本文报道了三个织布车间环境噪声的强度为101～104分贝。通过1,091名布机间工人的听力损失程度的测定,发现工作半年后即可有持久性听力损失,以后随工龄的增长而加重,有成为耳聋者.一般经工后休息,听力可有显著恢复,但仍有一定程度的耳聋。听力损失的频率,在不同噪声频谱的影响下有所不同。在织布车间首先是损失高频听力,而在纡子车间主要是语频听力.采用玻璃棉制的耳塞,能保护听力不受损伤.
The paper reports the intensity of environmental noise in three weaving workshops is 101 ~ 104 dB. Through the survey of the level of hearing loss among 1,091 workers, it was found that there was permanent hearing loss after half a year of work, and later with the increase of seniority, there were those who became deaf. Generally, after-hours rest, hearing could be significantly recovered , But there is still a certain degree of deafness. The frequency of hearing loss is different under the influence of different noise spectra. In the weaving workshop, the first is the loss of high-frequency hearing, while the prickly heat in the workshop is mainly audio frequency hearing. The use of glass wool earplugs, can protect the hearing from damage.
