[Impulse acoustic and mechanical processes and their medico-biological evaluation]

Impulse mechanical and acoustic processes whose action on the body of man may result in unfavourable consequences are ever widely practiced today in industry and in the environment. Impulse processes are characterized by certain physical peculiarities which determine the specificity of their biological effect. In turn, this gives rise to the problems of their hygienic estimation and standardization. At the same time out of the diversity of physical parameters which characterize impulse noise and vibration, one should choose, for hygienic estimation and standardization, only those of them that are responsible for the biological effect to the greatest degree. Different authors suggest different approaches to the hygienic standardization of those processes, which depends on what parameters are recognized by them as more adequate to their biological effect.
