摘要
目的研究陶瓷厂噪声对作业人员听力的影响。方法采用丹麦GST-68型纯音听力计，测定82例接触噪声工人（噪声组）和48例非接触噪声工人（对照组）的听力。结果测定18个噪声点，噪声强度平均（85．7±6．6）dB（A）[71．4～95．2dB（A）1，其中有15个点超标，超标率88．3％。噪声组听力损失检出率51．22％，明显高于对照组（10．42％），差异有极显著性（P〈0．01）。接触噪声工龄〈3年、3～5年、〉6年组听力损失检出率分别为16．67％、77．14％和81．82％，听力损失检出率随接触噪声工龄的增加而升高，差异有极显著性（P〈0．01）。结论陶瓷企业噪声引起作业工人听力损失，应做好预防工作。
Objective To study the effect of noise to the hearing loss of the workers exposed to noise in a ceramic plant. Methods The hearing examination in 82 noise exposed workers （noise exposed group） in a ceramic plant and 48 non-exposed personnel （control group） were determined by model GST-68 pure tone audiometer made in Denmark. Results 18 points of noise intensities were detected and average noise intensity was（ 85.7 ± 6.6 ）dB（A） and 15 points （88.3%） exceeded the national occupational exposure limits. The incidence rate of hearing loss in the noise exposed group was 51.22%, significantly higher than that in control group （10.42%, P〈0.01）. The duration of noise exposure 〈 3 years, 3 years - 6 years, 〉 6 years were 16.67%, 77.14% and 81,82% respectively. The incidence rate of hearing loss seemed to be increased gradually with duration of noise exposure increasing （ P〈0.01 ）.Conclusion The hearing loss abnormality could be caused by exposure to noise in the ceramic enterprises, precautions and measurements should be implemented.
