Current Perspectives on Issues in Personal Hearing Protection
Significant criticism of current standard methods of measuring the effectiveness of hearing protectors and, in particular, the NRR scales.
The lack of an adequate artificial head and ear on which to make standard measurements of protectors, which bear some relationship to real life.
The extremely wide range of attenuation provided to the work force by a variety of theoretically appropriate protectors.
The discrepancy between attenuation obtained in the laboratory and that found in field tests.
The relative paucity of information about the effectiveness of hearing protectors in protecting a noise exposed population from hearing loss.
Problems related to communication while wearing ear protectors, including the perception of warning signals.
Difficulty related to wearing multiple protectors.
