Hearing Aids: Reasonable Expectations for the Consumer

Rose L. Allen, Ph.D., CCC-SLP/A, Assistant Professor of Audiology, East Carolina University, Dept. of Communication Sciences & Disorders

INTRODUCTION:

Since you are considering the purchase of hearing aids, it’s important for you to establish reasonable expectations from these highly sophisticated, miniature devices. Acquiring hearing aids is not merely a simple act of going to a store and purchasing a product.

Rather, it is a complex process – one that evolves over time and begins with the hearing-impaired individual accepting the realization that hearing impairment has detrimental effects on interpersonal relationships and safety. The hearing impaired person’s motivation to hear well is the single most important factor in determining the success of the hearing aid fitting. It is important to realize that you will not experience the exact same benefits from your hearing aids as your neighbor does. This individuality is a critical component, and I want to emphasize that your expectations should be based on you, your type and degree of hearing loss, your past experiences, and the improvements you personally receive from amplification.

The title of this article implies there are reasonable expectations for the consumer. Therefore, there must also be unreasonable expectations. For the most part, there is only one totally unreasonable expectation: anticipating normal or perfect hearing.

It is my hope that this point-by-point tutorial will help guide you in establishing realistic and reasonable expectations from hearing aids, from the professionals you interact with, through the process of acquiring hearing aids, using them effectively, maintaining them, and living the fullest life possible.

  1. Expect others to notice your hearing loss before you do! A common complaint of hearing-impaired individuals is that other people mumble – and if they would just speak up, it would be easier to hear them! This is placing the blame externally, rather than accepting the reality that your ears are not as good as they used to be. Realize that it is your hearing. Take that step to have your hearing tested before you blast your loving spouse out of the den with the blaring sound of the TV set. Seek the advice of your local hearing instrument specialist (HIS) or audiologist.
  2. Expect your HIS to be knowledgeable, courteous, and accommodating. Your HIS will take a thorough case history. They are searching for information about your hearing loss, its probable cause, and whether your offspring may be affected. It is important to establish the presence of any medical condition associated with your hearing loss, as this will trigger a medical referral. Comprehensive hearing and hearing aid evaluations will be conducted. These evaluations will provide information about the degree and nature of your hearing loss, as well as your ability to process and discriminate the fine sounds of speech. Comfortable listening levels will be defined, as well as a determination about how well you tolerate loud, intense speech and other sounds. These findings are very important as they allow the professional to pre-set some of the characteristics of the hearing aid’s circuitry. You will have time to talk with the HIS about the differing styles of hearing aids (in-the-ear, in-the-canal, completely-in-the-canal, behind-the-ear), the advantages and disadvantages of each style, and maintenance issues and costs involved. Approximately 80% of all hearing aids sold fit in the ear. After you and your hearing professional determine the best style of hearing aid for your needs, an ear impression will be obtained. The ear impression is a plastic cast of your ear which reveals the exact shape of your ear, so the laboratory can place circuitry in a hearing aid shell that will fit your ear(s) only.
  3. Expect differing opinions. If you choose to seek the advice of two or more specialists, you may get differing opinions about the “best” hearing aid for you. Everyone in the hearing aid industry acknowledges the fact that there is not a single “best” hearing aid. Rather, there are many excellent hearing aid brands available, and there are many different types of circuitry that may benefit you. Your HIS uses the case history information and the evaluation results to make the best recommendation for you and your lifestyle. You can expect a recommendation to purchase two hearing aids if both of your ears are hearing impaired and are “aidable.”

    There are many benefits to binaural (two ear) hearing, including being better able to understand speech in noise and being better able to localize sound. Your HIS will explain the advantages of a binaural fitting versus a monaural (one ear) fitting in more detail. Nonetheless, it is very important to understand that if you have two ears with hearing loss and you only wear a hearing aid on one ear, you will still have significant hearing problems, even under the best of circumstances. A reasonably good analogy is to consider wearing a single eye glass for a two-eye vision problem, such as being near-sighted or far-sighted. It simply will not work well for very long!

