What is a hearing aid?
Accordion Toggle
Hearing aids are small electronic devices that you select with the help of your hearing professional. They are worn in or behind your ear. They are programmed for the individual needs and personal prescription, based on hearing test results, of a person with hearing loss, so they can listen, communicate and participate more fully in daily activities. Hearing aids can help people hear better in both quiet and noisy situations.

A hearing aid has three basic parts: the microphone, amplifier and receiver (speaker). The hearing aid receives sound through the microphone, which converts the sound waves to electrical signals and sends them to the amplifier. The amplifier increases the power of the signals and then sends them to the ear through the receiver.

How can hearing aids help?

Hearing aids are primarily useful in improving the hearing and speech comprehension of people who have hearing loss from damage to the small sensory cells in the inner ear, called hair cells. This type of hearing loss is called sensorineural hearing loss. The damage can occur as a result of disease, aging, or injury from noise or certain medicines.

A hearing aid magnifies sound vibrations entering the ear. Surviving hair cells detect the larger vibrations and convert them into neural signals that are passed along to the brain. The greater the damage to a person’s hair cells, the more severe the hearing loss, and the greater the hearing aid amplification needed to make up the difference. However, there are practical limits to the amount of amplification a hearing aid can provide. In addition, if the inner ear is too damaged, even large vibrations will not be converted into neural signals. In this situation, a hearing aid would be ineffective.

How can I find out if I need a hearing aid?
Accordion Toggle

During your visit, an audiometric exam will be conducted. This exam will determine if you have a hearing loss and if it’s correctable by hearing aids. If you have a hearing loss and it is determined that it cannot be corrected with hearing aids, you will be referred out to an otolaryngologist. An otolaryngologist is a physician who specializes in ear, nose and throat disorders, and will investigate the cause of the hearing loss.

Do all hearing aids work the same way?
Accordion Toggle

Hearing aids work differently depending on the electronics used. The two main types of electronics are analog and digital.

Digital Aids

Digital aids convert sound waves into numerical codes, similar to the binary code of a computer, before amplifying them. Because the code also includes information about a sound’s pitch or loudness, the aid can be specially programmed to amplify some frequencies more than others. Digital circuitry gives a hearing professional more flexibility in adjusting the aid to a user’s needs and to certain listening environments. These aids also can be programmed to focus on sounds coming from a specific direction. Digital circuitry can be used in all types of hearing aids.

Analog Aids

Analog aids convert sound waves into electrical signals, which are then amplified. Analog processing is no longer commonly used in today’s hearing aids, with the notable exception of the Lyric device.

Which hearing aid will work best for me?
Accordion Toggle

The hearing aid that will work best for you depends on the kind and severity of your hearing loss. If you have hearing loss in both ears, two hearing aids are generally recommended, because two aids provide a more natural signal to the brain. Hearing in both ears also will help you understand speech and locate where the sound is coming from.

You and your hearing professional should work together to select a hearing aid that best suits your lifestyle and needs, and that also fits your budget. Style and features can affect cost, and the most expensive hearing aid may not always be the best suited device for you.

A hearing aid will not restore your normal hearing. With practice, however, a hearing aid will increase your awareness of sounds and their sources. You will want to wear your hearing aid regularly, so select one that is convenient and easy for you to use.

What questions should I ask before buying a hearing aid?
Accordion Toggle

Before you buy a hearing aid, ask your hearing professional these important questions:

  • What instruction and services will the hearing professional provide?
  • What features would be most useful to me?
  • Will loaner aids be provided when repairs are needed?
  • What is the total cost of the hearing aid?
  • Is there a trial period to test the hearing aids?
  • What fees are nonrefundable if the aids are returned after the trial period?
  • How long is the warranty?
  • Can the warranty be extended?
Can I obtain financial assistance for a hearing aid?
Accordion Toggle

Hearing aids are generally not covered by health insurance, although most companies will have some forms of financing available. Financing is usually available, with some plans even offering 0% financing.

What research is being done on hearing aids?
Accordion Toggle

Researchers are looking at ways to apply new signal processing strategies to the design of hearing aids. Signal processing is the method used to modify normal sound waves into amplified sound that is the best possible match to the remaining hearing for a hearing aid user. NIDCD-funded researchers also are studying how hearing aids can enhance speech signals to improve understanding.

