Abstract

A pair of modified dosimeters were used to measure the equivalent noise exposure level inside and outside an earmuff simultaneously. The difference of the two measurements was the index of attenuation. In the present study the effect of hair, glasses, or cap on the performance earmuffs was examined with this method of comparative measurement. It was found that although the effect of hair, glasses, or a thin cap was significant in the reduction of attenuation, the amount was usually no more than 5 dB.
