Hearing, Hearing Loss and Hearing Aids: Issues and Answers

Hearing loss occurs to most people as they age. Hearing loss can be due to aging, exposure to loud noise, medications, infections, head or ear trauma, congenital or hereditary factors, disease processes and many other causes. The vast majority of hearing problems do not require medical or surgical intervention. Some 90 to 95 percent of all cases of hearing loss can be corrected with hearing aids.

There are some 28 million people in the USA with hearing loss. Hearing loss is the single most common birth "defect" in America. Approximately one third of all seniors aged 75 years and older have significant hearing loss. About 14 percent of all people aged 45 to 64 years have demonstrable hearing loss. Hearing loss negatively impacts quality of life, personal relationships and of course, your ability to communicate.


You may have hearing loss if...

  • You hear people speaking but you have to strain to understand their words.
  • You frequently ask people to repeat what they said.
  • You dont laugh at jokes because you miss too much of the story or the punch line.
  • You frequently complain that people mumble.
  • You need to ask others about the details of a meeting you just attended.
  • You play the TV or radio louder than your friends, spouse and relatives.
  • You cannot hear the doorbell or the telephone.
  • You find that when people look directly at you while they speak to you, it makes it easier to understand.

If you have any of these symptoms, you should see an audiologist to get an "audiometric evaluation." An audiometric evaluation (AE) is the term used to describe a diagnostic hearing test, performed by a licensed audiologist. An AE is not just pressing the button when you hear a "beep." Rather, an audiometric evaluation allows the audiologist to determine the type and degree of your hearing loss, and it tells the audiologist how well or how poorly you understand speech. After all, speech is the single most important sound we listen to and the ability to understand speech is extremely important. Your ability to hear and understand speech in quiet and in noisy situations are important indicators, and they can be accurately tested by your audiologist. The AE also includes a thorough case history (interview) as well as visual inspection of the ear canal and eardrum. The results of the AE are also useful to the ear, nose and throat doctor, in the event the audiologist concludes your hearing problem may be treated with medical or surgical alternatives.

Written hearing tests, "dial a hearing test" and other online hearing tests are not 100% accurate, and are certainly not diagnostic, but they may be utilized as screening tools. These screenings are usually free and can be scored within a few seconds. Written hearing screenings may point the patient (or consumer) in a particular direction and may help validate that a hearing problem exists.


An audiologist is a healthcare professional who has earned a masters and/or doctoral degree in audiology. Audiology is essentially the science of hearing, as it applies to humans. The audiologist must be licensed as an audiologist to practice audiology. In the profession of audiology, the masters degree was the accepted "clinical" degree for almost 50 years. However, the profession has undergone a transition (as of the mid-1990s) and the doctorate will soon be the entry-level requirement to practice audiology. The Au.D. (Doctor of Audiology) is the designation of the professional doctorate in audiology and is issued exclusively by regionally accredited universities and colleges. There are other doctoral degrees that have been earned and utilized by audiologists to date, such as the Ph.D. (still highly sought by researchers and academicians), the Sc.D. and the Ed.D.

Audiologists work in a variety of settings including hospitals, schools, clinics, universities, rehabilitation facilities, cochlear implant centers, speech and hearing centers, private audiology practices, hearing aid dispensing offices, hearing aid manufacturing facilities, medical centers, as well as otolaryngology (ENT physician) offices.

Although the vast majority of hearing problems do not require medical or surgical intervention, and in fact, some 90 to 95 percent of all cases of hearing loss can be corrected with hearing aids, audiologists are clinically, academically and professionally trained to determine which hearing losses do need medical referral. As a licensed healthcare provider, the audiologist appropriately refers patients to physicians when the history, physical presentation, or the results of the audiometric evaluation (AE) indicate the possibility of a medical or surgical problem. Many audiologists also dispense (sell and service) hearing aids and related assistive listening devices for the telephone, TV and special listening situations.


Otolaryngologists (also called ear-nose-and-throat, or ENT doctors) are physicians who have advanced training in disorders of the ear, nose and throat. Otologists or neurotologists are physicians who in addition to their ENT requirements, continued their specialized training for an additional year or more in the diagnosis and treatment of disorders of the ear. Otolaryngologists, neurotologists and otologists are the physicians who typically treat disorders of the ear requiring medical or surgical solutions.


