This paper deals with musical noise resulting from subtractive type algorithms and especiallyWiener filtering. We compare several methods that introduce perceptually motivated modifications of standard Wiener filtering and we propound a new speech enhancement technique. It aims to improve the quality of the enhanced speech signal provided by standard Wiener filtering by controlling the latter via a second filter regarded as a psychoacoustically motivated weighting factor. According to objective measures, the described process results in significant reduction of musical noise.
