脉冲性噪声是工业生产中常见的一类生产性噪声,主要接触工种有冲压工、铆焊工、剪板工等,多见于机械加工行业[1]。为评价脉冲噪声对作业工人听力及心血管系统的影响,我们选择了212名某企业接触脉冲噪声和其他企业202名接触稳态噪声工人,对其听力及心电图、血压情况进行分析如下 Impulsive noise is a common type of industrial production of noise, the main contact with the type of stamping workers, welding workers, shears, etc., more common in the machining industry [1]. To evaluate the impact of impulsive noise on the hearing and cardiovascular system of workers, we selected 212 exposure impulse noise from one company and 202 workers exposed to steady-state noise from other companies, and analyzed their hearing, electrocardiogram and blood pressure as follows