The hearing aid specialist has training in the assessment of patients who specifically seek rehabilitation for hearing loss. The hearing aid specialist is licensed or registered to perform basic hearing tests and can sell and service hearing aids and related products.


Results of the audiometric evaluation are plotted on a chart called an audiogram. Loudness is plotted from top to bottom. Frequency is plotted from left to right. Hearing loss (HL) is measured in decibels (dB) and is described in general categories (below). Hearing loss is not measured in percentages. Of course we have all heard people speak about a "50 percent hearing loss," but that is a qualitative or subjective statement, it is not scientific and it has very little meaning. Thinking of hearing loss in terms of percentage is a little like thinking about vision in terms of percentage!

The general hearing loss categories used by most hearing professionals are as follows:

Normal hearing (0 to 25 dB HL)
Mild hearing loss (26 to 40 dB HL)
Moderate hearing loss (41 to 70 dB HL)
Severe hearing loss (71 to 90 dB HL)
Profound hearing loss (greater than 91 dB HL)


The external and the middle ear conduct sound. When there is a problem in the external or middle ear, a conductive hearing impairment occurs. When the problem is in the inner ear, a sensorineural loss is the result. Difficulty in both the middle and inner ear results in a mixed hearing impairment (conductive and sensorineural impairment). Central hearing loss has more to do with the brain than the ear, and will be discussed only briefly.

Conductive hearing loss occurs when sound is not conducted efficiently through the ear canal, eardrum, or tiny bones of the middle ear, resulting in a reduction of the loudness of perceived sound. Conductive losses may result from earwax blocking the ear canal, fluid in the middle ear, middle ear infection, obstructions in the ear canal, perforations (hole) in the eardrum membrane, or disease of any of the three middle ear bones.

A person with conductive hearing loss may notice their ears seem to be full or plugged. This person may speak softly because they hear their own voice loudly. Crunchy foods, such as celery or carrots, seem very loud and this person may have to stop chewing to hear what is being said. All conductive hearing losses should be evaluated by an audiologist and a physician to explore medical and surgical options.

To demonstrate a conductive hearing loss, gently and safely close your ears with your fingers. This will give you the feeling of a conductive hearing lossyoull feel plugged-up, and youll feel a little hearing impaired. Interestingly, some people may tell you they dont need hearing aids because they ONLY have a 30 decibel hearing loss. However, assuming you have normal hearing, when you plug your ears with your fingers, youll experience approximately a 25 decibel hearing loss and youll quickly realize that going through your day with that much hearing loss is quite irritating and disconcerting!

Sensorineural hearing loss is the most common type of hearing loss. More than 90 percent of all hearing aid wearers have sensorineural hearing loss. The most common causes of sensorineural hearing loss are age related changes and noise exposure. Sensorineural hearing loss may also result from disturbance of inner ear circulation, increased inner fluid pressure or from disturbances within the hearing nerve. Sensorineural hearing loss is also called "cochlear loss" and "inner ear loss" and is commonly called "nerve loss." Years ago, many professionals thought there was nothing that could be done for sensorineural hearing loss -- that is absolutely incorrect!!! There are many excellent options for patients with sensorineural hearing loss. People with sensorineural hearing loss typically report they can hear people speaking, but they cant understand what theyre saying. People with sensorineural hearing loss also complain that "everyone mumbles." They also usually hear better in quiet places and may have difficulty understanding what is said over the telephone.

Central hearing impairment occurs when auditory centers of the brain are affected by injury, disease, tumor, hereditary, or unknown causes. Loudness of sound is not necessarily affected, although understanding of speech, also thought of as the "clarity" of speech may be affected.

The audiologist and the physician work collaboratively to determine if hearing loss is "sensorineural" or "central."


There are many styles of hearing aids. The type and degree of hearing loss, power requirements and options, manual dexterity abilities, cost factors, and cosmetic concerns are some of the factors that will determine the exact hearing aid style the patient will use. The most common styles are listed below:

ITE: In-The-Ear units are probably the most comfortable, the least expensive and the easiest to operate. They are also the largest of the custom made styles.

ITC: In-The-Canal units are a little more expensive than ITEs. They require good dexterity to control the volume wheels and other controls on the faceplate and they are smaller than ITEs.

MC: Mini-Canals are the size between ITC and CIC. A mini canal is a good choice when you desire the smallest possible hearing aid while still having manual control over the volume wheel and possibly other controls.

