Abstract
Abstract Noise pollution is one of the main environmental stressors in urban areas. In particular, strong noise pollution can be experienced at nighttime in downtown areas with intense anthropic activities: here, dwellers may suffer from disturbance to their rest, which induces stress and – in turn – adverse effects on health. Usually, local authorities implement actions to tackle noise pollution, e.g. limiting the time allowed for outdoor events. However, these measures are often inadequate because the noise annoyance comes directly by the shouting of people spending time outdoors till late night. In this framework, this study proposes a procedure to optimize the shape of customized lightweight transparent noise screens that can be applied to façades in order to reduce noise disturbance in urban canyons. The case study of the “movida” area in the downtown of Marina di Ragusa (Southern Italy) is discussed to test the applicability of the proposed procedure. The results of this analysis allow defining the shape and the size of the noise screens that minimize the noise annoyance perceived by residents. The proposed mitigation approach can be applied in cities affected by significant noise pollution.
噪声污染是城市环境的主要压力源之一。特别是,在人类活动激烈的市中心地区,夜间可能会受到强烈的噪音污染:在这里,居民可能会受到干扰,无法休息,从而引起压力,进而对健康产生不利影响。通常,地方当局会采取措施解决噪音污染问题,例如限制户外活动的时间。然而,这些措施往往是不够的,因为噪音的烦恼直接来自于人们在户外呆到深夜的喊叫。在此框架下,本研究提出了一种程序来优化定制的轻质透明隔音屏的形状,这种隔音屏可以应用于街面,以减少城市峡谷中的噪音干扰。本文以意大利南部Marina di Ragusa市中心的“movida”区域为例,对所提出的程序的适用性进行了讨论。分析的结果允许定义噪音屏的形状和大小,以最大限度地减少居民感受到的噪音烦恼。建议的缓解方法可适用于受严重噪音污染影响的城市。
期刊介绍:
Ever since its inception, Noise Mapping has been offering fast and comprehensive peer-review, while featuring prominent researchers among its Advisory Board. As a result, the journal is set to acquire a growing reputation as the main publication in the field of noise mapping, thus leading to a significant Impact Factor. The journal aims to promote and disseminate knowledge on noise mapping through the publication of high quality peer-reviewed papers focusing on the following aspects: noise mapping and noise action plans: case studies; models and algorithms for source characterization and outdoor sound propagation: proposals, applications, comparisons, round robin tests; local, national and international policies and good practices for noise mapping, planning, management and control; evaluation of noise mitigation actions; evaluation of environmental noise exposure; actions and communications to increase public awareness of environmental noise issues; outdoor soundscape studies and mapping; classification, evaluation and preservation of quiet areas.
