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.)

Hearing is Big Business!

Are you Assisting Employees with Hearing Loss? If not, listen up.

In a 2009 survey of 46,000 U.S. households, the Better Hearing Institute (BHI) determined that over the past generation hearing loss grew at an alarming 160 percent of the U.S. population growth— largely attributable to the aging of the American population. Yet the study found that 60 percent of people with hearing loss are below retirement age, indicating that 16.3 million people with hearing loss were in the U.S. workforce in 2010. In other words, untreated hearing loss has serious consequences for both employers and employees. Untreated hearing loss is costing society and those with the loss millions of dollars annually in lost revenue, productivity, and manpower.

Good hearing is good business.  Given the incidence and prevalence of hearing loss, most businesses will confront this challenge in the context of management’s responsibility and oversight of human resources. So, what can companies do to plan for and address the impact of employee hearing loss?  There are a number of simple steps employers can take to educate employees about hearing loss and to facilitate the use of hearing aids, where needed, that are simple to implement and very cost effective.

Previous research at BHI has shown that 50 percent of people with untreated hearing loss have never had their hearing checked by an audiologist and lack sufficient information to know whether they need to take action to correct it. Company owners and human resource professionals can help employees understand if they need treatment by:

 

  • Educating employees regarding the impact of untreated hearing loss on quality of life.
  • Encouraging employees to have their hearing screened on an annual basis, and providing opportunities for them to do so.

Employers can create a corporate climate where hearing loss is recognized so those with hidden hearing loss feel more comfortable. Here are some suggestions:

  • Avoid noisy restaurants as meeting locations.
  • Summarize meeting minutes in writing to be sure that those with hearing issues are clear on the outcome of the meeting.
  • Provide easy accommodations, such as moving an employee’s desk away from noisy hallways, machines, or air conditioning and heating vents, or installing a phone that amplifies high frequencies.
  • Build work environments that facilitate better hearing by choosing cubicles with noise-absorbent materials and equipping meeting rooms with an inductive loop that creates a wireless zone for hearing aids with telecoils, headsets or microphones.

In many cases, hearing aids can help protect employees from being at a competitive disadvantage with peers. Organizations can encourage the use of hearing devices, when needed, by participating with a private practice in Audiology to contract for the provision of services, group discounts, hearing devices, and more! Audiologists can design and implement screening programs (on and off site), as well as effective follow up scenarios to assist employees with managing hearing loss if it is identified.

Companies can also encourage employees to purchase hearing aids using pretax medical flexible spending account funds. In Montgomery, Doctors Hearing Clinic offers just such an option through their BHP program , and the good news is that it is FREE to employers, as well as employees and their families. This Better Hearing Program (BHP) offers free screenings, group discounts on hearing devices, in-service educational presentations, and a host of other hearing related employment benefits.

If you’re currently employed, encourage your employer to seek offerings for the provision of hearing healthcare services, and remember, these services can often be contracted with local audiology practices. If you’re an employer in the Tri County region and don’t currently offer a hearing healthcare package, the program at Doctors Hearing Clinic is an example of what is available to your company. This FREE array of benefits for your staff and their families, offers great value in hearing healthcare at no cost to you or your employees!

So start the 2012  business year out right. By encouraging employees to treat hidden hearing loss rather than hide it, an employer creates a win-win situation by ensuring that the loss of hearing does not interfere with job performance, productivity, safety, or the employee’s career or quality of life on or off the job.

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.

What’s the Best Hearing Aid?

“What’s the best hearing aid?” As an Audiologist, I’ve heard that question so many times. To successfully answer that question, perhaps the very first thing I need to do is modify it slightly ~ “What’s the best hearing aid for you?” An important concept to keep in mind when exploring today’s vast array of options for hearing devices is that what’s right for you may not be right for someone else, and vice reverse. The decision regarding which type of hearing instrument technology will sound and perform the very best will be largely dependent on you, your lifestyle, budget, and listening needs. These parameters tend to be highly variable from person to person, so let’s take a closer look.

Not all hearing losses can be correctly fit with the same style or type of device. This is very evident when fitting those with precipitous loss in the high frequencies.  High frequency deficits are the most common configuration of hearing loss, and respond best to open fit technology. This type of device leaves your ear canal open, ensuring that the sound of your own voice is normal and pleasant. Conversely, fitting those with high frequency loss with conventional “in the ear” devices can have catastrophic results in terms of patient satisfaction. Have hearing instruments that you or your loved one are not using? It may be resultant from the units being the wrong style for the loss! High quality open fit technology has been available for a relatively short period of time, and many of those whose instruments were purchased more than 5 years ago may not have had access to those devices.

