprived of sound, the “use it or lose it” principle applies, causing the onset of auditory deprivation in the non-amplified ear. In other words, the word recognition ability in the unaided ear decreases from lack of stimulation – and this spells trouble for those who think they can successfully add a second aid – later.

So, you may save a few dollars by going the one-hearing-aid route but you may also find that one hearing aid causes more trouble than what your savings is worth. Let’s take a closer look at why two hearing aids are almost always better than the one-hearing aid approach to hearing loss.

Improved Localization

Localization is the ability to detect and determine the source of a sound. It’s a natural and sophisticated process that enables you to pinpoint the exact location of a bird twittering in the trees 100 yards away, for example. The reason for this is simple. Sound travels in waves – disturbances in the air. The hair cells in our inner ears  have the miraculous ability to turn mechanical sound waves into electrical impulses that are sent to the hearing centers of the brain where the sound is interpreted and localization occurs. When that bird tweets and twitters, the sounds it makes reach one ear slightly ahead of the other ear. If the bird is to your right, the right ear hears the sound a split second before the left ear.

The brain is able to localize the sound because of this split second difference in the time it takes the sound to be processed. The hearing centers of the brain are able to pinpoint the location and source of the sound. Localization is an essential part of the listening experience. It warns us of danger, points us in the direction of a distant caller or tells us which machine is running on the factory floor.

The ability to pinpoint the source of a sound is something you use everyday, though you may not even realize it. In fact, in most cases, you DON’T realize it. It happens automatically – at least when both ears are operating at peak performance levels. Indeed, you may save a few dollars by only buying a hearing aid for the ear that’s experiencing hearing loss but you’ll also lose some or all of your ability to place the source of critical sounds. And that’s not going to enhance your hearing. In fact, it may actually cause confusion and place you in danger because you think the car horn is coming from over there when, in fact, it’s coming from right behind you.

Many new hearing devices employ wireless communication between the two instruments – allowing them to work together to ensure localization cues are maintained between the two ears. The left and right hearing aids communicate with each other to ensure they are utilizing the same listening strategies in different environments.  When two hearing devices are wirelessly linked, they “talk with each other”. This allows the two hearing aids to improve the ability to locate the direction of sounds and ultimately improve your listening experience.

The result? You’ll be able to localize sound – to precisely pinpoint the source of all the sounds you hear throughout the day. This is especially important when in background noise.

Easy Listening

No, we’re not talking about music here. Advantages listed of wearing two hearing aids include improved listening in background noise as well as reduced strain while listening. Let’s face it, background noise is annoying – even for people with normal hearing! So for persons with hearing loss wearing hearing aids, background niose can be even more annoying. Using two hearing aids, properly tuned to address the different hearing loss of each ear, cuts through some of this background noise enabling you to hear more clearly. The brain retrains itself to filter out unnecessary noise while picking up the sounds of your dinner companion without having to turn your head so your hearing aid is pointing directly at the speaker. This not only improves your ability to listen in background noise, but you will no longer have to strain to hear.

Improved Sound Quality

Mono versus stereo sound. Which sounds better? Stereo, of course. And with two hearing aids, properly adjusted to meet the differing hearing needs of each ear, you enjoy a better quality of sound. In simple terms, the world sounds better in stereo.

A soft sound may go undetected by one ear but picked up by the other ear – the one closer to the source of the sound. Your ability to hear the soft sounds that you’ve always taken for granted is greatly improved when you go binaural because both ears are amped to the proper level to hear even the soft whisper of a loved one – and that’s something that you just can’t put a price tag on.

Hearing Balance

The natural state of binaural hearing is hearing with both ears in balance. An audiologist or hearing aid professional can adjust each hearing aid to fit your hearing needs, delivering hearing balance and a much improved listening experience.

The Listening Experience

Talk to your audiologist about options. The best course is the one that delivers the most satisfying listening experience – the listening experience that you’re used to. The one you’ve enjoyed all these years.

