Abstract - (Show below) - (Hide below)

Describes a method for measuring sound attenuation of hearing protectors at the threshold of hearing, to yield values close to the maximum attenuation which are not normally attained under field conditions. This has been adopted because the attenuation values can then be consistently reproduced. This method provides data which are collected at low sound pressure levels but which are also representative of attenuation values at higher levels. An exception is amplitude sensitive hearing protectors for sound pressure levels above the point at which their level dependent characteristics become effective. At this level the method specified is inapplicable. AMD 7552 renumbers this standard to EN 24869 1
