Objective tests and the assessment of the acoustic properties of ear-plugs

Archives of Acoustics, 2014
Ear-plug-type hearing protectors are commonly used in a noisy working environment. In a certification process of ear-plugs only sound attenuation is tested subjectively. There is no requirement of maximum variability in ear-plug insertion loss measured
