DIGITAL CIRCUITRY Close this Window to Return to our Info Page
In the near future most all hearing aids will be a digital technology. Digital technology allows the hearing aid to make decisions based on the incoming signal. Digital circuitry is an active circuit that is making multiple assessments of the listener's environment and determining how various sounds should be amplified based on the input to the hearing aid. Digital hearing aids have a wide range of flexibility in the programming capability, allowing extremely specific adjustment for each individual's hearing loss. A digital signal is a clearer signal that is free from distortion. Volume controls are not necessary in digital products due to the fact that the automatic volume ability is extremely effective. Digital hearing aids allow for different programs to be installed into the instrument as well as the utilization of dual and directional microphones and automatic feedback cancellation.
The first digital hearing aid was introduced by Oticon in 1996
