【摘要】：随着我国经济社会的发展,城市噪声问题愈发突出,但以噪声分贝等级来控制城市噪声已被证实不完全有效。衡量城市声环境品质的要素除噪声等级外,还有很多主客观因素的影响。为此,加拿大R.Murray Schafer提出了声景概念,认为城市中的声音并不仅以噪声形式存在,而是一种声音环境。更确切地说,是一种由声源、空间和人组成的景观。因此,应该运用声景理念来指导城市的声环境建设。华侨城生态广场是一个使用率极高并深受周边居民喜爱的著名社区广场,然而,相关研究表明其声环境品质并不完全满足人们的要求。华侨城社区声景既有好的方面也有不好的方面,在什么样的主客观环境条件下,声景品质如何,针对不同的问题,值得开展深入具体的研究。为此,本论文针对华侨城生态广场这一反应良好的社区公共空间,开展了实地研究,对影响华侨城生态广场声景的主客观影响因素进行了分析,为华侨城生态广场未来的发展做基础性的研究的同时,也为类似社区广场的规划设计在声环境方面的提升提供一定的参考和借鉴。为了解华侨城生态广场的声景状况,采用了问卷调查的方式考察广场使用者的主观评价,并通过现场录音的方式记录使用者被调查时的实时声环境,利用相关声品质分析软件和统计软件对结果进行了分析,并对影响生态广场声景的各主客观因素进行了研究。包括三大部分内容,一是通过对调研样本的分析,确定了华侨城生态广场及其各部分的声源含义、声景安静性及声景舒适性,并对使用者的基本属性进行了初步分析;二是通过对生态广场声源含义即自然声、生活声、机械声组成比例的分析,生态广场声级即Leq、L10、L50、L90的分析,以及生态广场响度、尖锐度和粗糙度等心理声学参数的分析,研究了各客观要素对生态广场声景效果及主观评价的影响;三是通过对生态广场使用者性别、年龄、职业与教育背景及生活环境等社会背景因素的分析和包括活动频率、活动时间在内的活动因素的分析,研究了各主观要素对生态广场声景效果及主观评价的影响。
[Abstract]:With the development of our country's economy and society, the problem of urban noise becomes more and more prominent, but it has been proved that it is not completely effective to control the urban noise by noise decibel level. There are also many subjective and objective factors. For this reason, R. Murray Schafer of Canada put forward the concept of sound scene, which suggests that sound in cities exists not only in the form of noise, but also as a sound environment. Rather, it is a sound source. Therefore, the concept of soundscape should be used to guide the construction of the sound environment of the city. Oct Ecological Plaza is a famous community square with a high utilization rate and is loved by the surrounding residents, however, Relevant studies have shown that the sound environment quality does not fully meet the needs of people. There are both good and bad aspects of the sound scene in the community of overseas Chinese cities. Under what subjective and objective environmental conditions, what is the sound scene quality, aiming at different problems? For this reason, this paper has carried out a field study to analyze the subjective and objective factors that affect the sound scene of the ecological square of overseas Chinese city, aiming at the well-reacted community public space of the ecological square of overseas Chinese city. While doing basic research for the future development of the ecological square in overseas Chinese cities, it also provides certain reference and reference for the improvement of sound environment in the planning and design of similar community squares. In order to understand the sound scene situation of the ecological square in overseas Chinese cities, The subjective evaluation of the square users was investigated by questionnaire, and the real-time sound environment of the users was recorded by live recording, and the results were analyzed by the correlation sound quality analysis software and the statistical software. And has carried on the research to each subjective and objective factor which affects the ecological square sound scene. It includes three major contents. First, through the analysis of the investigation sample, it determines the meaning of the sound source of the ecological square and its parts of overseas Chinese city. The soundscape is quiet and comfortable, and the basic properties of the users are analyzed preliminarily. Secondly, through the analysis of the proportion of natural sound, living sound and mechanical sound, the sound level of ecological square is the analysis of Leqer L10 / L50 / L90, the second is the analysis of the meaning of the sound source of the ecological square, that is, the proportion of natural sound, living sound and mechanical sound. As well as the analysis of the psychoacoustical parameters, such as the loudness, sharpness and roughness of the ecological square, the influence of each objective factor on the sound scene effect and subjective evaluation of the ecological square is studied. Third, through the analysis of the gender and age of the users of the ecological square, Based on the analysis of social background factors, such as vocational and educational background and living environment, as well as the analysis of activity factors including activity frequency and activity time, the influence of each subjective factor on the sound scene effect and subjective evaluation of ecological square was studied.
