| 摘 要： | 高速磁悬浮列车运行速度高,在近轨道处的噪声不仅声级高,而且噪声作用时间短,使得声突发率高.研究了声突发率的计算方法,并对上海浦东高速磁悬浮列车以432km/h行驶时的噪声进行了测量,计算得到在磁悬浮桥架下和距离磁悬浮30m处的声突发率分别为18dB/s和40dB/s.在对应的问卷调查中,75%的居民反映经过磁悬浮桥下时会被磁悬浮噪声"惊吓",13.5%的居民抱怨会"头疼",高速磁悬浮列车产生的高声突发率的噪声严重影响了居民生活.

| Abstract: | Sound onset rate of high-speed maglev is defined in the article; it increases as speed increases for a given distance,and decreases as distance increases for a given speed.At the speed of 432 km/h at Shanghai Pudong,onset rate is 18dB/s and 40dB/s at the distance of 30m to maglev track and under the viaduct track. 88.5% of the inhabitants along the maglev track complainted that they were startled when they past by the maglev track in the survey of correspondence. |
