Abstract
With the help of physical and technical modeling system COMSOL Multiphysics 3.5a the formation of acoustic and vibroacoustic voice information leakage channels through the closed glass window in the room was studied. The influence of an
enclosed window on the acoustic field indoor and outdoor space beyond was found out. The probability of interception acoustic information through the closed window was evaluated. The formation of vibroacoustic information leakage channel was shown. The values of deformations and vibration acceleration were calculated and they had shown the high probability of formation vibroacoustic information leakage channel and interception information with appropriate technical means.