Hearing is a quality of life consideration. So, spend the extra few bucks to get improved localization, hear-through sound that’s natural and organic. Get back your ability to hear soft sounds or sounds in higher frequency ranges and skip the stiff neck syndrome that a single hearing aid creates as you turn your head throughout the day to hear. Go binaural and get back into life. Hear the way nature intended you to hear – with two ears. The cost, when weighed against the benefits, is insignificant.

You’ve got two ears. Might as well use them both to hear the world around you. After all, you don’t want to miss a single sound.

Why Should I Pay for a Hearing Test?

This question has been asked of us on a number of occasions in our private audiology practice. Audiologists are extensively trained healthcare providers similar to primary care physicians (PCPs), nurses, optometrists, and dentists. So it is a bit of a puzzle when we consider the reason some would ask why they have to pay for our medical services; few are likely to ask if they have to pay for a visit to their PCP when they have a cold, or for a visit to their optometrist for an eye test in order to get new glasses or contacts.

“I can get one just down the road for free.”

Audiologist, Kumiko T. B. Dunn, Ph.D., CCC-AThis statement often follows the first and brings to light the reason the first question got asked. By “down the road”, the questioners are often referring to locations where hearing aids are sold, often by people licensed as “hearing aid dispensers” and not audiologists. Hearing aid dispensers have primarily been trained to test their patients’ hearing for the purpose of deciding if a patient might be able to wear hearing aids successfully. Audiologists have, of course, also been trained to do this but the bulk of their education (8+ years beyond high school) is in the science of determining the possible source of a person’s hearing problems. In addition, audiologists are trained to determine the most effective treatment options for a patient’s unique needs, including hearing aids, cochlear implants, bone anchored hearing aids, middle ear implants, aural rehabilitation and assistive listening devices [ALDs]. Hearing aids can be an effective tool in improving one’s ability to understand conversation and communicate with others but the audiologist’s role is to use all tools available to improve these important aspects of life. Finally, there is also a difference between the hearing aid dispenser and the audiologist in the eyes of the insurance company. If a person’s insurance coverage will pay for a hearing test, a hearing test done by an audiologist will generally be paid for by insurance; a hearing test done by a hearing aid dispenser, however, typically will not.

We provide a complete and comprehensive hearing evaluation that will be used to provide you with the best hearing care possible. The team of audiologists and staff at East Valley Hearing Center hope that this provides a better understanding of why we ask for payment for our services. We are here for far more than to simply sell hearing aids. Our objectives are to determine the possible reason(s) for our patients’ hearing difficulties and to provide recommendations for the most effective ways to help relieve or reduce them.

East Valley Hearing Center is composed of providers, who are Doctors of Audiology (Au.D.) and Ph.D. Audiologists, Audiology Assistants, and support staff. We would be happy to serve you and your hearing needs.

Constant Ringing in Your Ears?

February 1st, 2012

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.)

A recently completed study by Johns Hopkins University – published on November 14, 2011 in the Archives of Internal Medicine – now confirms that 1 in 5 Americans have hearing loss in at least one ear.  This is well over 50 million people and far exceeds previous hearing care industry estimates of approximately 25 million.

The Johns Hopkins study is unique in that the data used statistically corresponded with the entire US population by including both men and women of all races, aged 12 and older, living in cities throughout the country.

Using the World Health Organization’s definition of hearing loss – not being able to hear sounds of 25 decibels or less in the speech frequencies – the Johns Hopkins researchers found that over 30 million Americans have hearing loss in both ears and that over 20% of the population – in excess of 50 million people – have hearing loss in at least one ear.

Despite there being so many of us with hearing difficulties, too many people are still unaware of how or where to obtain professional help as the misconceptions about hearing loss and hearing aids are commonplace in our society.   The fact that you are reading this article is an excellent first step towards empowering yourself (or a family member) and taking control of your hearing health.

Audiologist & Ear Doctor, Dr. Crystal Chalmers, Chico, CaliforniaCommon Hearing Loss and Hearing Aid Myths

Myth: Buying hearing aids online, by mail, or at a big box store saves time, money, and gets the same results as professionally fit devices.

Fact: The proper diagnosis and selection of hearing technology as a solution for hearing difficulties is not the same thing as purchasing common consumer goods.  Rather, it should be a process built upon a relationship of respect and trust between the patient and a highly trained, competent, and ethical professional whose services and products provide long-term value.

Myth: Anyone licensed to sell hearing aids is qualified to test a person’s hearing.

Fact: By law in the state of California, only audiologists are licensed to perform diagnostic hearing evaluations.  The “free” tests that hearing aid dispensers frequently advertise are not comprehensive exams and are merely designed to determine if a person could be helped by a hearing aid.

Myth: Hearing loss affects only “elderly” people and is merely a sign of aging.

Fact: Hearing loss can affect people of all ages.  As mentioned in the Johns Hopkins study, 20% of the US population aged 12 years and older have hearing difficulties severe enough to impact communication.

Myth: Hearing aids don’t really do anything but amplify sound.  Besides they’re unsightly and uncomfortable.

Fact: While the hearing aids from 20 years ago left a lot to be desired from both technology and cosmetic standpoints, today’s hearing devices are exceptional technological performers and are so small as to be very discreet.  However, the most important consideration for you, the consumer, is not what the product is, but rather how it is fit to your hearing lifestyle, and to what extent you are provided with expert follow-up in the fitting of that device.   That is what makes my patients so successful in being able to enjoy better hearing.

Would you like to learn more about solutions to hearing difficulties and  hearing aid technology?  Here are two great places to start:

#1.) My Internet website at www.nsaudiology.com. This educational website offers a world of information, including highly informative videos, a free guide to better hearing, online specials, current “News & Events”, and the “Ask Dr. Chalmers” section where I have posted previously published original articles such as the one you are reading now.

#2.) Attend my upcoming Free Educational Luncheon Seminar which will be held Wednesday, January 25, 2012, starting at 11:30 AM at the Chico Women’s Club.  I’ll be providing an in-depth discussion covering everything from how your hearing works, to what are the different types of hearing care professionals, to insights about technology solutions for hearing difficulties.  A delicious catered lunch will be served.  There is no cost or obligation to attend, but due to limited seating, reservations are required.  Simply call my office today at 1 (888) 893-1352 ….

Make the Most of Your Hearing – (re) Train Your Brain!

We hear in our ears, but we process and understand sound in our brain. Hearing aids can help a person detect that are no longer in their range of audibility, but they don’t necessarily provide good listening skills. There is a fundamental difference between hearing and listening, and hearing devices alone do not assure good listening. We all know people who have normal hearing but are poor listeners (ok, ok, don’t reference your spouse’s selective hearing!). Hearing requires a functional auditory system that allows sound to be heard, listening requires specific effort and skill, and that can become more difficult when a hearing loss is present.

As technically advanced as modern hearing aids might be, these devices alone cannot ensure listening skills needed for communication. Listening integrates a number of skills including attending, understanding, and remembering. Unfortunately, many of these cognitive skills deteriorate as we age. This may show up as a worsening of short-term memory, or increasing difficulty understanding rapid speech. Modern hearing aids have certainly improved the quality of sound in noisy environments, but they do not eliminate background sounds. People with sensorineural hearing loss have disproportionately difficult time understanding speech in noise. In addition, research shows that a loss of hearing produces physical changes in the auditory pathways of the brain. We now know that when hearing loss deprives parts of the brain of auditory stimulation, neural pathways actually degrade. The old adage of “use it or lose it” is very true with regard to hearing loss- waiting to get hearing aids when you know you have hearing loss is problematic because your brain may not be receiving the kind of stimulation it needs to maintain speech understanding.

