Abstract The problem of noise pollution in Baghdad, the capital city of Iraq, is getting worse every day as a result of the increased volume of traffic. This presents a considerable risk, particularly on the main roads that connect densely populated neighborhoods such as the Al-Sadr City district with the central neighborhoods of the capital. In order to inform decision-makers in urban development and environmental policy about the high values of noise pollution that require remediation and regulation, noise maps are produced. However, two fundamental problems are generally faced in creating a more reliable noise map in the shortest possible time: the excessive time requirements for measuring noise and determining the method of map creation. Therefore, the role of geographic information system (GIS) software in producing noise maps is evident due to the difficulty of increasing the spatial density of measurements and integrating them with spatial information. Hence, an appropriate interpolation method is required. In this article, Moran’s I index was calculated to assess the spatial autocorrelation of measured traffic noise points. A comparison was made between the Smart Map Plugin ordinary kriging (OK) and the inverse distance weighting (IDW) deterministic interpolation method to determine the best method for producing noise maps for the main entrance and exit roads of Al-Sadr City. The noise values were modeled using the best-performing method. Furthermore, the predictive raster data are displayed in the spatial context as a starting point and reference for identifying and understanding the levels of traffic noise in the selected study area. The locations of selected points for measuring traffic noise values were determined in an organized and homogeneous manner, where noise points for the main entrance and exit roads were opposite each other, and the distance between consecutive noise points on each road was 100 m. Traffic noise measurements were carried out at each selected point using the SVAN977 sound and vibration analyzer. At each measurement point, three noise values (LAeq, Max, Min) were obtained during the three peak times, 7–9 AM, 12–2 PM, and 4–6 PM. QGIS software was used to compare the two interpolation methods, with its strength lying in the use of plugins that facilitate spatial analysis, processing tools, and algorithms. The Smart Map Plugin provided facilities to choose the appropriate semi-variogram in the OK interpolation method. The root mean square error was used to compare the two interpolation methods in order to determine the most suitable method for producing traffic noise maps in the study area. The results indicated that the Smart Map Plugin using OK outperformed the IDW method, as spatial distribution pattern and homogeneity affect the accuracy of interpolation. Moreover, based on the analysis of the three noise attributes (LAeq, Max, Min), the performance of the Smart Map Plugin (OK) was found to be better than IDW
伊拉克首都巴格达的噪音污染问题日益严重,这是由于交通流量的增加。这带来了相当大的风险,特别是在连接萨德尔城区等人口稠密社区与首都中心社区的主要道路上。为了使城市发展和环境政策的决策者了解需要补救和管制的高价值噪音污染,制作了噪音地图。然而,在尽可能短的时间内创建更可靠的噪声图通常面临两个基本问题:测量噪声和确定绘制方法的时间要求过高。因此,地理信息系统(GIS)软件在产生噪声地图中的作用是显而易见的,因为很难增加测量的空间密度并将它们与空间信息相结合。因此,需要一种合适的插值方法。本文通过计算Moran’s I指数来评价实测交通噪声点的空间自相关性。通过对智能地图插件普通克里格法(OK)和逆距离加权法(IDW)确定性插值法的比较,确定了制作萨德尔城主要出入口道路噪声地图的最佳方法。采用性能最好的方法对噪声值进行建模。此外,预测栅格数据在空间背景下显示,作为识别和理解选定研究区域交通噪声水平的起点和参考。选取的交通噪声测量点位置采用组织均匀的方式确定,主要出入口道路噪声点相对,每条道路连续噪声点之间的距离为100 m。在每个选定点使用SVAN977声音和振动分析仪进行交通噪声测量。在每个测点,分别在上午7-9点、下午12-2点和下午4-6点三个峰值时间获得三个噪声值(LAeq、Max、Min)。使用QGIS软件对两种插值方法进行比较,其优势在于使用了便于空间分析、处理工具和算法的插件。智能地图插件提供了在OK插值方法中选择适当的半变异函数的工具。利用均方根误差对两种插值方法进行比较,以确定最适合研究区域的交通噪声地图制作方法。结果表明,使用OK的智能地图插件优于IDW方法,因为空间分布格局和均匀性影响插值精度。此外,通过对LAeq、Max、Min三个噪声属性的分析,发现当Moran’s I值较高时,智能地图插件(OK)的性能优于IDW。

