Abstract: The purpose of this work is to investigate informational reliability of the system ,,man-machine-environment" and find out the difficulties of audible information spread in nosy environment. The methodical summations are used for estimation of acoustical pollution by traffic and the analysis of audible signals. Research analysis showed that "roar" and "rumble" type sounds are more important to the noise environment generated by traffic flow and ,,neutra" type sounds are more important to the ecological living zones. This acoustical environment is suitable to audible information spread due to the satisfied conditions. The significant account for audible information propagation has its amplitude frequency characteristic but human being can't dissociate the audible signals with poor speech interference level (SIL) or less than 5 dBA. Also determined that informational signals are informative when their level is at least 5 dBA higher in one of four octave bands and when hearing protector suppression is less than 20 dBA