Bettie Borton, Au.D. Doctor of Audiology AudiologistWhen people lose confidence in their ability to communicate in noisy social situations, they simply drop out and avoid those environments. While this may save them effort and embarrassment, it ultimately costs them important personal and social contact. Some individuals utilize compensatory strategies that may result in successful hearing aid use. Others, however, are not so fortunate. The need for additional therapy beyond that provided by devices alone is becoming increasingly evident, and is underscored by the fact that individuals with similar hearing loss frequently report a wide range in satisfaction and benefit from their hearing aids.

The good news is a Board Certified Audiologist can optimize your hearing aid hearing experience using a number of methods, strategies and techniques. The hearing healthcare professionals at Doctors Hearing Clinic specialize in developing individualized treatment plans for those struggling with hearing impairment, and can offer the very latest in technologies, as well as the time required to successfully implement them! Have realistic expectations for hearing aids – they’re wonderful devices, but not new ears. Join a self help group to share methods and techniques that are successful for you and others (Montgomery has a Hearing Loss Support Group that meets the second Thursday of each month at the First Methodist Church, 4 PM, free of charge!). And consider new computer software to “train your brain” to listen more effectively!

The great news is that with the help of a skilled Audiologist who routinely offers programs in aural rehabilitation, you or your loved ones can keep listening skills from deteriorating and improve ability to function in noisy situations. When a person injures an arm or leg, everyone recognizes the importance of physical therapy to strengthen adjacent muscles and instruction to optimize function. Similarly, it is likely that hearing devices alone will not produce optimal communication skills unless accompanied by counseling and training.

There are many exercises you can try on your own. Here are three examples:

• Use closed- captioned TV, or record programs using a DVR or TIVO. Watch the show live. Then replay it with closed captioning or by slowing it down.

• Listen to, while reading, audio books.

• Buy two copies of the newspaper. Have your spouse or colleague read the newspaper aloud while you are listening only, and then go ahead and read it yourself. Try this in quiet at first, and then proceed to noisier listening environments.

• Try self-help computer assisted training programs

One such auditory training therapy program designed to help the brain listen, Listening and Communication Enhancement (LACE) uses a computer or DVD. LACE is designed to enhance listening and communication skills, improve confidence levels, and provide communication strategies. The program consists of a variety of interactive and adaptive training tasks for listening to speech in noise, rapid speech, and auditory memory. Besides the immediate feedback given for each task, LACE provides you with a graph depicting daily improvement from the start of the training.

LACE training is conducted in the privacy of your own home at a pace comfortable to you; Doctors Hearing Clinic also offers a computer lab where you can take all or part of the training in their office. Research on thousands of people with hearing loss demonstrates that you can expect on average a 40% improvement of speech comprehension in noisy situations, if you complete the training program.

So if you or someone you love uses hearing devices, take the important step of seeking help from a Board Certified Audiologist to help you develop a comprehensive strategy for hearing and communication skills – train your brain for listening!

You bought new hearing technology, but, you still have difficulty hearing in noise. What’s going on??

“Dr. Gosalia, I just bought a pair of $8500 hearing aids from XYZ in Portland. I was told that I would hear normally in all environments, including restaurants and ball-games. I am less than pleased because I still can’t hear or understand in noise. Did I waste my money?”

Amit Gosalia, Au.D. - Doctor of Audiology, Vancouver, WAThis was a case I dealt with a few months ago. This patient went to a business to purchase hearing aids, and this franchise/chain location set some lofty expectations for the patient. As hearing instrument technology improves, so do patient expectations. Terms such as noise reduction, noise management & directional hearing (along with many other proprietary terms) give the perception that the end-user will not hear background noise, and only hear the person in front of them. Unfortunately and fortunately, this is not true. Below I’ve touched the surface of noise, noise reduction and directivity.

