| 摘 要： | 重庆市中区８个交通路段等效连续声级为７０．５￣７５．７ＬｅｑｄＢ（Ａ）。２１９名交通警察和１０２人的对照组听力曲线特征为：高频段听力曲线呈Ｖ或Ｕ型凹陷型，交警组明显多于对照组（Ｐ〈０．０１）。高频段呈倾斜型下降两组无差别。双耳听力曲线呈对称性分布、对照组多于交警组（Ｐ〈０．０５）。高频段和语言段听力损伤，交警组明显多于对照组（Ｐ〈０．０１）。

| Abstract: | he levels of road traffic noise were measured in eight main streets of Chongqing city andthe equivalent sound levels were found to be 70. 5-75. 5 LeqdB(A). An exposed group of 219traffic policemen and 102 conntrol subjects, were audiometrically examined.The results showed that the distribution of the audiocurve of both ears appeared to be sym- metric and the V- and U- shape valleys were found at high frequency band among the exposedgroup, which differed remarkably from the controls(P < 0. 01).Meanwhile the prevalence ofhearing loss at high fenquency and speech frequency among the traffic policemen was significantly higher than that of the controls(P<0. 05). |
