Recently, a technique has been developed which provides precise electronic measurement of ear canal noise levels inside insert hearing protectors. It is intended to be used in the workplace rather than in the laboratory in order to provide an accurate assessment of workplace noise levels that have penetrated insert hearing protectors. The procedure can be used for training to provide instantaneous feedback concerning insertion procedures.
Fit testing is thereby objective.
Employers can utilize the objective data as evidence of effectiveness of hearing protection. Relevance regarding liability in claims will be discussed. This presentation will describe technique and instrumentation in detail. Data will be presented. Impact upon hearing conservation programs will be discussed.
