title: [Medical and biologic evaluation of individual noise-protection means efficiency].
abstract: In laboratory and nature, the authors studied protective properties of experimental models of noise-protection earphones with high acoustic efficiency in broadened frequency range. The article covers expedience of studies at workplaces, including medical and biologic methods that evaluate noise-protection in audible and infra-sound ranges.
