Abstract

Abstract One of the adverse effects of industrialization is noise pollution, which disturbs the mental health and tranquility of urban residents and is the source of numerous social tensions. Twenty stations in the central areas of Almaty with varying uses during the morning, afternoon, and evening rush hours were measured for this study. The objectives of this paper include determining sound indices, identifying potential sound sources, and calculating the relative contribution of each to the overall urban noise level. Additionally, 400 questionnaires were distributed to individuals to assess noise pollution’s effects on individuals. The average maximum value of TNI (Traffic Noise Index) in residential and commercial use is 85.4 dB(A), and the maximum value of Leq (Equivalent continuous sound level) in commercial use is 86 dB(A). In addition, 50 city bus drivers were examined to determine the impact of noise in this environment. The results revealed that as Leq increases, the number of unsafe acts increases. The questionnaires revealed that people are significantly more dissatisfied with noise pollution at stations with higher sound levels.

确定哈萨克斯坦阿拉木图市中心地区的噪声污染参数

摘要工业化的不利影响之一是噪音污染，它扰乱了城市居民的心理健康和安宁，是许多社会紧张局势的根源。本研究对阿拉木图市中心地区的20个车站进行了测量，这些车站在早上、下午和晚上的高峰时段具有不同的用途。本文的目标包括确定声音指数，识别潜在的声源，并计算每种声源对城市总体噪声水平的相对贡献。此外，还向个人发放了400份问卷，以评估噪音污染对个人的影响。住宅和商业用途的TNI（交通噪声指数）平均最大值为85.4dB（A），商业用途的Leq（等效连续声级）最大值为86dB（A）。此外，对50名城市公交车司机进行了检查，以确定噪音在这种环境中的影响。结果显示，随着Leq的增加，不安全行为的数量也在增加。调查问卷显示，人们对声音水平较高的车站的噪音污染更加不满。

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.
