| Abstract |
Results of tests conducted at the research centre of INRS (the French National Research and Safety Institute) on 8 earmuff-type hearing protectors from 4 French suppliers. The equipment was tested on a manikin according to the draft international standard ISO DIS 6290. Results are presented in the form of data sheets that show attenuation curves as functions of sound level for different standard frequencies and for typical noise in the middle of the frequency range. Method for calculating the daily noise exposure of a worker wearing hearing protection and exposed to various types of noise during the day. |
