Abstract |
Miniature earphones were incorporated into 3 models of hearing protector. Different plates for holding the earphones in the ear-caps of the protectors were tested, and the effect of the plates on the attenuation of noise was determined. Attenuation in various frequency bands for different combinations of earphone, mounting plate and ear-cap was tabulated. Incorporation of earphones did not significantly degrade the performance of the protectors. |
