How do the hearing aids work?/edit by adsound

Hearing aids are tiny in size but mighty in sound – but where does all that sound come from? Beyond their shiny shells, hearing aids have tiny computers working tirelessly to give you the best sound possible. Making up this electronic hearing wonder are 5 key components. Here’s how they work.

Main Parts of a Hearing Aid

It all starts with a microphone. The hearing aid microphone picks up incoming sound and sends it to an amplifier, which processes the sound by turning it from an analogue signal into a digital signal. This is then sent to the receiver which the delivers the sound to your ear in a way that is most true-to-life.

More on these 5 hearing aid parts:

  • MICROPHONE: The microphone helps the hearing aid to pick up sounds from outside the ear. There are different types of microphones, both omnidirectional (sensitive to sound from all directions) and directional (sensitive to sound from specific directions).

  • AMPLIFIER: The amplifier processes and strengthens the sound signal from the microphone and customizes it according to your individual needs and your hearing loss. It makes the sounds you hear recognizable without being distorted.  The amplifier contains most of the hearing aid’s electronic components and circuits in a microchip.

  • MICROCHIP: The chip is the nervous system of the hearing aid. Despite its micro size, the chip is incredibly powerful and can handle everything from signal processing to wireless communications. The     chip means that hearing aids can be smaller and use less battery power.

  • RECEIVER: The receiver or speaker converts the electrical signal into sound and sends it to your ear. How much sound comes out depends on its size. A severe hearing loss will often require a slightly larger hearing aid. Receivers also come with wax guards that help to keep moisture and earwax from entering the hearing aid.

  • BATTERY: The engines of the hearing aid, batteries keep the whole thing running. How much power a hearing aid uses varies widely depending on its size, the number of features and the ways in which it is used.
