Understanding How Your Hearing Aid Works

The Structure Of A Hearing Aid And How It Works

A hearing loss can have a profound impact on your life, your career, and your relationships. If you choose the correct one, a hearing aid can make a significant difference in your ability to communicate while enhancing your enjoyment of life. Knowing what goes into the design of hearing aids will help you choose the most appropriate device for your hearing needs. Regardless of the style of hearing aid you have, all hearing aids share three essential components:

  • The hearing aid microphone picks up sounds and sends them to the amplifier. New technology distinguishes between speech and background noise, making it easier to understand a conversation.
  • Converting sounds from the microphone into an electrical signal and then sending the message to the receiver is the function of the amplifier. Amplification power is dependent upon the severity of the user’s hearing loss.
  • Power source. Batteries power the hearing device. Batteries may be either rechargeable or disposable, depending on the model.

These three components are in all hearing aids. Depending on the design and the severity of your hearing loss, a few other parts might be residing inside your hearing aid.

Buttons And Switches

Hearing aids that are of the receiver-in-the-ear (RITE) type come equipped with a button or a switch. A hearing healthcare professional programs the button or switch to perform different functions such as alternating between settings or increasing and decreasing volume. Make a point of knowing the purpose of your switch.

Wire

A hearing aid wire is typically thin and coated in plastic. The wire extends from the body of the hearing aid to the speaker, which resides in the ear. The transmission of power and signals takes place in the wire. Hearing aid wires feature conductor materials, shielding, and jacketing manufactured for custom hearing solutions.

Receiver/Speaker

Delivering the sound to the ear is the responsibility of the receiver, which is also known as the speaker. When the speaker receives an electrical signal from the amplifier, it converts it to sound. The speaker is inside the ear dome or earmold, depending on the severity of hearing loss and lifestyle.

Domes

A dome is a small piece of silicone that attaches to hearing aid tubing and fits deep in the ear canal. Domes come in an array of shapes and sizes to accommodate the unique anatomy of a person’s ear canal. A hearing healthcare professional can help you pick the appropriate size for a proper fit.

Earmold

Earmolds are plastic or acrylic and fit inside your ear canal to form an acoustic seal for the electronic sound coming in. The fit and the shape of your earmold will depend on the model of hearing aid you are utilizing and the severity of your hearing loss. Because they provide the highest amount of amplification, earmolds are for those with severe to profound hearing loss.
Hearing loss is a severe health issue, so do not ignore it. If you suspect that you may have a hearing loss, schedule a hearing screening with a hearing healthcare professional. Swift acting will significantly enhance the quality of your life.
