为探讨脉冲噪声与稳态噪声对工人听力损伤的差异，我们对接触脉冲噪声（冲床工、锻压工）工人５６７名，稳态噪声（挡车工、织布工）工人４８２名进行听力检查。平均年龄（３３．３±６．８）岁，接触噪声工龄（１０．７±６．２）年。１方法噪声测试按（工业企业噪声测试规范
In order to explore the difference between the impulse noise and steady-state noise on workers’ hearing impairment, we conducted a total of 567 workers with impulse noise (punch press and forging workers) and 482 workers with steady-state noise (block workers and weaver workers). The average age (33.3 ± 6.8) years, exposure to noise length of service (10.7 ± 6.2) years. 1 Method Noise Test Press (Industrial Enterprise Noise Test Specification
