知(zhi)道了這些(xie)易感因(yin)素(su)，能幫你(ni)有效避免噪聲性聾。1。體(ti)內因(yin)素(su)的影響與體(ti)內神經內分(fen)泌(mi)的改(gai)變(bian)(bian)、高1血壓、脂(zhi)代(dai)謝異常、鎂缺(que)乏、鐵(tie)代(dai)謝障礙(ai)等因(yin)素(su)有關。2。原有聽力損(sun)害及耳(er)病(bing)多數(shu)內耳(er)病(bing)對噪聲更敏感，伴有進(jin)行性聽力下降者應避免進(jin)入噪聲車(che)間工作。中耳(er)傳音機構存在病(bing)變(bian)(bian)，可減(jian)少進(jin)入內耳(er)的能量，從而(er)減(jian)輕(qing)噪聲對內耳(er)的損(sun)傷，但(dan)中耳(er)肌(ji)癱瘓時，反而(er)使內耳(er)更容易遭(zao)受損(sun)傷。