CIC: Completely-In-the-Canal units are the tiniest hearing aids made. They usually require a "removal string" due to their small size and the fact that they fit deeply into the ear canal. CICs can be difficult to remove without the pull string. CICs do not usually have manual controls attached to them because they are too small.

BTE: Behind-The-Ear hearing aids are the largest hearing aids and they are very reliable. BTEs have the most circuit options and they typically offer much more power than custom made units. BTEs are the units that rest on the back of your ear. They are connected to the ear canal via custom-made plastic tubing. The tubing is part of the earmold. The earmold is custom made from an ear impression to perfectly replicate the size and shape of your ear.

PAC: Post-auricular-canal instrument. This is a new hearing aid design which physically separates the processor from the receiver/speaker. This design offers comfort and acoustic options as the tiny processor is placed behind the ear, and the receiver/speaker is placed deep in the ear canal.


All custom made hearing aids and earmolds are made from a "cast" of the ear. The cast is referred to as an ear impression. The hearing professional makes the ear impression in the office. It takes about 10 to 15 minutes. The audiologist places a special cotton or foam dam in the ear canal to protect the eardrum, and then a waxy material is placed in the ear canal. When the material hardens (about 5 to 10 minutes later) the wax cast, along with the dam are removed from the ear canal. Often, the ear canal will be "oily" after the impression is removed. This is normal. The oil comes from the earmold material and prevents the material from sticking to the skin.

Tell the audiologist before the ear impression is obtained if you are allergic to plastic or dyes!


Hearing aids work very well when fitted and adjusted appropriately. Hearing aids amplify sound! The left and right hearing aids will probably not fit exactly the same and they probably wont sound exactly the same. You might find you like one hearing aid better than the other Nonetheless, hearing aids should be comfortable with respect to physical fit and sound quality. Hearing aids do not restore normal hearing and are not as good as normal hearing. You will be aware of hearing aids in your ears. Until you get used to it, your voice will sound "funny" when you wear hearing aids. Hearing aids should not to be worn in extremely noisy environments. Some hearing aids have features that make noisy environments more tolerable, however, hearing aids cannot completely eliminate background noise. Background noise is a real bother for many people. I encourage you to speak with your hearing healthcare professional about options that significantly reduce background noise, such as directional microphones, LINK-IT and FM systems, they work very well and I encourage their use.


There are essentially three levels of hearing aid technology. I refer to them as analog, digitally programmable, and digital.

  1. ANALOG technology is the technology that has been around for many decades. Analog technology is basic technology and offers limited adjustment capability. It is the LEAST expensive and the least flexible. I rarely recommend analog technology.
  2. DIGITALLY PROGRAMMABLE technology is the "middle grade" technology. Digitally programmable units are actually analog technology, but they are digitally controlled by the computer in the office to adjust the sounds of the hearing aid.
  3. DIGITAL technology is the most sophisticated hearing aid technology. Digital technology gives the audiologist maximum control over sound quality and sound processing characteristics. There are qualitative and quantitative indications that digital instruments do outperform digitally programmable and analog hearing aids. Digitals are not perfect, but they are very good. I ALWAYS recommend digital hearing aids, unless there is an overwhelmingly compelling reason to recommend a lesser product.

DIGITAL HEARING AIDS:The term DIGITAL is used so often today, it can be confusing. When the term "digital" is used when referring to hearing aids, it generally means the hearing aid is 100% digital. In other words, the hearing aid is indeed a "complete computer". 100% digital hearing aids have been commercially available since the mid-1990s and they are wonders of modern technology. 100% digital hearing aids can process sound using incredibly fast speeds. Interestingly, most 100% digital hearing aids have some analog components, such as the microphone and the receiver. 100% digital hearing aids transform analog information into a digital signal and process the sound to maximize the speech information you want to hear, while minimizing the amplification of sounds you do not want to hear.

Digital technology is tremendous and it allows the audiologist maximal control over the sound quality and loudness of the hearing aid. Importantly, digital technology allows the audiologist to tailor or customize the sound of your hearing aids to what you need and want to hear. In summary, if you want the best technology -- get 100% digital hearing aids.