What about some of the new “fancy stuff”, like Blue Tooth technology? Is that for you? Many of my patients are not familiar with Blue Tooth, but it can open up a world of ancillary devices and couplings for your hearing devices. For example, if you use Blue Tooth enabled hearing aids, you can wear a “streamer” around your neck, and answer your cell phone hands free through your hearing aids! With the new cell phone use restrictions now in place in Montgomery, that can be a really handy feature. It’s also possible to listen to your TV or IPod directly through your hearing instruments with this technology, or use a special microphone to make conversations with your significant other in a noisy car or restaurant much easier. Other technologies to consider are remote controls, assistive listening devices like amplified phones or doorbell alerts, or FM devices to help with performance in a classroom or job environment. However, if you don’t want or need such technologies, don’t pay for them!

What kind of lifestyle do you have? If you are still working, it’s likely that you are in highly variable listening environments, or your profession demands auditory accuracy (and most jobs do!). Those who lead very active lifestyles need to consider today’s high end technology, with plenty of noise reduction capability. On the other hand, if you’re retired, living alone, and seldom go to restaurants or parties,  simpler, more basic noise reduction features will suffice – and cost less! If you are the type of person who “wants the best of everything” then there are plenty of high end technologies to wow you (and your friends and family). Don’t overbuy, but do be honest with your Audiologist about your listening needs. If you aren’t you may be disappointed with your hearing devices.

Finally, as self-serving as this might sound, perhaps the only honest and comprehensive answer to the question above is “a hearing device recommended and provided by an exceptionally skilled and dedicated Audiologist.” Sometimes that’s not the answer folks are looking for. I have patients tell me “it’s all about price” or request a specific brand because a friend or relative was successful with a particular device. Hearing aids are a big investment with the potential for providing a big improvement in the quality of your life. People with hearing impairment need a competent and caring Board Certified Audiologist who will go the extra mile to provide them with solutions custom-tailored to their own unique hearing loss and listening situations. As critical as the various aspects of technology may be to the hearing aid industry, it is ultimately the professional who is the decisive factor in guiding patients to satisfaction and benefit with hearing devices.

Note: Doctors Hearing Clinic was recently named Best of 2011 Hearing Healthcare Professionals by The Hearing Review, and was Dr. Borton and her staff were the only clinic in Central Alabama to receive this award. This recognition was provided to only 165 hearing healthcare clinics across the United States.

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!

Can I Prevent My Hearing Loss From Getting Worse?

Bettie Borton, Au.D. Doctor of Audiology AudiologistWhen I diagnose patients with a loss of hearing, they usually want to know if there is any way they can stop the progression of the loss. Common sense (and a large body of research) tells us that hearing loss tends to get worse as we get older, but each case is unique. In many cases, hearing is stable for many years. In others, the hearing loss progresses relatively rapidly.

One of the most important things that all adults over the age of 50 need to do is to have an audiological evaluation that will establish their baseline hearing, and keep that on file with their primary care physician and with their health records kept at home. Getting a comprehensive audiometric  by a Board Certified Audiologist ensures that you have been evaluated by a professional who has the most training for this purpose, and ascribes to the highest ethical, practice,  and continuing education requirements available. Why is it so important to have this baseline? Well, if your hearing changes, it will be much easier to gauge the rate of progression of the loss if you have clearly established a “starting point”, and have annual re-evaluations to document any shift in thresholds. And remember, documenting that starting point could be very important –No one wants to borrow trouble, but  don’t forget that  17% of all of those involved in motor vehicle accidents with air bag deployment have permanent sensorineural hearing loss as a result! That could be difficult to prove in a court of law if you haven’t had a recent hearing test.

Noise is a leading cause of hearing loss, and hearing loss from noise exposure is usually preventable. Both the level of the noise and the length of time you’re exposed to it determine if a noise will cause damage to your hearing. A good rule of thumb is: if you have to raise your voice to be heard by someone standing three feet away, the noise around you could be damaging.  Everyday sounds, such as music, power tools, or a lawn mower, have been shown to cause hearing damage.

