用统一印制的接触噪声作业体检册对暴露在80~101DB(A)生产环境中的71名作业者进行调查,听力检查在本底噪声值≤30DB(A)的静室内进行,传导性耳聋加做诱发电位.发现接噪者自觉症状以头昏为最多,头痛、耳鸣次之,其它如胃痛、食欲不振、胸闷等症状各占一定比例;神经衰弱是接噪者明显的主观症状,阳性者39人(54.93％),女(占67.65％)明显多于男(43.24％),稳态组与脉冲组相比差异有显著性;接噪早期有低血压倾向,心电图发现异常较多,但以窦性心律不齐(7.04％)和窦性心动过缓(5.63％)为主;查出噪声性耳聋6人(8.45％),高频听损34人(43.66％),听力图发现脉冲组听力V型下降较稳态组明显,脉冲组平均听损较稳态组大近4DB(A),表明脉冲噪声对人体的听觉系统损害较稳态噪声严重“,”The survey had been carried out for 71 workers in the 80～101dB(A) surrouding according to the examination pamphlet on contact noise work, and the audiometry was done in the silent room with a background noise value ≤30dB(A), and the evoked potential preparation for conduction deafness. Results showed that the major subjective symtoms were dizziness, secondly the headache and tinnitus, and the others such as stomache-ache, anorexia, and chest distress had certain ratio. And 39 individuals (54.93 percent) had...
