Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Method of suppression of acoustic feedback on the basis of the digital filter of preliminary calculation of a signal of correction O.V. NEPOMNYASCHY, V.B. DRYZHAK, K.V. KONDRATYEV, N.V. MATJUHA, V.N.SERGEEVICH The method allowing to lift sound pressure level in a sounded location without signal distortion and without origin of excitation owing to acoustic feedback is offered. Methods of determination of an impulse surge characteristic are considered. Efficiency of the offered method is reached at the expense of application of the high speed processor of handling of a signal. The analysis of results of the led experiments on the operative equipment has allowed to draw an output of possibility of the decision of the task of suppression of acoustic noises, in the light of an offered method of the preliminary calculation of a signal of correction based on the numeral filter. Key words: Digital signal processing, the suppression of acoustic feedback, a digital signal processor, algorithm. E-mail: kondratyev-37@yandex.ru; OlegN_68@mail.ru. Pp 29-31
