Comparison of laboratory protocols for yielding improved estimates of hearing protection in field performance for use in standards development
Federal law requires hearing protection device (HPD) manufacturers to provide attenuation ratings for use in estimating workers’ protection levels. These ratings, which are laboratory obtained, typically overestimate the actual protection levels achieved in the workplace. This research investigated...
