[Substantiation of MPEL of acoustic exposure in accordance with its informational value].
The authors suggest that information component of acoustic impact, leading to physiologic changes, should be considered through regulation of entropy in occupational acoustic environment when being an information source. Studies of hearing and some vegetative functions before and after a noise lasting for hour proved that with the current levels (60-80 dB A) and entropy (1.25-2.85 byte/symbol) higher energy of the stimulus is balanced by its lower information load.
