摘要
列车高速通过隧道时，由于车内压力变动，旅客会有听觉上的不舒适感。最近，随着非气密化车辆的提速，旅客听觉不舒适感更为突出。本文在参考许多国际研究资料的基础上，制定出非气密性车内压力变动的指标暂定为每４ ｓ不超过２０ ｋ Ｐａ。
Passengers sometimes feel an aural discomfort caused by pressure change when the train passes the tunnels at high speed.Recently,with speedup of the unsealed rolling stock,passengers’ aural discomfort has become more obvious.On the basis of reviewing many international research materials,a provisional guideline for the pressure change in unsealed stock is proposed with setting an index of 2 0 kPa within any 4 seconds period.
