AS/NZ S1270:2002

AS/NZ S1270:2002 is the Australian test standard for hearing protective devices.  The AUS standard describes a test that is similar to ANSI S12.6-2008 Method B, requiring the use of inexperienced test subjects.  The goal of testing inexperienced subjects is to more accurately estimate the field attenuation provided by HPDs on end-users, as opposed to the attenuation provided to skilled and motivated laboratory subjects.  20 subjects are required for insert-type hearing protectors and 16 subjects are required for muff-type hearing protectors.
