【摘要】 随着我国社会经济的迅速发展和城市化进程的不断加快,社会生活噪声已在很多城市取代交通噪声和工业噪声上升为最主要的噪声源,以前以人群活动噪声为主,而现在城市公共建筑以及高层住宅中的各类动力设备噪声,已成为最重要的社会生活噪声源,这些噪声以中低频成分为主。为了了解低频噪声烦恼度影响及其对行为等的干扰,本文从分析城市居住区低频噪声的特性出发,在调查城市噪声源的基础上,采用调查问卷方法着重研究了两种有代表性的低频噪声烦恼度以及对人的行为的干扰。 本文对城市居住小区公共建筑及高层住宅楼内配套设备固定噪声源(地下车库、变配电房、水泵房、空调机房等)及室内噪声进行了监测,通过频谱分析方法找出以低频成分为主的噪声源,为进行低频噪声烦恼度的调查研究提供了可靠的基础;对存在低频噪声源的居住区进行了主观反应的调查,分析了低频噪声的烦恼度以及低频噪声对人的主观生理感受影响程度等,并与以中高频成分为主的交通噪声烦恼度及交通噪声对人的主观生理感受影响程度进行了对比与分析。 研究结果表明:居住区低频低噪声引起的烦恼度不容忽视,在低频低噪声环境下仍能引起较高的烦恼概率;低频低噪声对人的睡眠、行为及主观生理不适感有影响;低频噪声烦恼度与中高频噪声烦恼度的研究结果在对睡眠、工作及休息上有差异。这些研究工作为今后更加深入和全面地研究居住区低频噪声烦恼度及其评价标准问题提供基础资料。更多还原

【Abstract】 With the economic developing and the rapid process of urbanization in China, the social activity noise has become main noise, instead of traffic noise and industrial noise. On the other hand, all sorts of equipments in residential areas have taken the place of people’s activities to become the most important social activities noise source. Much of facility noise is low frequency noise. In order to find out the annoyance of low frequency noise, the subjective physiology feeling influence and action disturbance , the characteristic of low frequency noise was analyzed in this paper and the method of the public questionnaire was adopted to study the annoyance of low frequency noise.In the paper the noise source was measured in urban residential area such as underground garage, transformer room, water pump room and air conditioning system etc. By the frequency spectrum analysis the low frequency noise sources were found. According to analysis finally the survey’s place was chosen. Distributing of urban noise and the annoyance of low frequency noise was surveyed.The results show that the annoyance of low frequency noise residential area should be taken into account. Low-level noise can cause higher probability of subjective annoyance. It’s very slightly to people’s health, sleeping and working about the low frequency noise. It was compared with the high frequency noise caused by traffic about sleep, work and rest. This is the basis of the research of low frequency noise annoyance and its evaluation criterion completely in urban community in the future.更多还原
