Measurements of acoustics properties for level-dependent ear-muffs
The aim of this paper is to present methods of acoustic measurements of level-dependent ear-muffs with an electronic sound restoration system switched off and on, according to EN 352-4. Measurements of sound attenuation and H, M, L criterion levels were carried out for a model of a...
