| 中文摘要 |
| 参照国家环境噪声标准,在西山官地矿,选择了噪声在50dB(A)以上和50dB(A)以下两类居民区,对16岁以上的居民选256名为本次调查对象。监测结果,户外最高为75dB(A),户内最高为63dB(A),均超过国家规定标准。在50dB(A)以上的环境下生活、工作和学习的居民神经系统和听力均有不同程度的损伤,而且损伤程度与居住年限有密切关系。神衰阳性率10年以上者。50dB(A)以上为34.28%,50dB(A)以下为13.55%;语频听损检出率50dB(A)以上者,10年以上为34.79%,10年以下为29.59%.经统计学处理,均有显着性差异,P<0.05。 |
| 英文摘要 |
| To refer to PRC'S standard for environmental noise, two groups of population which exposed to the noise above 50 dB (A) and below 50 dB (A) were selected from Guandi coal mine in western mountain region, Taiyuan, and 256 men above 16 years old were taken as the investigative subjects in this study. The results of measurement were that the greatest values of environmental noise measured outdoor and indoor were 75 dB(A) and 63 dB(A),respectively. All of these values have exceeded the PRC's standard for environmental noise.Therefore, the results shown that living, working and studing under this condition have injuried effects on population's nerve system and hearing to a cerium extent and the injury extent was associated closely with living-years. The possitive rate of neurasthenis in population living for above 10 years and exposed to above 50 dB (A) was 34.28%,while that exposed to below 50 dB (A) was 13.35%, the hearing injury of voice frequency in population living for above 10 years and exposed to 50 dB(A) was 34.7% while that living for below 10 years was 29. 59% and there were statistically significant differences between both above at P<0.05. |
