How a hearing aid works

A hearing aid can help people hear better again. There are various models, which usually differ in design, construction or even the range of functions. However, the functionality usually does not differ.

1. A hearing aid consists of a microphone, a button for settings, a battery compartment and a matching earpiece. In addition, a hearing angle and a hearing tube also belong to it. Inside are also an amplifier and a speaker.
2. If sound hits the hearing aid, it is picked up by the microphone. Subsequently, the sound is converted into electrical pulses.
3. With the help of a microchip, the pulses are processed depending on the required signal. This may differ depending on the type of hearing loss and is programmed accordingly.
4. Alien noises that could limit the audio quality are filtered out.
5. Depending on whether it is an in-the-ear or a behind-the-ear system, the transmission is conducted directly through the ear canal or first through a sound tube.
6. With the help of the battery, the device is supplied with power. Diese muss je nach Gerät mehr oder weniger häufig ausgetauscht werden.