When you wear hearing aids for the first time, youll probably notice your voice sounds funny! Youll hear your voice amplified through the hearing aid and some people describe this sensation as feeling "plugged up" or hearing your voice echoing. This is normal and will usually go away in a few days after you have given yourself a chance to get accustomed to your new hearing aids and learned to adjust the volume controls. However, there are adjustments the audiologist can make to relieve these symptoms, should they persist beyond the first few days, or it they are intolerable and need to be addressed immediately.


People learn at different rates. Some people need a day or two to learn about and adjust to their hearing aids, most need a few weeks and some may need a few months. There is no perfect way to learn about hearing aids. I usually recommend you wear hearing aids for a few hours the first day and add about an hour a day for each following day. Do not try to set an endurance record! Over time you will increase the amount of time you wear hearing aids. Eventually you will wear the hearing aids most of your waking hours. It is recommended you interact with people most familiar to you during your first few days. Start off with your hearing aids in a favorable listening environment (such as one-on-one conversations in quiet) and work towards more difficult listening situations. Let your friends and family know youre using your new hearing aids.

Please do NOT wear them to a cocktail party or restaurant during the first few weeks, while thinking "this will be a good test." It will absolutely not be a good test it will be very difficult! You should not wear hearing aids in noise until you are very accustomed to them!

Helpful Steps to Learning to Use a Hearing Aid:

  1. At first, wear the hearing aids in your own home environment.
  2. Wear the hearing aids only as long as you are comfortable wearing them.
  3. Accustom yourself to the use of the hearing aids while conversing with just one other person.
  4. Do not strain to catch every word, even people with normal hearing do not hear every word!
  5. Do not be discouraged by background noise.
  6. Practice locating the source of the sound by listening only.
  7. Increase your tolerance for loud sounds SLOWLY.
  8. Practice learning to discriminate different speech sounds.
  9. Listen to something read aloud, "books on tape" are available at your library.
  10. Gradually extend the number of persons with whom you speak.
  11. Gradually increase the number of situations in which you use your hearing aids.
  12. Take part in an organized course of aural rehabilitation, see your audiologist to learn about these courses.

HEARING and VISION and COMMUNICATION:To maximally communicate, you need to hear from both ears (binaural hearing) and you need to use your eyes and ears together. You will not communicate well using your hearing aids alone. To facilitate optimal communication, you need to pay attention to the speakers gestures and facial expressions! To maximize communication remember to watch the person speaking, reduce the distance between the speaker and the listener, reduce or eliminate background noise and use good lighting. If someone is speaking to you from across the room while the TV is on and while youre doing the dishes, it will be very difficult to adequately communicate, despite fantastic hearing aids!


Basically, if you have two ears with hearing loss, and if both ears could benefit from hearing aids, you need two hearing aids. It is important to realize there are no "normal" animals born with only one ear. Simply stated, you have two ears because you need two ears. If you try to amplify sound in only one ear, you cannot expect to do very well. Even the best hearing aid will sound "flat" or "dull" when worn in only one ear.

Assuming you have two ears that hear about the same, you can do a little experiment at home to better understand how important binaural hearing is:

First, gently close just one ear, by simply pressing the little fleshy part in the front of your ear canal (the tragus) into your ear canal -- a little. Do not apply pressure, do not hurt yourself. Just close the ear canal to eliminate sound from entering the ear. The idea is to close that ear for about ten minutes while you watch TV or listen to the radio or speak with your spouse. Then, after a full ten minutes, remove your finger. What an amazing difference!

There are many advantages associated with binaural (two ear) listening and importantly, there are problems associated with wearing only one hearing aid -- if you are indeed a candidate for binaural amplification.

Localization (knowing where the sound came from) is only possible with two ears and it is just about impossible with one ear. Localization is not just a sound quality issue; it may also be a safety issue. Think about how important it is to know where warning and safety sounds (sirens, screams, babies crying, etc) are coming from. Using both ears together also impacts how well you hear in noise because binaural hearing permits you to selectively attend to the desired signal while "squelching" or paying less attention to undesired sounds -- such as background noise.

Binaural hearing allows a quality of "spaciousness" or "high fidelity" to sounds, which cannot occur with monaural (one ear) listening. Understanding speech clearly, particularly in challenging and noisy situations is much easier while using both ears. Additionally, using two hearing aids allows people to speak to you from either side of your head not just your "good" side!

