随着我国铁路客运事业的迅速发展,将会有越来越多的旅客和列车乘务人员经受客车噪声不同程度的影响,而人们的旅行生活条件要求则日盆提高,因此,当前对客车噪声问题应引起足够的重视。为了评价客车噪声对人体的不良影响以及比较各种客车噪声的声学特性和噪声控制效果,我们参照国际标准化组织提供的“3381—1976声学——轨 With the rapid development of China’s railway passenger transport business, more and more passengers and train crew members will experience different degrees of impact on bus noise. However, people’s traveling and living conditions are on the rise. Therefore, Should cause enough attention. In order to evaluate the adverse effects of bus noise on the human body and to compare the acoustic characteristics and noise control effects of various bus noise, we refer to “3381-1976 Acousto-Rail” provided by the International Organization for Standardization
