Abstract
A side-tone circuit comprises a microphone configured to generate a reverse link audio signal and a side-tone noise suppressor. The side tone noise suppressor is configured to receive the reverse link audio signal, suppress noise in the received reverse link audio signal, and output a noise suppressed side-tone signal. The side-tone noise circuit also includes a speaker configured to receive the noise suppressed audio signal and communicate it to a user.
