高架轨道交通低频噪声对居民烦恼度影响研究

针对目前我国城市轨道交通发展中日益凸显的噪声问题,对高架城市轨道交通线路噪声影响沿线居民烦恼度的现状进行了研究。采用社会调查法,在高架城市轨道交通沿线开展了居民主观烦恼度问卷调查以及现场噪声监测,获得了相关主客观数据,并与预测的主观烦恼度相对比。分析研究表明,调查获得的噪声烦恼阈值为53 d BA,大于实际监测噪声,但由于高架城市轨道交通沿线低频噪声较为显著,因此仍能引起沿线居民较大的烦恼反应。

On the Annoyance of Residents along Urban Rail Viaduct Lines Caused by Low Frequency Noise

To study the increasingly serious noise problems caused by urban rail viaduct in Chinese cities,the annoyance of residents along viaduct lines is studied by adopting social survey method and on-site monitoring method,in order to collect questionnaires issued to the residents about their annoyance and the viaduct noise data.The collected subjective and objective data are compared with he predicted annoyance data,the results show that the noise annoyance threshold is about 53 dBA,higher than the monitored data but close to the standard limit.The major reasons that cause residents' annoyance are defined as the low frequency noise along rail viaduct lines.
