FIELD: radio engineering, communication.
SUBSTANCE: invention relates to methods for receiving signals when they leak from a protected room through various technical channels, and can be advantageously used for remote interception of confidential acoustic voice information circulating in the protected room. A fibre-optic link passing in the room adjacent relative to the protected room is used, running along their common wall. In order to convert an acoustic voice signal, its transformation into a vibration signal is used, which then spreads through the wall and, thanks to the mechanical connection between the wall and the devices for fixing the fibre-optic link, running in the adjacent room along the common wall, affects on the fastening devices, and through them - on the fibre-optic link.
EFFECT: providing interception in the absence of a fibre-optic link in a protected room.
