Problems of the real world sound attenuation of hearing protectors with respect to the peak sound pressure level

摘要

The limitation on the exposure to peak sound pressure levels imposed by law has been considerably restricted by the revised version of the directive 2003/10/EC on the minimum safety requirements regarding the exposure of workers to the risks arising from physical agents (noise). The previous Noise Directive 86/188/EC contained only one peak sound level limitation at p_(peak) = 200 Pa as an action level which required the implementation of technical measures to reduce the noise. In the case of exceeding this action value hearing protectors were to be used and the programme of noise reduction measures ought to be established.
