Speech information security device «Priboi-r»

Speech protection device «Priboi-R» is used for speech information protection from leakage through acoustic and vibration channels from rooms, outside the protected area. The device is an automatically controlled source of acoustic noise excitations and vibrations which mask speech in the building and in other possible acoustic channels of information leakage (depending on the level of the speech signal in the protected area/room). ADVANTAGES: the device forms masking signals of «white noise», «speech-like signals», «white noise» + «speech-like signals», which provide closure of possible information leakage channels; «speech-like signals» are formed by microprocessor according to the random law and correspond to all of the formal qualities of speech (presence of formant signal characteristics, frequency of the main tone, equal to the frequency of the main tone of the masking speech, pauses between words) and can be adapted for a certain person.
