Modern hearing aids are complex and custom-created digital electroacoustic devices that can be computer programmed to amplify sounds at certain frequencies. When the technology used in digital hearing aids has considerably enhanced in the last fifty years, all hearing instruments retain the exact same standard functions and pieces.
Fundamental Hearing Help Functions:
In all hearing aids sound waves enter via the microphone, which converts acoustic signals into electrical signals or pulses. The amplifier then increases the strength of the electrical signal and cleans up any noise it detects. This electrical signal is then converted back into an acoustic signal so that the user can hear it. The receiver then channels the sound into the ear canal. A battery supplies the required energy for these conversion processes. Many digital hearing aids also have numerous options and controls like toggle switch, volume manage wheels, push buttons, remote controls, and directional microphones that allow the wearer to hear much better in unique listening environments.
