Abstract
This paper represents the results of studies designed to provide information security of radio communication channels transmitting speech messages. On the basis of empirical data on the human hearing sensitivity thresholds, some threshold signal noise ratios were determined at the input of an intelligence receiver, where an operator can hardly read messages at the lowest possible limit.Keywords:
