Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back System of weakening of acoustic feedback based on the analysis of periods of neighboring oscillations A.L. GALIEV, А.F. SHISHKINA This article discusses a system of reducing acoustic feedback by analyzing periods of neighboring oscillations of the sound signal. Examines one of the particular criteria of stability, established for the start of self-excitation of electroacoustic systems. The structural diagram of the developed device is given, as well as the principle of it’s work. Keywords: acoustic feedback, self-excitation of electroacoustic systems, speech intelligibility, adjustment of amplification factor.
