Abstract |
A simplified method of selecting ear protectors is presented. It is based on the rating noise level at the workplace, the results of preventive hearing examinations, and the sound attenuation power (as a function of frequency) of the protectors. The method takes into account various elements (differentiation between normal and high-risk individuals with regard to hearing loss, threshold values of 90 and 86dB(A), rating sound level and frequency range of noise under study), and permits the sound attenuation capacity required of the protector to be determined. The wide scatter of attenuation values for a given type of protector is stressed. There is still no appropriate protection for persons at high hearing loss risk exposed to extreme noise conditions. |
