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。
The effect of wearing noise protection on human body balance in noisy environment was studied. The results show that wearing noise protection can reduce the amount of body movement, is conducive to maintaining the balance of the human body. Although the noise protection device causes discomfort to the human body, it is an effective measure to reduce the noise hazard and maintain the safety. The results also show that the earplugs on the human body is more discomfort than the earmuffs, but in strong noise (80dB (A) above) environment, earbuds with large sound insulation more conducive to the maintenance of human balance, is conducive to job safety. In the forest for portable forestry operations, the anti-noise earplugs worn is very necessary.
