对２９０名接噪组铝矿工与对照组进行了对比分析，接噪组工人０．５～８ｋＨｚ各频段的听阈均明显高于对照组（Ｐ＜０．０１）。两组心电图异常项次比较，接噪组窦性心动过缓、心律不齐和心电图异常改变之和增高明显（Ｐ＜０．０５和Ｐ＜０．０１）。经累积接噪量与患病率相关分析，高频听损、语频听损和高血压的患病率均随累积接噪量增加而升高，呈明显正相关（ｒ＝０．９３８９，ｒ＝０．９９５３和ｒ＝０．９４８７，均Ｐ＜０．０１）。
The comparison of 290 pick-up group miners and the control group was made. The hearing thresholds of 0.5-8 kHz band in workers receiving noise were significantly higher than those in the control group (P <0.01). Electrocardiogram anomalies in the two groups were compared, then noise group sinus bradycardia, arrhythmia and ECG abnormal changes increased significantly (P <0.05 and P <0.01). According to the correlation analysis of accumulated noise and prevalence, the prevalences of high-frequency hearing loss, hearing loss and hypertension were positively correlated with the increase of accumulated noise (r = 0.9389, r = 0.9953 and r = 0.9487, all P <0.01).
