Hearing Aid Parts: Your Go-To 2024 FAQ Guide

  1. What are the parts of a hearing aid?

A hearing aid consists of a microphone (captures sound), amplifier (boosts sound), speaker/receiver (delivers amplified sound to the ear), and battery (powers the device). Modern aids may also include digital processors, control buttons, and wireless connectivity.

  1. What is the rubber piece on a hearing aid called?

The rubber piece on a hearing aid is called an ear tip or dome, which provides comfort and helps to direct the sound into the ear canal.


  1. What part of a hearing aid is the receiver?

The receiver, also known as the speaker, is the part of a hearing aid that delivers amplified sound into the ear canal.


  1. What are the parts of the hearing aid ear mold?

A hearing aid ear mold typically includes the shell (custom-fit to the user's ear), a sound bore (channels sound into the ear), and a tubing connector (attaches to the hearing aid).


  1. What are the six main stages of hearing aid fitting?

The six main stages of hearing aid fitting are: 1) Hearing evaluation, 2) Selection of the appropriate hearing aid, 3) Ear mold impression taking (if needed), 4) Hearing aid programming and fine-tuning, 5) Fitting and orientation, and 6) Follow-up and ongoing adjustments.


  1. What is the little wire on a hearing aid?

The little wire on a hearing aid is often the receiver wire, which connects the behind-the-ear component to the receiver or speaker situated in the ear canal.


  1. What is the most important part of a hearing aid?

The most crucial part of a hearing aid is arguably the amplifier, as it increases the sound levels to aid hearing. However, all components are essential for optimal functioning.


  1. What are the buttons on top of the hearing aid for?

The buttons on top of a hearing aid are for volume control, program settings, and power. They allow the user to adjust the sound to their preference and manage different listening environments.


  1. What are the two holes in the hearing aid?

The two holes in a hearing aid are typically the microphone port, for picking up sound, and the vent, to allow airflow and reduce the plugged-up sensation.


  1. How often should you change hearing aid domes?

Hearing aid domes should typically be changed every 2-3 months or sooner if they become stiff, discolored, or damaged.


  1. What is a hearing aid attached to the back of the head?

A hearing aid attached to the back of the head is likely a bone-anchored hearing aid (BAHA). BAHAs are designed for people with conductive hearing loss, single-sided deafness, or mixed hearing loss. They use a surgically implanted abutment to transmit sound vibrations directly to the cochlea through bone conduction, bypassing the outer and middle ear.


  1. How often should hearing aid molds be replaced?  

Hearing aid molds should typically be replaced every 1-2 years or when they no longer fit well, become hard, discolored, or damaged.


  1. How long do hearing aid ear molds last?

Hearing aid ear molds usually last about 1 to 2 years before they may need to be replaced due to wear, fit changes, or degradation.


  1. What does red mean on a hearing aid?

Red on a hearing aid typically indicates the right ear. Hearing aids often use color coding to help users distinguish between the right and left devices; red for right and blue for left is a common standard.


  1. What is the round dome on a hearing aid?

The round dome on a hearing aid is a soft, silicone tip that fits on the end of the earpiece (receiver or speaker) that goes into your ear canal. It helps to comfortably position and hold the hearing aid in place while also aiding in the delivery of sound. Domes come in various sizes and types, such as open, closed, or power, to accommodate different levels of hearing loss and ear canal shapes.


  1. Which hearing aid is better behind the ear or in the ear?

The choice between behind-the-ear (BTE) and in-the-ear (ITE) hearing aids depends on individual needs. BTE aids are versatile for all hearing loss levels and easier to handle, while ITE aids are less visible and suitable for mild to severe hearing loss.


  1. Is it OK to wear just one hearing aid?

Yes, it's OK to wear just one hearing aid if you have unilateral hearing loss or if one ear has significantly better natural hearing. However, for those with hearing loss in both ears, wearing two aids is generally recommended for better sound localization and understanding.


  1. What is the average lifespan of a hearing aid?

The average lifespan of a hearing aid is typically around 5 to 7 years. Proper maintenance can sometimes extend this, but technological advancements might also encourage users to upgrade sooner.


  1. How many hours a day can you wear a hearing aid?

Most people can wear hearing aids for 12 to 16 hours a day. It's recommended to wear them during all waking hours to ensure optimal hearing and communication.


  1. Can hearing aid domes be cleaned?

Yes, hearing aid domes can be cleaned. Wipe them gently with a dry cloth or tissue, and for some types, mild soap and water can be used, but ensure they are completely dry before reusing. Always follow the manufacturer's cleaning instructions.


  1. How do you get moisture out of a hearing aid tube?

To remove moisture from a hearing aid tube, detach the tube from the aid, use a blower tool designed for hearing aids to push air through, and let it air-dry completely before reattaching. Avoid using heat or sharp objects to clear the tube.


  1. Can you soak hearing aid tubes?

Yes, you can soak hearing aid tubes in warm soapy water if they are detachable and made of a material that is not affected by water. After soaking, rinse and ensure they are completely dry before reattaching.


  1. What is the best way to clean hearing aid molds?
  • Remove the mold from the hearing aid.
  • Wipe the surface with a soft, dry cloth or tissue to remove visible earwax and debris.
  • Use a mild soap and warm water for a deeper clean, if they are not electronic and as long as your audiologist says it's okay.
  • Brush out any remaining wax from the tubing and vent holes with a small brush or wax pick.
  • Rinse thoroughly with clean water if soap is used.
  • Dry completely before reattaching to the hearing aid. You can use a forced air blower (specifically designed for hearing aids) or let it air-dry.
  • Never use alcohol, solvents, or chemicals, and always check with your audiologist for mold-specific cleaning recommendations.


  1. What are the 4 most common hearing problems?
  • Conductive Hearing Loss: Issues with the outer or middle ear blocking sound.
  • Sensorineural Hearing Loss: Damage to the inner ear or auditory nerve.
  • Mixed Hearing Loss: A combination of conductive and sensorineural loss.
  • Tinnitus: A persistent ringing or noise in the ears without an external source.


  1. What is the most common hearing problem?

The most common hearing problem is sensorineural hearing loss, typically resulting from damage to the inner ear or auditory nerve.