Let’s start with noise. Noise is any disrupting event (in this case, sound) that impedes one’s ability to sense (in this case, hear) a signal (in this case, speech). For the purpose of this post, we’ll concentrate on hearing speech within a noisy environment. A general term and formula that is used in hearing healthcare is Speech-to-Noise Ratio (SNR) which tells us how loud speech is in relation to noise. For example, average speech is 45-55 decibels (dB) hearing speech in a basketball stadium where the crowd is cheering over 90 dB is difficult because the speech is 35-45 dB lower than the noise. This is considered a very low SNR; now compare this to speaking at a normal volume in a quiet library, the SNR will be high making speech much easier to understand. When someone has a hearing loss things change. Without amplification important parts of speech are not heard well, making understanding the person next to you difficult, if not impossible. The natural ability of any person to hear through noise decreases as hearing loss increases. This is a fact that has been well established in research on the human auditory system. Thus, a hearing aid can help make missing pieces of speech more easily heard but it cannot repair one’s ability to hear through noise and find valuable pieces of speech. For this reason, modern hearing aids focus on managing noise and amplifying clean speech.

Hearing instruments can come with or without venting. Vents are holes that are drilled through either the hearing instrument or the earmold for the purpose of letting air and sound travel in and out of the ear canal. The larger the vent, the closer you get to a more natural, open ear. Newer technology has allowed us to keep the ear open with small hearing instruments that rest behind the ear and even some custom molded devices (please see other postings for detailed descriptions of hearing technology). As cute as they may be, if your hearing is not within or near normal limits in the lower frequencies, an open ear device may not be for you.

One advantage of an open ear hearing aid is to allow low frequency sound to escape the ear canal, keeping the user’s voice more natural. When the user complains of hearing their own voice in their head or sounding as if they are speaking in a barrel, it’s usually a phenomenon called occlusion (or ampclusion). Keeping an ear canal open minimizes this effect but also introduces two detrimental issues. First, low frequency environmental sounds will bypass the hearing aid and travel into the ear naturally through the vent. These sounds that bypass the hearing aid are often heard naturally because most hearing losses are minimal in the low-frequencies and greater in the high-frequencies. This also means that the hearing aid is not able to process the sound before it’s heard, so technologies such as noise reduction do not affect low-frequency sounds in the open ear hearing aid.

Secondly, directional microphones will prove less beneficial in the open-ear fitting.2 What this means is that the more open the ear canal, the harder it becomes to hear what’s in front of you. So, theoretically, if our goal is to have the instruments focus more front-facing, the ear canal should not be very open. Note that normal low frequency hearing will be affected by closing the ear canal, and opening the canal with moderate to profound low frequency hearing will result in less hearing in those frequencies.1,2

So, what does this tell us about hearing in noise with amplification? You will hear background noise in noisy environments. You will most likely hear the kids screaming four tables away. You may still have difficulties hearing the person across the table from you. The good news is that with proper hearing aid selection and the correct technology that meets your lifestyle and budget, you’ll hear much better. Only a well trained hearing care professional can make these choices and help you to establish reasonable expectations for better hearing.

“Ms. XX, although the level of technology you purchased is consistent with an Active Lifestyle (in our clinic approx $7500 – $1000 less than the chain!!), you should know that hearing aids only supplement your hearing in those difficult environments. In fact, with normal hearing, I have difficulty hearing at basketball games and certain restaurants as well. Although we can not restore normal hearing, we can help you hear much better in more environments. You will still have some difficulty hearing and understanding in certain environments, but, with some realistic expectations, expert advice, and some auditory retraining, you will find greater success.”

It Doesn’t Really Matter If I Wear My Hearing Aids, RIGHT?

WRONG! According to ScienceDaily (Sep. 20, 2011), mild hearing loss has now been linked to brain atrophy in older adults. Anecdotally, over the course of my 30+ years in private practice as a Board Certified Audiologist, I’ve observed this to be true. But now, more and more research is indicating strong correlation between failure to obtain or use hearing devices and increased problems with understanding speech and cognition.

