Performance Criteria for Systems that Estimate the Attenuation of Passive Hearing Protectors for Individual Users
Also Known As:
Full Description
This standard pertains to systems intended to estimate the attenuation of hearing protection devices (HPDs)
obtained by individual wearers in actual practice. Such systems are designated field attenuation estimation
systems (FAESs). This standard provides a classification of FAESs and specifies performance criteria. It
also details the evaluation methodology and statistical calculations to be performed on such systems in
order to state the uncertainty associated with the individual attenuation estimates that they provide, and
specifies a method for computing a personal attenuation rating (PAR). FAES-derived data do not replace
the attenuation values from ANSI/ASA S12.6 or the insertion-loss data from ANSI/ASA S12.42, nor are
such data suitable for labeling the attenuation of HPDs.
