医院和旅馆的噪声管理

防治噪声污染是为了创造一个安宁、适宜的生活和劳动环境。噪声污染涉及的领域很广,应从各个方面加以控制。然而,由于噪声污染不同于水、气、渣污染,除特强噪声外,一般不会造成致命性危害。就现阶段而言,噪声管理的重点是保护居民的睡眠环境,环保部门按国家标准和地方法规,对污染者征收超标排污费,并限期治理。这方面已经收到明显的环境效益,得到了居民的赞赏。但是,城市中有一类极为重要的睡眠休息环境被遗忘了,这就是医院(包括疗养院)病房和旅馆(包括招待所、饭店、宾馆)客房。     

Evaluation and analysis of environmental noise pollution in the city of Erzurum, Turkey

Noise pollution and its influence on the environment and life quality of human beings is a hot topic in scientific research. A study has been carried out to determine the level of noise and its sources in the city of Erzurum located in the east of Turkey. Noise measurements were taken in the morning, at noon and in the evening to determine noise pollution all over the city, particularly motorway transportation noise. In order to determine the sensitivity of the city people to noise pollution, standard survey studies were also conducted. According to the results, the noise level in Erzurum city centre exceeded allowed values at 96 of 126 measurement points. From the measured noise values, a map of noise pollution was created for Erzurum. Proposed solutions are set out.     

Assessment of noise level due to vehicular traffic at Warangal city, India

In the light of the rapid growth of vehicles and the ill effects due to noise pollution, there is a need to study noise pollution from the transportation point of view. In this study, an attempt has been made to study noise pollution due to vehicular traffic in Warangal city, India. It was observed that noise levels are increasing with increased traffic volume. Studies also revealed that 3-wheelers have a major influence on noise levels. It was found that the noise levels at all the locations studied exceeded the Indian standard ambient noise levels.

Surface Transportation Noise and Its Control

Surface transportation creates most of the noise pollution imposed on our communities today. Reduction of this noise impact requires effective preparation and enforcement of regulations to control noise sources, and methods and locations of operation. At the Federal level, such action has begun, within the limited authority available. Concurrently, research and development programs are demonstrating that means to satisfy noise control regulations are technically practical and economically reasonable. This paper provides a brief review of Federal regulatory areas and corresponding R&D activities pertinent to surface transportation noise abatement.     

室内箱式变压器结构声污染及对策

通过对置于住宅楼底层室内箱式变压器引起的结构声污染进行调查实测，在对箱式变压器结构声传播进行声学分析基础上，提出了切实可行的防治对策，经实际工程应用验证，效果较好。对机房正上方住房主卧内降噪量为5.0dB，室内夜间噪声降为30.2dB，各层住户夜间烦恼度普遍从非常烦恼或烦恼降为有点烦恼和不大烦恼。这从噪声污染控制的角度证明了变配电房置于住宅楼等噪声敏感建筑物室内底层甚至更高楼层在技术上是可行性的。同时也为杭州市正在试点推广的箱式变压器置于噪声敏感建筑物底层提供了实践依据。     

Traffic noise exposure of high-rise residential buildings in urban area

Noise pollution is a major factor of environmental complaints in many cities, which has significant impacts on human health. As a dominating source of environmental noise, the impact of road traffic noise is increasing. Residents living in high-rise buildings along the main road are severely affected by traffic noise. In order to assess the noise level of urban area along the main road in Guangzhou, three buildings were selected to conduct traffic noise measurements, and the questionnaire about traffic noise impact on human being was completed. Through the questionnaire, around 70% of participants consider the traffic noise has negative effect, and about 60% of participants consider the noise has moderate or much higher impact on physical comfort. Around 65% of participants consider the noise had moderately or much higher impact on their psychological comfort. By analyzing the measured data, all of the measured noise levels in three buildings exceed the recommended limit of 55 dB (A) in the daytime and 45 dB (A) in the night for residence, and the exceeded value can be up to 16 dB (A). By comparing the fitting curve of noise level transfer function on each floor relative to the reference floor, the quadratic polynomial was selected to plot the transfer function rather than cubic polynomial.
