Abstract :
The method of formation of the combined masking signals for the systems of protection of speech information from the leakage on acoustic channels is validated. The combined masking signals include "white" noise in the range of frequencies from 125 to 6500 Hz and signals of outburst character (speech-like signals). Ratios between the specified types of signals are picked out from the language of the speech signal demanding protection.
