METHODE DE MESURES TERRAIN DE L'ATTENUATION F-MIRE DE PROTECTEURS AUDITIFS DURANT UN QUART DE TRAVAIL

摘要

Nowadays, hearing protection devices (HPD) are widely used to protect workers against industrial noise, however, a question worth examining is: "Is the workei truly provided with, at all times, protection that is as effective as what the manufacturer is advertising, based, on standardized testing?" It is a commonly known and well documented fact that compared to values obtained from various existing field studies laboratory-measured noise attenuation values overestimate the actual protection being provided to workers. Too few studies are available on this topic, and the issues concerning HPD field measurement are still far from being resolved. Even if several field measurement methods have been developed, none has succeeded in being recognized as a standard. Therefore, the need for a new field measurement method, one which could become a recognized reference, is as relevant as ever.
