Individual hearing protection devices (HPD) are often the first line of defense against noise-induced hearing loss (NIHL) in the workplace. Unfortunately, the real-world attenuation offered by HPDs greatly differs from the laboratory ratings, for many reasons that are now well understood. Mostly, these are related to the proper fit of a given HPD by an individual user. To better assess this fit and predict the effective individual attenuation, Field Attenuation Estimation Systems (FAES) have…

Individual fit testing of HPD will allow the determination of H PD performance on individual workers, and this will improve the ability to select HPD appropriate for given noise exposures and intervene with workers to ensure sufficiency in HPD performance.

ASSESSMENT OF THE PERFORMANCE OF HEARING PROTECTORS FOR HEARING CONSERVATION PURPOSES

Real world methods of field performance evaluation of hearing protection performance will be reviewed and contrasted to the laboratory techniques, and key points illustrated with representative data are illustrated.

Methods of fit testing hearing protectors, with representative field test data

The ability to properly assign hearing protectors in critical high-noise environments or even for lower noise levels when one wishes to closely match attenuation to actual exposure, is questionable.

The ANSI standard S12. 68-2007 method of estimating effective a-weighted sound pressure levels when hearing protectors are worn: A canadian perspective

The Canadian ANSI standard S12.68-2007 method has been developed as a method of estimating effective A-weighted sound pressure levels after wearing hearing protective devices (HPD). The two
