A.1 Repeatability and reproducibility of sound
attenuation measurements on ear-muffs at a
probability level of 95% (according to ISO 5725)
A.2 Repeatability and reproducibility of sound
attenuation measurements on ear-plugs at a
probability level of 95% (according to ISO 5725)
Method for measuring sound attenuation at the threshold of hearing, giving consistently reproducible values which are close to the maximum attainable but are unlikely to be achieved in use.
