摘要：

In this correspondence, we investigate whether musical noise, which often exists in speech enhanced using spectral subtraction, can be suppressed. Via exploiting some specific characteristics of human speech, we propose a method that can effectively suppress musical noise without noticeable effect on speech intelligibility. Performance assessments confirm that our method is effective.
