A voice activity detector was implemented to estimate the slow varying noise spectrum adaptively.- These were applied to synthesized pseudo-random additive white noise and recorded helicopter noise. The performances of these methods were compared based on the gain in SNR achieved over the input SNR as well as through subjective listening tests. Show less
