How hearing aids work

Perhaps you've thought about getting a hearing aid, but you're worried about how it will look or whether it will really help. It may help ease your concerns to know more about:

  • The hearing aid options available to you

  • What to look for when buying a hearing aid

  • How to get used to it

Hearing aids can't restore normal hearing. They can improve your hearing by amplifying soft sounds, helping you hear sounds that you've had trouble hearing.

Hearing aids use the same basic parts to carry sounds from the environment into your ear and make them louder. Most hearing aids are digital, and all are powered with a hearing aid battery.

Small microphones collect sounds from the environment. A computer chip with an amplifier converts the incoming sound into digital code. It analyzes and adjusts the sound based on your hearing loss, listening needs and the level of the sounds around you. The amplified signals are then converted back into sound waves and delivered to your ears through speakers.

Completely in

the canal (CIC)

A completely-in-the-canal hearing aid is molded to fit inside your ear canal. It improves mild to moderate hearing loss in adults.

A completely-in-the-canal hearing aid:

  • Is the smallest and least visible type

  • Is less likely to pick up wind noise

  • Uses very small batteries, which have shorter life and can be difficult to handle

  • Doesn't contain extra features, such as volume control or a directional microphone

  • Is susceptible to earwax clogging the speaker

In The Ear (ITE)

An in-the-ear (ITE) hearing aid is custom made in two styles — one that fills most of the bowl-shaped area of your outer ear (full shell) and one that fills only the lower part (half shell). Both are helpful for people with mild to severe hearing loss.

An in-the-ear hearing aid:

  • Includes features that don't fit on smaller style hearing aids, such as a volume control

  • May be easier to handle

  • Uses a larger battery for longer battery life

  • May pick up more wind noise than smaller devices

  • Is more visible in the ear than smaller devices

Behind The Ear

A behind-the-ear (BTE) hearing aid hooks over the top of your ear and rests behind the ear. A tube connects the hearing aid to a custom earpiece called an earmold that fits in your ear canal. This type is appropriate for people of all ages and those with almost any type of hearing loss.

  • A behind-the-ear hearing aid:

  • Traditionally has been the largest type of hearing aid, though some newer mini designs are streamlined and barely visible

  • Is capable of more amplification than are other styles

  • May pick up more wind noise than other styles

In The Canal

An in-the-canal (ITC) hearing aid is custom molded and fits partly in the ear canal. This style can improve mild to moderate hearing loss in adults.

An in-the-canal hearing aid:

  • Is less visible in the ear than larger styles

  • Includes features that won't fit on completely-in-the-canal aids, but may be difficult to adjust due to its small size

  • Is susceptible to earwax clogging the speaker


Musicians have unique needs when it comes to hearing protection. They need to protect their hearing, but they also need to be able to hear their own music clearly, as well as hear other musicians' music and voices while performing. Musician's ear plugs come in both custom and non-custom options. Ready-fit musician ear plugs can reduce sound levels by approximately 20 dB, enough to reduce harmful sound without distorting speech or music. Most musicians do not need maximum protection. What they need is mid- to low-frequency protection. This can be accomplished through ear plugs that are specifically designed for musicians. 



Anytime hearing protection is removed, even for a short period of time, the ear is exposed to damaging noise. Noise exposure is cumulative. Exposure to damaging noise levels, for short periods of time, creates a cumulative effects as if the ear was exposed for the sum of those brief periods. Removing hearing protection for communication or other reasons creates this cumulative effect. Don’t risk noise induced hearing loss. Wear custom fit earplugs for maximum hearing protection.
