Abstract:
Subjective listening tests lead lo the ntost reliable results in evaluating the speech quality; hov,ever, they are very costly and time consuming-
Thus an objective measure which can predict the perceived subjective quality speech would be very helpful In this paper a new method for detecting the wide-band musical noise in the acoustic signal is proposed. Musical noise is one of the major distortiorts introduced into the background noise when processed by a noise reduction system. In this paper also an objective measure is proposed which can determine the
amount of the musicalness of the residual noise. The performance of the proposed measure was verified using subjectite listening tests. istening tests shov the high correlation of lhe proposed measure u'ilh lhe perceived subjective quality ofthe background noise