Bettie Borton, Au.D. Doctor of Audiology AudiologistWe have all heard (or perhaps experienced) the complaint that despite the fact that speech is audible, it’s not understandable. “I hear but I can’t understand” is probably the most commonly voiced concern in my office. So, if someone has hearing loss, if your hearing aids make sounds louder, why doesn’t that solve all hearing related issues? Well, like lots of things in life, it’s just not that simple.

A person’s audiogram (or those little blue X’s and red O’s on the graph of your responses to the “beeps”) tells us a lot, but it does not yield the whole story. Hearing thresholds (or the point at which someone is just barely able to detect sound across the frequency range) are certainly important, but don’t give much information regarding how well someone will understand when speech sounds are made sufficiently loud. Word recognition testing, with and without noise, provides additional information regarding this capability, and as a by-product, an indirect measure of the distortional component inherent to sensorineural hearing loss.

We now have mounting evidence that those who have hearing loss, but fail to get and/or use hearing devices run the risk of depriving their auditory system of sufficient loudness, which in turn results in degradation of the mechanisms responsible for understanding speech. A new study by researchers from the Perelman School of Medicine at the University of Pennsylvania shows that declines in hearing ability may accelerate gray mater atrophy in auditory areas of the brain and increase the listening effort necessary for older adults to successfully comprehend speech. When any one of our senses (smell, taste, sight, hearing, or touch) is changed in some way, the brain reorganizes and adjusts. In the case of those with hearing loss, researchers found that the gray matter density of brain in areas specific to hearing was lower in people with decreased hearing ability, suggesting a link between hearing ability and brain volume.

So, use it or lose it may be the prevailing philosophy. Take heart (and USE those instruments that you have!) According to this study,  early intervention for hearing loss with the consistent use of amplification can slow the progression of speech comprehension difficulty. “As hearing ability declines with age, interventions such as hearing aids should be considered not only to improve hearing but to preserve the brain,” said lead author Jonathan Peelle, PhD, research associate in the Department of Neurology. “People hear differently, and those with even moderate hearing loss may have to work harder to understand complex sentences.”

In two recent research studies, researchers measured the relationship of hearing acuity to the brain, first measuring the brain’s response to increasingly complex sentences and then measuring cortical brain volume in auditory cortex.  Results indicate that older adults (60-77 years of age) with normal hearing for their age were evaluated to determine whether normal variations in hearing ability impacted the structure or function of the network of areas in the brain supporting speech comprehension.

The studies found that people with hearing loss showed less brain activity on functional MRI scans when listening to complex sentences. Poorer hearers also had less gray matter in the auditory cortex, suggesting that areas of the brain related to auditory processing may show accelerated atrophy when hearing ability declines.

In general, research suggests that hearing sensitivity has important consequences for neural processes supporting both speech perception and cognition. Although most the research has been conducted in older adults, the findings also have implications for younger adults, including those concerned about listening to music at loud volumes. “Your hearing ability directly affects how the brain processes sounds, including speech,” says Dr. Peelle. “Preserving your hearing doesn’t only protect your ears, but also helps your brain perform at its best.”

Physicians should monitor hearing in patients as they age, and everyone should have a baseline audiogram performed by a Board Certified Audiologist, looking specifically at speech recognition abilities even in the presence of normal hearing. Patients should talk to their physician or audiologist if they are experiencing any difficulty hearing or understanding speech. If your physician has not referred you for hearing evaluation, take action!

Consumer Protection Laws & Regulations for Hearing Aid Purchases

October 12th, 2011

Here in California – as in many states – purchasers of hearing aids are afforded protections under state laws and regulations administered by the Department of Consumer Affairs (DCA) through the Speech-Language and Audiology and Hearing Aid Dispenser Board (SLPAHADB).

The SLPAHADB was formed on January 1, 2010 by combining the Speech Language Pathology and Audiology Board with the Hearing Aid Dispensers Board.  Previous laws and regulations remain virtually unchanged except that audiologists are no longer required to hold dual licensure for practicing audiology and dispensing hearing aids.