Visit a local hearing center for advice regarding the best options for ear plugs or other noise protection to wear during these activities and get your hearing checked on a a regular basis.  Your hearing professional can compare your exams over time to determine if your hearing loss is worsening. If a significant change is noted, your hearing professional may refer to you to an ear doctor for further evaluation.

 

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.”

A gentleman called yesterday and wondered if one of our audiologists would please make an impression of his ear. He found a hearing aid and wanted to “whittle on it” to make it fit his ear better. My first reaction (after “YUCK!”) was Why in the world would anyone want to wear a hearing aid that was customized for another person’s ear and hearing loss?!?!

Helen Hallenbeck, Audiologist Missoula, MTWas it a fundamental lack of understanding of the complexities of hearing loss and the insidious impact that loss has on relationships, communication patterns and lifestyle? Was it financial limitations? It takes an average of 7 years from the moment a person realizes they have a hearing loss until that person decides to get help. Throughout that period of emerging awareness, the person with a hearing loss is bombarded with mixed marketing messages. “Our Amazing Hearing Aids get rid of ALL unwanted background noise!” “Our Amazing Hearing Aids are INVISIBLE!” Our Amazing Hearing Aids will let you hear ONLY what you want to hear!”. In addition to the inexcusable exaggeration of the capabilities of any hearing technology, the hearing aid companies lure people in with FREE! everything.

Is it any wonder, when a person is finally ready to make the deeply personal and incredibly important  investment, that they fundamentally misunderstand what it is they are investing in and who it is they are investing with? The gentleman’s request for an ear impression so he could make his own hearing aid should not come as a surprise. The  hearing industry has painted themselves into a corner with salesmanship and bottom-dollar marketing. As a result the industry has devalued it’s very existence.

The truth is, hearing loss is complicated, frustrating and has a profound negative impact on the lives of the people that are affected. It is time the industry began to address the PERSON with the hearing loss. Today’s hearing technology is truly amazing and an appropriate solution can be found to fit within virtually any budget. But unless that technology has been chosen specifically for the individual, with all of his needs, desires, concerns, question and fears having been accounted for and carefully considered, then the technology has been wasted.

Let us each  work to make rigorous diagnostics, counseling, education, prevention and rehabilitation the expectation of the consumer.  Let’s stop the transactional process of hearing care that so dominates this industry and start humanizing what is truly a disability.

Auditory training is a term you will probably only hear in an audiology office or perhaps a school. But it is important for people with hearing loss to know that they can train their brain to hear and listen. Our brain is always searching for sounds whether or not we focus on the sounds and this is called “hearing”. Attending to and focusing on a sound, causing more parts of the brain to react is called “listening.” People who have hearing loss often stop working at listening because it is too difficult and causes fatigue or frustration. Unfortunately this leads to more communication problems due to the combined effect of hearing loss and diminished listening skills. Though anyone can benefit from the practice of using and strengthening listening skills it is more important for those who are hard of hearing.

When it comes to hearing loss and hearing aids, most hearing aid users look to the device to make communication better and though hearing aids can improve hearing, they cannot improve listening. Instead, hearing aid users should strive to be “patients of hearing health care” and look for solutions to improve hearing and listening. This can be accomplished by using any and all devices needed to support hearing as well as therapy and exercises for listening. The highest level of satisfaction with hearing aids comes from following the audiological recommendations in full and accepting that learning to hear and listen again is a process that requires motivation and time. Research in audiology reveals over and over again that hearing care is not a simple thing. The audiology degree is a testament to this fact. For example, an audiology student will spend 8 years in college, earn two or more higher education degrees and perform thousands of clinical hours with patients. Still many people price check for hearing aids believing they are making a technology purchase instead of looking at the professional behind the technology and the service that comes with learning to hear and listen.

I’ve been on both “sides of the fence” so to speak. I am a hard of hearing consumer and user of hearing aids. I grew up with hearing loss in both ears and have used hearing aids in both ears as long as I can remember. I am also a doctor of audiology and the owner of HearWell Center in Forest Hills (independently owned private practice). Educating patients is very important to me and I invite you to visit our website for more information.

