FitCheck for Muff-type Hearing Protectors
Recently, FitCheck for Earmuffs has been developed. This is a very simple system, consisting of a Type II sound level meter with a remote microphone that is mounted on an earclip. The microphone is worn on the worker’s ear at his workstation, and the muffs are worn over the microphone. The reading on the sound level meter represents the exposure under the earmuff.
