Abstract:
Traffic noise on city roads has been seriously influencing the health of inhabitants.In this paper,some city installations environment such as overbridges and buildings were cited to analyse their influence on the reflection of traffic noise,and a resolution to reduce traffic noise was put forward.Keywords:

The situation of Beijing city’s traffic noise was analyzed,and the solutions in urban planning,traffic and environmental management were put forward.It was emphasized to rationally plan roads and bulidings.The methods of anti noise by using insulation windows and green plants were encouraged,at the same time,it is very important to further enhance our management.

Based on the data of regional environmental noise and roadside traffic noise in Taiyuan City in the years from 1996 to 2000,the average level of noise and the rate of reaching standard are analyzed as well as the noise distribution in different sections of the roads which are exposed to different noise levels. Through analyzing the distribution of noise sources,it is pointed out that living noise and traffic noise are the primary noise sources of the regional environmental noise of Taiyuan City. Although the numbers of the automobile increase rapidly during these years,the roadside traffic noise has been up to the State Standard owing to the contribution of the road construction. The treatment countermeasures are discussed such as strenghening the research on the city planning,promoting actively the environmental education of general public.

City traffic noise is the widest range of impact, the biggest strength of environmental noise in the present city. It should be regarded as the important work for government to reduce the noise and improve the sound quality of the environment around the city. According to current international conception of residential acoustical environment protection, which is the important branch of living environment, this paper put forward several important works in this system, in the meanwhile , take an active effect for city traffic noise impact assessment work in future.

Life noise,industrial noise and traffic noise are three of the main noise sources in Huai'an City,in which traffic noise is the primary reason for noise pollution.Based on analyzing the present situation of traffic noise in Huai'an City,several noise control concepts are proposed from the aspects of traffic noise concentration,reasonable choice of line and form,types and distributions of the buildings near main roads,and traffic noise management,in hope of changing the way of controlling traffic noise from passive to active,and promoting sustainable urban development.

Due to constant increase in population and traffic volume, traffic noise control in urban areas today represents a major issue for the city authorities. This problem is particularly pronounced in densely built downtown areas, with many residents occupying high-rise buildings which are often placed next to major traffic routes. In order to assess the impact of traffic noise and implement effective measures against it, noise maps of verified reliability must be produced for analyzed area. This paper describes the analysis of traffic noise situation in residential area located in the vicinity of Western railway station in the centre of Croatian capital city Zagreb. The location was selected for several reasons: to determine noise levels that are generated from heavy road, rail and tram traffic with complex traffic conditions in residential downtown area, to investigate the applicability of European interim noise prediction methods in local urban conditions, to study the possible effects of noise reduction measures and also the effect of planned infrastructure on the environment. For the purpose of this analysis, noise models were produced and verified with short-term field measurements. Calculations were conducted by means of noise prediction software, using European interim noise prediction methods and 3D model of analyzed area. Finally, the results of noise calculations for existing and planned traffic infrastructure are presented on noise maps.

With the rapid development of economy,the effects of traffic noise pollution to the environment and our health attract more and more attention.Xiongchu Road is an important highway of the Cultural City in the city of Wuhan.The environment noise value should follow the first class standard when carrying out the fourth class standard.This article systematically surveys traffic noise along Xiongchu Road,and uses the ratio-foretelling method to foretell the developing tendency of the traffic noise in the coming five years,and discusses its countermeasures.

Road traffic is a major source of in urban areas with far-reaching and wide-range effect to human. It produces disturbance and inversely impacts more than other forms of noise. Urban traffic noise impact assessment has thus become an active environmental acoustics domain. This paper firstly measures the traffic noise in the truck lines in Nanchang city and estimates it. Then this paper finds out the cause of the traffic noise in Nanchang city. Thirdly this paper gives some suggestions on the noise pollution.

The sources of urban traffic noise, as well as causes of various noises were introduced. Control measures of urban traffic noise were proposed. According to the mechanism of the noise, control the noises of road traffic and rail traffic from the following respective aspects, running vehicles, road pavement, surrounding environment, national laws and regulations etc. It is possible to provide references for relevant departments to formulate laws and regulations related to vehicle noise and city municipal building.
