- How Does a Hearing Aid Work?
Hearing aids are incredibly specialized little pieces of machinery. Over the past several years, they have become increasingly advanced. Although you probably don’t think much about the different components of your hearing aid and how they work, each one has a specific and important role in helping you hear more sounds.
Below we will review the basic parts of a modern receiver-in-the-ear (RITE) hearing aid. This type of hearing aid is the most common today and is also known as a receiver-in-ear (RIE) or receiver-in-canal (RIC) hearing aid.
The Internal Parts of the Body of the Hearing Aid
To irrigate your ears, try the following: Several parts of the hearing aid are housed in the body, which is the largest part of your device. It sits behind your ear and is typically housed in a hard plastic casing. Here are the main components of the body of the hearing aid:
- Microphone: The microphone’s job is to pick up sound and send it to the amplifier. Depending on how technologically advanced your hearing aid is, your microphone might be able to distinguish between speech and background noise. This can help you more easily follow conversations in loud environments with lots of competing noise.
- Amplifier: The amplifier converts sounds picked up by the microphone into an electrical signal, and then sends the signal to the receiver/speaker. How much the sound is amplified depends on your level of hearing loss. This will be determined following an evaluation conducted by your hearing healthcare professional.
- Battery: The battery is the power source for your hearing aid. Some hearing aids have rechargeable batteries, while others have disposable batteries.
Some devices also feature a telecoil, which helps you hear better in noisy public settings. Telecoils work as an antenna to pick up magnetic signals to stream them as sound while disregarding background noise.