In addition, researchers are investigating the use of computer-aided technology to design and manufacture better hearing aids. Researchers also are seeking ways to improve sound transmission and to reduce noise interference, feedback and the occlusion effect. Additional studies focus on the best ways to select and fit hearing aids in children and other groups whose hearing ability is hard to test.

What is the difference between an Audiologist and a Hearing Instrument Dispenser?
Accordion Toggle

An audiologist is a licensed professional who has a master’s or doctoral degree in audiology. Audiologists are clinically, academically and professionally trained to determine which hearing losses require medical referral and/or assistive listening devices. Audiologists often focus on diagnosis and pediatric patients.

Hearing instrument specialists are also qualified, trained and licensed to evaluate hearing and fit hearing aids. Their focus is on treating sensorineural hearing loss (hearing loss related to inner ear).

How do I know if I have hearing loss?
Accordion Toggle

The most common complaint a hearing impaired person will express is, “I hear you, but I don’t understand you.”

You may have hearing loss if…

  • You hear people speaking, but have to strain to understand their words.
  • You frequently ask people to repeat what they said.
  • You don’t 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 looking at people when they speak to you makes them easier to understand.
Why should I get two hearing aids?
Accordion Toggle

If you are a hearing aid candidate in both ears, you should wear two hearing aids. You have two ears because you need two ears. If we 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.

Localization (knowing where the sound came from) is only possible with two ears. 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 downplaying undesired sounds such as background noise.

People cannot hear well using only one ear. There are studies in the research literature that show children with one normal ear and one “deaf” ear are ten times more likely to repeat a grade as 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 understanding ability more quickly than the ear wearing the hearing aid.

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 easier while using both ears. Additionally, using two hearing aids allows people to speak with you from either side of your head – not just your “good” side!

How can I adjust to my hearing aid?
Accordion Toggle

Hearing aids take time and patience to use successfully. Wearing your aids regularly will help you adjust to them.

Become familiar with your hearing aid’s features. With your Hearing Care Professional present, practice putting in and taking out the aid, cleaning it, identifying right and left aids, and replacing the batteries. Ask how to test it in listening environments where you have problems with hearing. Learn to adjust the aid’s volume and to program it for sounds that are too loud or too soft. Work with your Hearing Care Professional until you are comfortable and satisfied.

What are some of the adjustment issues people experience with hearing aids?
Accordion Toggle

You may experience some of the following problems as you adjust to wearing your new aid.

My hearing aid feels uncomfortable.

Some individuals may find a hearing aid to be slightly uncomfortable at first. Ask your Hearing Care Professional how long you should wear your hearing aid while you are adjusting to it.

My voice sounds too loud.

The plugged-up sensation that causes a hearing aid user’s voice to sound louder inside the head is called the occlusion effect, and it is very common for new hearing aid users. Check with your Hearing Care Professional to see if a correction is possible. Most individuals get used to this effect over time.

I get feedback from my hearing aid.

A whistling sound can be caused by a hearing aid that does not fit or work well or is clogged by earwax or fluid. See your Hearing Care Professional for adjustments.

I hear background noise.

A hearing aid does not completely separate the sounds you want to hear from the ones you do not want to hear. Sometimes, however, the hearing aid may need to be adjusted. Talk with your Hearing Care Professional.

I hear a buzzing sound when I use my cell phone.

Some people who wear hearing aids or have implanted hearing devices experience problems with the radio frequency interference caused by digital cell phones. Both hearing aids and cell phones are improving, however, so these problems are occurring less often. When you are being fitted for a new hearing aid, take your cell phone with you to see if it will work well with the aid.

How do I care for my hearing aids?
Accordion Toggle

Proper maintenance and care will extend the life of your hearing aid. Make it a habit to:

  • Keep hearing aids away from heat and moisture.
  • Clean hearing aids as instructed. Earwax and ear drainage can damage a hearing aid.
  • Avoid using hairspray or other hair care products while wearing hearing aids.
  • Turn off hearing aids when they are not in use.
  • Replace dead batteries immediately.
  • Keep replacement batteries and small aids away from children and pets.
Are new types of hearing aids available?
Accordion Toggle

There is new technology available for patients who have mild to moderate hearing loss and who have larger canals. These include the analog Lyric device, IIC (invisible-in-the-canal) devices and CIC (completely-in-the-canal) devices. These hearing aids fit deeply in the canal, are invisible and are often best suited for patients with concerns about visibility.
