... the noise PSD. With a VAD the noise PSD is estimated during speech pauses. However, VAD based noise PSD estimation fails when the noise is non-stationary. An alternative is to estimate the noise ... increases. The QB noise PSD estimator is slightly better in following the increasing noise levels, however, compared to MS, it has more problems in tracking the noise PSD...