  4. Expect to be offered a 30-day trial period. Although not always required by law, many audiologists/HISs offer a trial or rental period of 30 days for you to adapt to amplification. You may be asked to pay a non-returnable fee during this time. Ask about this trial period, and if not offered, seek a second opinion. Use this 30-day period to test the hearing aids in the environments that are typical of your lifestyle – not only at home, but also at your friends and relatives’ homes, your favorite restaurant, shopping center, grocery store, or place of worship.
  5. Expect a referral to a physician to rule out any medical condition that may contribute to your hearing loss. All hearing aids are medical devices and, as such, are governed by regulations of the Food and Drug Administration (FDA). The FDA requires that all hearing aid users be examined by a physician, preferably one who specializes in diseases of the ear. If you are over the age of 18 years, you may be given the opportunity to sign a medical evaluation waiver that will allow the HIS to proceed with your hearing aid fitting. It is in your best interest to be evaluated by a physician prior to the hearing aid fitting, but particularly so if you have a history of ear problems or hearing loss of unknown origin.
  6. Expect the hearing aids to cost more than you think they should. There are three categories of hearing aid technology: analog, digitally programmable, and digital. Analog technology has been around for many years. Aids utilizing this technology are also called “conventional” hearing aids and they are the least expensive. According to the most recent dispenser survey published in the Hearing Review in June of 2001, the average price of a hearing aid with analog technology will cost approximately $900 to $1500 per aid, depending on the size of the aid;  the smaller the aid, the larger the price. Analog hearing aids are not as common as they once were.

    Digital hearing aids use digital signal processing – the newest form of technology on the market. Digital hearing aids are indeed complete computers, similar to the personal computer on your desktop, but they are the size of a pencil eraser! These aids can cost approximately $2500 per aid. Digitally programmable hearing aids will probably cost somewhere between the conventional price and the digital price. You may benefit from any of the three types of technology. Speak with your HIS about the types of circuitry and which would be best for you. Many of the manufacturers have switched the focus of their product lines to completely digital offerings, as digital products are more efficient and have broader application. Consequently, as the demand and sales have increased, the price has gone down.

  7. Expect an initial orientation session with your HIS in which you will learn how to handle and care for your new aids. You should invite your spouse or significant other to attend this first critical session in getting oriented to your new aids. During this session, you will be taught how to operate the hearing aids, how to clean them and how to change the batteries. You will receive written information about your aids.

    It may be difficult for you to remember all the things the HIS tells you during the first session, so don’t leave the office without your instructional brochure! It will be very valuable to you, particularly during the first weeks of owning your new hearing aids.

