Abstract :
A digital signal processing based hearing aid has been produced which can be used as a body worn device, with transmitter and receiver in a conventional behind the ear hearing aid case. The design is based on the TMS320C31-27 DSP device. Use of this low power chip allows the aid to perform for up to 8 hours without battery replacement and facilitates field testing of different algorithms designed to enhance hearing aid performance