People cannot hear well using only one ear. There are studies in the research literature that show that children with one normal ear and one "deaf" ear are ten times more likely to repeat a grade when compared to children with two normally hearing ears. Additionally, we know that if you have two ears with hearing impairment and you wear only one hearing aid, the unaided ear is likely to lose word recognition ability more quickly than the ear wearing the hearing aid.


One concern with all new hearing aids is the physical fit. Hearing aids need to be comfortable, not too tight and not too loose, they should fit just right. Do not wear the hearing aids if they cause discomfort or irritations. Do call your audiologist to schedule an appointment to remedy the problem as soon as possible. Do not wear hearing aids if they are uncomfortable.


Virtually all patients wearing hearing aids complain about background noise at one time or another. There is no way to completely eliminate background noise.

Remember, when you had normal hearing there were times when background noise was a problem. It is no different now, even with properly fit hearing aids! The good news is there are circuits and features that help to reduce (or minimize) background noise and other unwanted sounds. In fact, there are research findings that clearly show that digital hearing aids with particular circuits, FM options, and directional microphones can effectively reduce background noises. Please speak with your audiologist about this.

Many early digitally programmable (and even some digital) circuits, which claimed to reduce or eliminate background noise, actually filtered out low frequency sounds. This indeed made the sounds appear quieter, however, not only was the background noise made quieter, but so too, was the speech sound.

Newer ways to reduce background noise are based on timing and amplitude cues and other complex noise processing strategies, which 100% digital hearing aids can process. These methods work, but are not perfect. Directional microphones are available and are useful as they help to focus the amplification in front of you, or towards the origin of the sound source. Directional hearing aids can offer a better signal-to-noise ratio in difficult listening situations by reducing the noise from the sides or behind you. In most 100% digital hearing aids, the noise control features help make noise more tolerable.

The best and most efficient way to eliminate or reduce background noise is through the use of FM technology. Please speak with your audiologist about this.


More than 75 percent of all hearing aid repairs are due to moisture and earwax accumulating in the hearing aid. The vast majority of these repairs are 100 percent preventable. It is extremely important to clean the entire hearing aid every time it is removed from your ear by wiping and brushing it. To better protect your investment, use a DRY-AID kit every night! Electronic dry-aid kits are the best. They include a germicidal light that kills most bacteria and other germs. They also have desiccants to absorb moisture and fans to circulate air around the internal components of the hearing aid. Get in the habit of cleaning the hearing aid after each use and keeping the hearing aid in the dry-aid kit at night. The hearing aid is electronic and moisture is the enemy! Preventive maintenance is the key to trouble free, long life from a hearing aid. A well maintained hearing aid can easily last 5 to 7 years, maybe longer.

All batteries are toxic and dangerous if swallowed. Keep all batteries (and hearing aids) away from children and pets. If anyone swallows a battery it is a medical emergency and the individual needs to see a physician immediately.

One question often asked is "How long does the battery last?" Typically they last 7-14 days based on 16 hours per day use cycle. Batteries are inexpensive, costing less than a dollar each. Generally, the smaller the battery size, the shorter the battery life. The sizes of hearing aid batteries are listed below along with their standard number and color codes.

Size 5: RED
Size 10 (or 230): YELLOW
Size 13: ORANGE
Size 312: BROWN
Size 675: BLUE

Today's hearing aid batteries are "zinc-air." Because the batteries are air-activated, a factory-sealed sticker keeps them "inactive" until you remove the sticker. Once the sticker is removed from the back of the battery, oxygen in the air contacts the zinc within the battery, and the battery is "turned-on". Since many of today's automatic hearing aids do not have "off" switches, removing the battery from the hearing aid circuit, by opening the battery door, when not in use, assures the device is turned off. Zinc-air batteries have a "shelf life" of up to three years when stored in a cool, dry environment. Storing zinc-air hearing aids in the refrigerator has no beneficial effect on their shelf life. In fact -- quite the opposite may happen. The cold air may actually form little water particles under the sticker. Water is made of oxygen and hydrogen. If the water vapor creeps under the sticker, oxygen may contact the zinc and the battery could be totally discharged by the time you peel off the sticker! Therefore, the best place to store batteries is in a cool dry place, like the back of your sock drawer, not the fridge!