  8. Expect a period of adjustment. It may take several days to many weeks to get used to the daily care and maintenance of the hearing aids. You’ll need time to learn how to insert and remove the hearing aids from your ears and learn to use any controls or remotes for the aids.  There is a lot to learn, and people learn at different speeds. I recommend that you go slowly, learn one thing at a time, practice, and stay in contact with your hearing healthcare professional. Many times, a spouse or significant other is very useful in helping you adjust to the new responsibilities of ownership of hearing aids. The largest adjustment you will go through is, of course, listening with your new hearing aids. You will hear sounds that you have not heard for a long time. Some of these will be good sounds, like the songs of the birds or high-pitched voices of children. Other sounds may be obnoxious, but they are sounds we need to hear for our safety and/or general knowledge of what is happening around us. These are sounds like the refrigerator or air conditioning units humming and buzzing, the sound of our footsteps, or a knock in the sound of the car engine. Research in this area has shown that this adaptation or adjustment period may last a few months. It takes time for the brain to re-learn all these sounds. Be patient!
  9. Expect your own voice to sound different. For many reasons, your voice will sound strange to you at first – like being in a barrel. This is a normal early perception, and it is often called the “occlusion effect.” If you don’t adjust to this after a few days, discuss this with your HIS. Many times, this feeling can be alleviated through changing a few physical or programmed parameters in the hearing aids. Your HIS deals with this issue regularly, and they will be able to solve this with you over a short period of time.
  10. Expect a good, comfortable fit. Initially, it will take a while to get used to having the hearing aids in your ears. You may experience a little soreness or irritation at first, but after a few days or a week, you should be able to wear the aids for several hours per day without any pain or discomfort. I always find it reassuring when patients tell me they often forget that they are wearing their aids. If your aids are not comfortable, you will not get the maximum benefit from them, and you should not wear them. Report all discomfort or irritations to your hearing healthcare professional, and do not wear the hearing aids until he/she advises you as to how to best address the problem.
  11. Expect multiple follow-up appointments. The greatest advantage of digital hearing aid technology is the flexibility in programming the sound quality, as well as many other electro-acoustic characteristics of your hearing aids. These hearing aids are highly sophisticated instruments with many features. The computer software that is used to program your hearing aids allows the HIS to make a multitude of adjustments while the aids are in your ears. You can actually hear many of the changes as the HIS is adjusting different features or characteristics.
  12. Expect to be able to hear well, but not perfectly, in quiet one-to-one situations and most small group settings. Your hearing aids will amplify sound so speech will become comfortably loud. You should be able to hear most of what is said without having to watch a person’s lips all the time. However, even people with normal hearing watch the person speaking in order to gain more information! Even when wearing the hearing aids, you should combine your vision and your hearing to maximize your benefits from the hearing aids. When sound is comfortably loud, it will be easier for you to listen, and the stress of straining to hear rapidly diminishes. Therefore, listening in social situations becomes pleasurable again. If everyday sounds are uncomfortably loud, report this to your HIS immediately.
  13. Expect an optimal “distance for hearing.” This distance depends on your hearing loss and the programming settings in your hearing aids. Once you increase the distance from the source you want to listen to, it will get increasingly difficult to hear – just like without the hearing aids.
  14. Expect to have difficulty hearing in noisy situations. You may say that you can hear fine in quiet and that the noisy situations are the ones in which you need the most help. This is a common statement made by individuals who have hearing loss. If your hearing loss progresses, your ability to hear in quiet settings is also affected. Background noise is a nuisance for everyone, even normal-hearing individuals. As sophisticated as today’s technology is, hearing aids still cannot completely eliminate background noise for you. If you are in a lot of noisy environments, it is important to discuss this with your audiologist/HIS when discussing your case history and setting your goals for improvement.
  15. Expect your hearing aids to squeal (also called “whistle” or “feedback”) under some circumstances. If a hearing aid is somewhat functioning and has a good battery in it, this squealing acoustic feedback will occur when the hearing aid is cupped in the hand. Most users find that this helps determine the status of the battery and it is a good sign! However, you should be able to wear your hearing aids at a comfortable loudness level and not experience this squeal. If you do not have a volume control on your aids, they will likely squeal when you place them in your ears, until you get them placed comfortably. Sometimes, your aids will squeal if you press the phone too tightly to your ear or when you hug another person. Report these events to your audiologist/HIS and determine what is normal, what is abnormal, and what can be done to reduce unnecessary acoustic feedback.
  16. Expect repairs. You should realize that hearing aids are incredibly sophisticated devices that are being inserted in the ear canal where moisture and ear wax is waiting to attack any foreign object! Microscopic joints that connect the tiny wires of the microphone and receiver to the computer chip in the hearing aid can be jarred loose over time. All repairs cannot be avoided, but the majority of repairs can be avoided with regular and careful maintenance! Being careful and maintaining a good preventive maintenance schedule can significantly reduce the number of repairs on hearing aids. Your aids will probably come with a standard warranty, and after that, you can purchase hearing aid insurance from a number of companies. Talk to your HIS about additional warranty options when you purchase the aids.
  17. Expect to buy batteries. Hearing aid batteries will probably last a week or two in the hearing aid. Hearing aid battery life varies based on the hearing aid circuit and the battery and also environmental conditions (temperature, humidity, et cetera). Some people ask why hearing aid batteries don’t last as long as watch batteries. The answer is the hearing aid battery accomplishes a great deal more work and requires much more electrical energy than does a watch battery. The information you receive during the hearing aid orientation session will define a reasonable length of time for your batteries. When your hearing aids are new, you might want to keep a calendar indicating the days you change batteries. Report any significant changes in battery usage to your audiologist/HIS. Many professional offices offer battery promotions or special programs for their patients. Ask your hearing healthcare professional about this.

    There are two “nevers” with batteries. NEVER keep batteries with your medicines, as you might accidentally ingest one. NEVER allow young children to handle batteries, as they might ingest them. All hearing aid batteries are toxic if swallowed. Keep them in a safe place and be sure to recycle your batteries properly.

  18. Expect to purchase new hearing aids every five years. This may come as a surprise, particularly if you just purchased a set of digital hearing aids! However, hearing aid technology changes rapidly, just like computers, and new technology may benefit you greatly. Some people may keep the same pair of hearing aids for 10 to 12 years, particularly if their hearing loss remains stable over time and if they do a great job with maintenance, but the average life expectancy is about five years.
  19. Most importantly, expect to enjoy the sounds of life again! Your hearing aids are a key ingredient to staying active and improving the quality of your life. You will once again enjoy social events, leisure activities, and conversations with your family, friends, and co-workers. Your hearing aids will also help you hear sounds to keep you safe and well.
