The technique uses the auditory masking threshold to extract information for the audible noise components. Those components are then removed using adaptive nonlinear spectral modification. The main advantage of such an approach is that the speech signal is not affected by processing. In addition, very little information on the features of the noise is required. The proposed method was found to perform well for SNRs better than 10 dB, while for lower SNRs its performance was superior to that of spectral subtraction.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