You may have certain communication needs that cannot be solved by just using hearing aids. These situations may involve telephone, radio, television, or the inability to hear the door chime, telephone bell, and alarm clock. Special devices have been developed to solve these problems. Like hearing aids, assistive listening devices and alerting devices make sounds louder. Typically, a hearing aid makes all sounds in the environment louder. Assistive listening devices and alerting devices can increase the loudness of a desired sound, like a radio or television, a public speaker, or an alarm system, or may make an auditory alarm (such as a smoke signal) into a visual alarm (such as a strobe light).


No. People with all degrees and types of hearing loss -- even people with normal hearing -- can benefit from assistive listening devices. Some assistive listening devices are used with hearing aids; some are used without hearing aids.


There are many assistive listening devices available today, from sophisticated systems used in theaters and auditoriums to small personal systems.

Various kinds of assistive listening devices are listed below:

Personal Listening Systems: There are several types of personal listening systems available. All are designed to carry sound from the speaker or other sound source, directly to the listener and to minimize or eliminate environmental noises. Some of these systems, such as auditory trainers, are designed for classroom or small group use. Others, such as personal FM systems and personal amplifiers are especially helpful for one-on-one conversations in places such as automobiles, meeting rooms, and restaurants.

TV Listening Systems: These are designed for listening to TV, radio, or stereos without interference from surrounding noise or the need to use very high volume. Models are available for use with or without hearing aids. TV listening systems allow the family to set the volume of the TV, while the user adjusts only the volume of his or her own listening system.

Direct Audio Input Hearing Aids: These are hearing aids with direct audio input connections, usually using wires, which can be connected to the TV, stereo, tape, and/or radio as well as to microphones, auditory trainers, personal FM systems and other assistive devices.

Telephone Amplifying Devices: Most, but not all, standard telephone receivers are useful with hearing aids. These phones are called " hearing aid compatible." The option on the hearing aid is called the T-Coil. The T-coil is automatically activated on some hearing aids and manually activated on others. Basically, the telephone and the hearing aids T-coil communicate with each other electromagnetically, allowing the hearing aid to be used at a comfortable volume without feedback and with minimal background noise. You should be able to get hearing-aid-compatible phones from your telephone company or almost any retail store that sells telephones. Not all hearing aids have a "T" switch. Make sure your hearing aids have a T switch before purchasing a new hearing aid compatible phone! There are literally dozens of T-coil and telephone coupling systems. Speak with your audiologist to get the most appropriate system for your needs.

Cell Phones: Most hearing aids can be used with most cell phones. Importantly, digital hearing aids and digital phones may create constant noise or distortion. There may be significant problems for some hearing aids when used with particular cell phones! The best person to address this problem is your audiologist speak with your audiologist BEFORE you buy a cell phone or hearing aids!!!!

Regarding "hands free" systems, there are many to choose from and hearing impaired users usually benefit maximally by using binaural hands free systems, or, headsets with loudness controls in tandem with telephone systems.


Tinnitus is the term for the perception of sound when no external sound is present. It is often referred to as "ringing in the ears," although some people hear hissing, roaring, whistling, chirping, or clicking. Tinnitus can be intermittent or constant, with single or multiple tones. Its perceived volume can range from very soft to extremely loud.


50 million Americans experience tinnitus. Of these, about 12 million have tinnitus which is severe enough to seek medical attention. Of those, about two million patients are so seriously debilitated by their tinnitus, they cannot function normally on a day-to-day basis.


The exact cause (or causes) of tinnitus is not known in every case. There are, however, several likely factors which may cause tinnitus or make existing tinnitus worse: noise-induced hearing loss, wax build-up in the ear canal, certain medications, ear or sinus infections, age-related hearing loss, ear diseases and disorders, jaw misalignment, cardiovascular disease, certain types of tumors, thyroid disorders, head and neck trauma and many others. Of these factors, exposure to loud noises and hearing loss are the most common causes of tinnitus. I strongly recommend that an audiologist and a physician should evaluate all tinnitus patients.


There are many options for people who experience tinnitus. Some wear hearing aids to help cover up their tinnitus, some wear tinnitus maskers. Additionally, there are combined tinnitus maskers and hearing aids all in one unit! Some patients require counseling to help them develop effective management strategies to manage their tinnitus. If youve been told "learn to live with it," there are many additional options to explore. Your audiologist is an excellent resource for issues and answers related to tinnitus. Additionally, I recommend all people with tinnitus visit the American Tinnitus Association website for more information, ideas and strategies concerning tinnitus. http://www.ata.org/


Middle ear implants are surgically implanted devices. Particular middle ear implants have been approved by the FDA for specific hearing losses, such as chronic middle ear conductive hearing loss and Single Sided Deafness (SSD).

