[Importance of the phonetic structure of words for their intelligibility under noisy conditions]

It was exeperimentally established that the understanding of the one- and two-syllable words depends on their phonetic structure (the presence of definite combinations of letters) as well as on the place of the accent. The force of the pronouncing of the separate words was also established not to essentially affect their understanding. The work is aimed at the working out an operator's word stock so that the words easily vulnerable by noise to be substituted for their synonyms or avoided.
