【摘要】 研究了在噪声环境中,佩带噪声防护具对人体平衡的影响。结果表明,噪声防护具的佩带可减小人体动摇量,有利于人体平衡的维持。虽然噪声防护具给人体造成不适感,但却是减少噪声危害、维护安全的有效措施。研究结果还表明,耳塞对人体的不适感大于耳罩,但是在强噪声(80dB(A)以上)环境下,隔声量大的耳塞的佩带更有利于人体平衡的维持,有利于作业安全。在林区进行便携式林业机械作业时,防噪声耳塞的佩带非常必要。更多还原

【Abstract】 In this article, an experimental study was carried out on effects of hearing protection device(HPD) on body sway in the noise environment.The results indicated that the using of the HPD can reduce the body sway in noise environment, if has positive effect on body balance. Using of HPD made workers a little discomfort, but it is effective methods to reduce noise and maintain the body balance. The experimental results indicated that using of ear plug was more discomfort than using ear muff, but in strong noise environment(higher than 80dB(A)) , ear plug had better effect on body balance. So it is very necessary to use HPD (especially ear plug) while operating portable forest machine.更多还原
