Abstract
A method for selection of hearing protectors based on attenuation and comfort is presented. For the attenuation, the data provided by the manufacturer are used after being derated. A protector is selected when its attenuation is higher than the measured (or calculated) noise exposure minus the criterion level set by regulations or legislation. When large numbers of workers are involved, group noise exposure and associated standard deviation are to be used. Comfort is assessed by using a specially developed questionnaire. Protectors are distributed to ten workers who have to wear them during an entire shift. The questionnaire is completed prior to and after wearing the protectors.
