Abstract :
The paper addresses the problems of impulsive noise detection for audio signals. A structure of threshold parameter detectors using modeling of signal was introduced. The algorithm of noise detection, based on discrete-time hidden Markov model (HMM) of whitened audio signal is elaborated.
