在城市各类噪声源中,道路交通噪声的影响范围最广,一般约占城市环境噪声源的40％左右,并且声级较高,是影响城市声环境的最主要声源。近年来,齐齐哈尔市建设发展很快,拓宽和改造的交通干线相继而成,干线两侧的住宅楼也相应拔地而起。这些变化,对降低交通噪声起到了良好的作用,但对临街住宅的影响却提出了新问题。本文从控制交通噪声的角度出发,在理论和实际测量的基础上,对齐齐哈尔市的交通噪声的影响因素及控制作初步讨论。
Among all kinds of urban noise sources, the impact of road traffic noise is the most extensive, accounting for about 40% of the total urban ambient noise sources and the sound level is high, which is the most important source of sound impact on the urban environment. In recent years, the rapid development of the construction and development of Qiqihar City, broaden and transform the traffic arteries have been formed, both sides of the main line of residential buildings are correspondingly. These changes have played a good role in reducing traffic noise, but new problems have been raised on the impact of residential buildings on the street. Based on the theoretical and practical measurements, this paper discusses the influential factors and control of traffic noise in Qiqihar from the perspective of traffic noise control.