Hearing with Only One Ear (Unilateral Hearing Loss)

Hearing loss in one ear can result from several disorders or injuries:

  • Bacterial  infections
  • Head injury
  • Vascular (blood supply) problem
  • Meniere’s disease
  • Viral infection (herpes)
  • Acoustic or 8th nerve tumor
  • Acoustic trauma (sudden loud noise to one ear)

Patients who suffer a severe to profound hearing loss in one ear report no comprehension difficulty in quiet, one-one-one conversations.  However, understanding conversation in less than ideal listening situations is severely compromised.  These include noisy areas such as restaurants,  group conversations and reverberant areas such as churches, gyms, and indoor swimming pools.

Why are these areas so challenging for those with unilateral deafness?  Your ears individually and collectively gather acoustic information and relay those signals to the auditory reception centers in your brain.  With only one ear collecting information, the auditory centers are starved for the complete acoustic picture normally provided by two ears.  When this information is lacking, a number of things  happen that impair your ability to organize and make sense of speech.

Joan D'Alessandro, Au.D. - Doctor of Audiology, Paoli, PennsylvaniaHead Shadow Effect

When a sound occurs toward the deaf ear, the arrival of that sound at the hearing ear is partially blocked by your head, commonly known as the head shadow effect.  The sounds most easily blocked are the higher pitches which are absolutely  necessary for accurate perception of the voiceless consonant sounds of speech, the s,c,f,t,p,ch and  sh sounds.  These consonants allow us to tell the difference between words like teach versus feast and distillery versus facility. This word discrimination ability is compromised by hearing with only one ear because of the head shadow effect.

Localization Ability

Your brain needs well-balanced sound information from both ears for you to be able to easily pick out the direction from which a sound originates.  Both a sound’s time of arrival (it arrives a few milliseconds faster at the ear closest to the sound) and its intensity or loudness (louder for the ear closest to the sound) are cues that your brain uses to locate the source of a sound.  When you have only one ear, all sounds seem to be coming from the side of the  good ear, even when originating from the bad ear side.  So someone with hearing in only one ear lacks the instantaneous locating cues of time and intensity.  If someone calls your name outdoors, you have to turn your head around to locate the source and it may take several repetitions to accurately pinpoint the source.

Sound Summation and Noise Squelch

To your brain, one ear + one ear = three!  A sound which is barely audible at 20 feet away with only one ear, is easily audible at 30 feet when two ears are listening.  This is called the binaural summation effect and is the result of the two hearing nerves crossing many hundreds of times before the information reaches the cortex.  This crossing or decussation results in the enhancement of sound, so softer sounds become audible.

In addition, this neural sharing contributes to an advantage, known as binaural squelch, when listening in background noise.  This ‘squelch’ provides 3 decibels more signal than noise, also known as the signal –to- noise ratio or SNR.  Even though three  decibels may not seem like much, the decibel is a logarithmic function much like the Richter scale for earthquake measurement.   For every 3 decibels, sound power actually doubles. So three decibels extra is a significant amount and allows for easier understanding in noisy situations.

Solutions for Those with Only One Hearing Ear

The traditional hearing aid solution for unilateral hearing loss has been the use of a CROS hearing aid. The acronym stands for Contralateral Routing of Sound and employs a unit on the dead ear which contains a microphone to pick up sounds arriving on that dead side.  Those sounds are then transmitted wirelessly to a receiver unit on the good side. The sounds from the dead side are then routed into the good ear.

This CROS type aid prevents the head shadow effect but does nothing for localization ability and does not provide binaural summation or squelch.

If the hearing loss is in the  severe category, a traditional hearing aid either in a behind-the-ear(BTE) or in-the-ear style  can be fit.  As with all hearing aids fittings there is an accommodation period during which the patient learns to use the acoustic information from the damaged ear.  The sooner the fitting is done, the more likely the patient will be a successful hearing aid user.

A fairly recent surgical solution for single-sided deafness (SSD) is the implantation of a BAHA or Bone-Anchored Hearing Aid.  This surgical implant uses bone conduction to send sounds from the bad ear side to the good ear via an implant with a microprocessor that adheres to a magnet under your scalp.  The processor is detachable for showering, etc., and is easily hidden underneath your hair.  Again, the BAHA does not accomplish true binaural hearing but does lessen the head shadow effect and some recipients do notice improved localization ability after use of the BAHA for some time.

Our brains are wired to receive information from both ears. Loss of hearing in one ear is a significant handicap with which many people cope through the use of CROS type hearing aids, BAHA implant and positioning themselves  to maximize the best sound reception to the hearing ear.
