The sound is received by the microphone of the hearing aid, which is then converted into a digital sign
The strength of this digital sign is increased by the amplifier
The speaker then passes the sound into the ear.
Hearing aids have a microphone that is sensitive enough to pick up on all the sounds around you. These sophisticated microphones can even differentiate between sounds. For example, they can identify which sounds are speech sounds you want to hear and which sounds are distracting background sounds you don’t want to hear. The microphone will also convert the sound waves into electrical signals and send them to the processor.
The most complex part of the hearing aid is the processor or amplifier. This is a small computer chip that can manipulate and change the electrical signals. When sounds reach the processor, they are changed to match your hearing. Certain sounds will be amplified while other sounds will be reduced. Any feedback or other interference is also reduced. If you have your tinnitus therapy program turned on, the processor also adds these features.
Once the sound has been manipulated, the sound is sent to the receiver. This part of the hearing aid will convert the digital signals back into sound waves, create audible sound and direct that sound into your ears.
