Захист акустичної інформації методом активного придушення

Abstract

Application of the method of active protection of speech information that leads to a decrease in signal / noise ratio at the border areas controlled by suppressing signal that contains confidential information. The proposed block diagram of a system that implements the principle of suppressing speech signals at the input acoustic information leakage outside the controlled zone. The prevailing system requirements suppressing speech signal to provide the same signal / noise ratio in each local volume surface that limits crossing the channel leakage of acoustic information.
