Development of an Algorithm for Suppression of Concentrated Acoustic Noise in Telecommunication Systems

The article discusses a method for dealing with concentrated acoustic interference in telecommunication audio exchange systems. The study and development of algorithms for processing speech signals that increase the efficiency of information-control telecommunication systems of audio exchange under the influence of external concentrated acoustic noise of high intensity are carried out in the work. A telecommunications system for transmitting speech information is considered, an algorithm for calculating the signal-to-interference ratio is proposed, the influence of noise interference on the perception of signals received at the output of a telecommunication system is estimated. An adaptive algorithm for generating a control signal is proposed, which makes it possible to turn off channels affected by concentrated interference, the efficiency of the proposed algorithm and the dependence of possible losses of a useful signal on the choice of a rejection band are estimated.
