ABSTRACT

The objective of this study is the frequency of the noise source 170 dB level of impulsive soundattenuation performance by earplugs to identify, to analyze the frequency characteristics of a shapeand pattern. The attenuation performance of the impulsive noise by the frequency levels on the CombatArm and 3M Form types 1100 Earplugs were evaluated. In order to check the sound attenuationperformance of the B&K head and torso simulator and sound attenuation performance of the earsimulator data was verified. Previous studies have most impact, even in the noise source and theimpulse noise level is 140 dB, but this study is higher than that of the impulsive noise source features. The results of the impulse noise attenuation effect is frequency-dependent mean 28.58 dB.
