||Results of tests performed by the research centre of INRS on tightly-fitting acoustic helmets provided by 4 French manufacturers. Testing was by means of an artificial ear, following ISO standard DIS 6290. Results are presented in tables and graphs, showing sound attenuation as a function of the external sound level in different frequency bands, as well as for a typical noise with a preponderance of medium frequencies. Method to follow for the calculation of daily exposure to noise by a worker wearing a helmet and exposed to several types of noise during the day.
