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。
In view of the increasingly prominent noise problem in the development of urban rail transit in our country, the status quo of residents’ annoyance along the elevated urban rail transit lines is studied. Using the social survey method, residents’ subjective annoyance questionnaire survey and on-site noise monitoring were carried out along the elevated urban rail transit, obtaining relevant subjective and objective data, and compared with the predicted subjective annoyance. The analysis shows that the threshold of noise disturbance obtained by the survey is 53 d BA, which is larger than the actual monitoring noise. However, due to the low frequency noise along the elevated urban rail transit, the troubles caused by the survey are still quite troublesome.
