脉冲噪声是不同于连续噪声的一种特殊噪声.它不仅存在于军事领域,工业部门也较多见,爆破,冲床、铆工、锻工,锤工和钻工等工种都有脉冲噪声源.据资料,美国有460万人在高强度脉冲噪声下工作,估计我国直接或间接暴露该噪声环境的人员远超出此数值.值得注意的是,在不少连续噪声环境中,混杂着脉冲噪声成份,往往被人们忽视.和连续噪声相比,脉冲噪声对听力的损害在性质和程度上都不同,甚至吏为严重.因此,研究脉冲噪声及其对听力的影响是噪声领域中一个重要课题.
Impulsive noise is a special kind of noise that is different from continuous noise, which not only exists in the military field, but also in the industrial sector. There are impulse noise sources in such industries as blasting, punching, riveting, forging, hammering and drilling. According to statistics, 4.6 million people in the United States work under high-intensity impulsive noise, and it is estimated that the number of people directly or indirectly exposed to the noise environment in our country far exceeds this figure. It is worth noting that in many continuous noise environments, impulsive noise components , Often overlooked by people.Compared with continuous noise, the impaired hearing impulses of impulse noise are different in nature and extent, even the officials are serious.Therefore, the study of impulse noise and its impact on hearing is an important issue in the field of noise.
