An approach to the detection and localization of hidden inhomogeneities in the enclosing structures of the protected premises is proposed, based on the transition from the applied standard set of test signals of the appropriate level at geometric mean frequencies of octave bands to sweeping in the audio frequency range with further visualization of the recorded response. The implementation of this approach will improve the quality of assessing the security of the premises from the leakage of confidential speech information through acoustic and vibroacoustic channels.
