Abstract :
Noise suppression from speech signal is one of the fundamental problems in audio processing applications. In this paper, a frequency domain based noise suppression algorithm is realized on FPGA. The algorithm is suitable for small, single microphone systems such as the hearing aids where the microphone and the speaker are very close to each other. Estimation of noise is performed adaptively so that the system becomes robust to changes in the environment.
