The method for evaluating the noise attenuation characteristics of hearing protectors is based on laboratory tests. However, many studies have shown that the actual effectiveness of this protective equipment is, more often than not, much lower than the results thus obtained. The authors examined the time evolution of the performance of this equipment during one work shift, with 24 workers, in different sound environments. This mainly enabled them to develop a method for measuring the real effectiveness of earmuffs and moulded ear plugs, and then to compare it to measurements taken in the laboratory.