Middle ear implants are very useful hearing instruments and are quite different from traditional hearing aids.

Generally speaking, when a hearing aid is placed in/on the ear, the sound amplified by the hearing aid is transmitted to the ear via AIR CONDUCTION. Middle ear implants work by vibrating the middle ear bones to produce a BONE CONDUCTION signal, or - middle ear implants deliver a vibration, transmitted via BONE CONDUCTION to the skull, and consequently to the inner ear.

Middle ear implants are less likely to produce feedback and they do not occlude ("plug up") the ear canal. The reported benefits of middle ear implants include; elimination of the occlusion effect, elimination/reduction of feedback, reduction in distortion, improved clarity and sound quality, as well as some cosmetic advantages.

For more information on middle ear implants, please visit BAHA.


Generally speaking, cochlear implants are for patients with severe-to-profound, sensorineural hearing loss. There are approximately 500,000 patients in the USA with severe-to-profound hearing loss. Cochlear implants are only recommended after the patient has tried appropriately fitted hearing aids and has not shown sufficient benefit from hearing aids. Cochlear implants are devices that are "permanently" surgically implanted into the inner ear.

Cochlear implantation is a surgical procedure performed by otolaryngology surgeons. Cochlear implants have been FDA approved for almost two decades and the advances and improvements in the technology have been amazing. The Food and Drug Association (FDA) and the American Medical Association (AMA) recognize cochlear implants as safe and effective treatment for severe-to-profound sensorineural hearing loss. Most insurance programs pay for cochlear implantation.

Appropriately identified adults as well as profoundly deaf children (aged 12 months or older) can be implanted. Research demonstrates that the earlier a deaf child is implanted, the better the long term result will be with respect to speech and language development. Following surgery, rehabilitation is necessary, as the child must learn to associate the sound signals with normal sounds. Regarding deaf adults, research suggests that adults who receive cochlear implants are less lonely, have less social anxiety, are more independent, have increased social and interpersonal skills, and of course, they hear better with the cochlear implant! The majority of cochlear implant recipients wearing digital cochlear implants are able to use the telephone.

Cochlear implants are utilized in the patient who cannot benefit from hearing aids. The cochlear implant is a device used to bypass the nonfunctional inner ear and converts sound into electrical impulses that directly stimulate the cochlear nerve. The implant consists of an external portion comprised of a microphone, sound processor, and external coil and an internal portion that must be surgically implanted. The surgical procedure involves the placement of an internal receiver beneath the skin behind the ear, and a stimulating electrode array is inserted into the cochlea. The electrical signals are manipulated and controlled by the audiologist to maximize speech perception. The brain interprets these electrical impulses as sound. Again, not all patients are surgical candidates, and not all cochlear implant recipients receive the same benefit.

It is important to remember that the vast majority of patients who receive cochlear implants are actually "deaf" prior to implantation and they have not been successful with traditional hearing aids. Your audiologist is a very knowledgeable resource regarding cochlear implants and will be happy to discuss them with you.

Please review this information with your spouse or loved ones and please feel free to discuss all of these issues with your audiologist and/or your physician.

Federal regulation prohibits any hearing aid sale unless the buyer has first received a medical evaluation from a licensed physician. However, if you are at least 18 years old, you can sign a form (waiver) that says you are fully aware of your rights but choose not to have the medical evaluation. For people under 18 years of age, waiver of the medical evaluation is not permitted. These rules and regulations may vary state-by-state and you need to check with your state rules, regulations and laws. I do not recommend using waivers.

I believe your best health interest is served by seeing a licensed audiologist for a complete audiometric evaluation and seeing an otolaryngologist for medical and/or surgical diagnosis and treatment of all ear and hearing disorders and diseases.

The opinions throughout this article are those of the author. Other audiologists, hearing instrument dispensers and otolaryngologists may have different opinions and recommendations. Additionally, each patient and each hearing problem is unique. "Self-diagnosis" and treatment is unwise, is not recommended and may indeed lead to a worsening situation.

State and federal rules and regulations vary from location-to-location and they change over time.
