Abstract :
A signal processing technique using active noise control (ANC) is developed for digital hearing devices. It is implemented in a self-containing modular form and can be easily incorporated into other applications. An experimental system achieved a 10 dB-25 dB noise reduction in the frequency range 80 Hz-4000 Hz
