Amplifier The amplifier is the part of a hearing aid that receives incoming sound and amplifies it before delivering it to the user’s ear. The amplification is based on either digital or analog technology.

The amplifier contains most of the hearing aid’s electronic components and circuits.

The microphone delivers the incoming signal to the amplifier, where it is pro-cessed and amplified according to the user’s amplification needs and the hearing aid settings. The amplified and improved signal is then sent to the eardrum via the hearing aid receiver.

Filters and AGC (Automatic Gain Control) are used to fine tune the amplified sound to provide the best possible quality.
