FULLY DIGITAL HEARING INSTRUMENTS
Your digital hearing instrument features a microphone, analog-to-digital
converter, digital signal processor, receiver, and other specialized
components to process sound.
The microphone picks up sound waves and converts them to an electrical
signal. The analog-to-digital converter encodes the electrical signal into a
digital signal, or a series of numbers. The receiver then converts the digital
signal back into sound waves. Advanced computer software allows your
hearing health professional to configure programmable digital circuits to
meet your specific listening requirements. Non- programmable hearing
instruments can be adjusted with potentiometers.