Audiologist & Ear Doctor, Dr. Crystal Chalmers, Chico, CaliforniaThis board’s mission is ensuring the competency and fair practices of hearing aid dispensers.  It does so by providing licensure through testing, ethical guidelines, boundaries for advertising practices, and acts as a vehicle for consumer complaints, ultimately providing enforcement and disciplinary functions.

While political discussion in the media about government intrusion in our lives is a hotbed topic, consumer protection laws are generally an accepted interaction between the citizenry and government.  Who wants to buy poisonous food, cars that don’t run, or housing that collapses in the slightest breeze, to name just a few examples?

Why should it be any different with hearing aids?   Purchasers have a right to expect fair and honest treatment as well as professional expertise from those they seek help.  It could be argued that hearing aid purchasers – many of whom are our senior citizens – should receive an added degree of protection as many of our laws are designed to protect us as we age beyond our more active years, and thereby tend to rely on the care and guidance of those who are younger.

While all the laws and regulations are too lengthy to list here, these are several of the most important.  For the full listings, visit the SLPAHADB website at www.speechandhearing.ca.gov

  • 30 Day Warranty  – The “Song-Beverly Consumer Warranty Act” provides a 30 day warranty on all new and used hearing aids.  If the hearing aid is not specifically fit for the buyer’s particular needs, the device may be returned to the dispenser within 30 days of the of the date of the actual receipt by the buyer or completion of fitting by the seller, whichever occurs later.  If the buyer returns the device the seller must either adjust or replace the device or promptly refund the total amount paid.

It should be noted that while many dispensers advertise things like “30 day risk-free guarantee” they are merely staying within the state mandated minimum trial period of 30 days.  My professional opinion is that for many purchasers, 30 days is too short as it does not allow enough time for the brain to get used to hearing again.  In my practice, I offer a 75 day trial period in order to make certain my patients have all the time they need to be successful.

  • Mail Order & Internet Sales  – California law provides that mail order/Internet hearing aids may only be purchased through a dispenser licensed in California.  The law also states that that when hearing aids are purchased by mail order/Internet, there must be no fitting, selection, or adaptation of the instrument and that the seller must not give any advice with respect to the taking of an ear impression(s). Anyone contemplating this avenue should be aware of potential risks as to work effectively, hearing aids must fit correctly.  If a sale doesn’t involve personal contact between the dispenser and buyer, it is difficult to assume that proper fitting and follow-up care could occur.
  • In-Home Contracts & Cancellation Rights – If you sign a hearing aid purchase contract in your home, federal and state laws allow you to cancel it for any reason by midnight of the third business day after you signed the contract.
  • Advertising Guidelines –  Did you know that in California, hearing aid dispensers are not licensed to perform diagnostic hearing evaluations (only audiologists are licensed to do so) and are therefore not allowed to charge a fee for “testing”?  That is why they advertise “free” tests, BUT they must state that the “test” is “to determine if you could be helped by a hearing aid.”

No one selling hearing aids in California can refer to themselves as a “specialist” without including the title “hearing aid dispenser”, nor can anyone refer to certification by putting a bunch of letters after their name.  For example, this listing: “John Doe, NB-HIS” is unlawful.  The correct listing should be:  “John Doe, Hearing Aid Dispenser, Lic. No. XXXX, NB-HIS, Certified by the National Board of Certification in Hearing Instrument Sciences”

Have you ever received one of those “rebate coupons” that resemble checks as part of a direct mail solicitation?  It is a violation to send those to anyone living in California.

And finally, no California licensed hearing aid dispenser can use the terms “doctor” or “physician” or “clinic” or “audiologist” or any derivation thereof, except as authorized by law.

These are just a few of the consumer protections for purchasing hearing aids.   I urge you to be good consumers by getting the facts and educating yourself about where you stand and whom it is that you are considering doing business with.  You’ve worked hard all your life and deserve to be treated fairly, professionally, and with what is in your best interest  …. Because hearing is a wonderful gift!