Abstract Noise pollution, a man-made disaster in the present times, is becoming more severe and pervasive than ever before due to rapid urbanization, affecting quality of life in urban areas in India. Transit areas generate excessive noise which proves disastrous to human health. However, very few studies have mapped noise levels of transit terminals in India. The objectives of this study are (i) assessment of noise levels in Ganeshpeth Bus Terminus, the major interstate bus terminus in Nagpur and generation of noise contour map in ArcGIS and (ii) a qualitative assessment of the impact of traffic-related noise on the health of the people working in the terminus with prolonged exposure to noisy environment, by conducting a health perception survey based on a questionnaire comprising indicators of health parameters. This is a first-of-its-kind study on noise mapping at an interstate bus terminus in India. The results indicate that the noise levels all over the bus terminus site are much higher than the prescribed standards and the source of noise is not only the plying of vehicles but also the misuse of the public address system. Solutions have been suggested to achieve a drastic reduction in noise levels through simple planning-oriented measures.
摘要噪声污染是当今时代的一种人为灾害,由于快速的城市化,它比以往任何时候都更加严重和普遍,影响了印度城市地区的生活质量。过境地区产生的噪音过大,对人类健康造成灾难性影响。然而,很少有研究绘制出印度中转站的噪音水平图。本研究的目的是(i)评估那格浦尔主要州际巴士总站Ganeshpeth巴士总站的噪音水平,并在ArcGIS中生成噪音等值线图;(ii)定性评估交通相关噪音对长期暴露在噪音环境中的总站工作人员健康的影响,通过基于包括健康参数指标的问卷进行健康感知调查。这是印度首次在州际巴士总站进行噪音测绘研究。结果显示,整个巴士总站的噪音水平远高于规定的标准,而噪音的来源不单止是车辆往来,更是滥用公共广播系统。有人提出了通过简单的规划导向措施大幅降低噪音水平的解决方案。

Abstract The modeling of traffic noise is more debated around intersections due to traffic flow and road geometry complexity. The available intersection-specific traffic noise models cannot be transferred to predict the traffic noise at intersections in the mid-sized Indian cities due to traffic heterogeneity, variety in driving conditions, and vehicle compositions. This article aims to develop an intersection-specific traffic noise model by collecting data at 19 intersections in Kanpur, India. The data include a wide range of traffic, road, and weather-related variables. Furthermore, significant input variables are determined and used in the statistical regression model to develop an intersection-specific traffic noise model for the mid-sized Indian cities. This study develops a separate entrance and exit arm model based on the corresponding influencing variables. The coefficient of determination (R 2) value is 0.74 and 0.69 for the developed model at the entrance and exit arms, respectively, whereas these models achieve R 2 values of 0.73 and 0.67 in the validation step. Also, the performance of developed models is evaluated on the standard and mean absolute errors as performance metrics. This study finds that traffic volume and receiver distance are relatively the most important variables in the entrance and exit arm noise models.
由于交叉口交通流和道路几何的复杂性,交通噪声的建模问题一直备受争议。由于印度中等城市的交通异质性、驾驶条件的多样性和车辆组成,现有的交叉口特定交通噪声模型不能用于预测印度中等城市交叉口的交通噪声。本文旨在通过收集印度坎普尔19个十字路口的数据,开发一个特定于十字路口的交通噪声模型。这些数据包括各种交通、道路和天气相关的变量。此外,确定了重要的输入变量,并将其用于统计回归模型中,以开发针对印度中型城市的十字路口特定交通噪声模型。本研究基于相应的影响变量建立了独立的进出口臂模型。开发的模型在入口臂和出口臂的决定系数(r2)值分别为0.74和0.69,而在验证步骤中,这些模型的r2值分别为0.73和0.67。同时,以标准绝对误差和平均绝对误差作为性能指标,对所开发模型的性能进行了评价。研究发现,在进出口臂噪声模型中,交通量和接收距离是相对最重要的变量。

Abstract The civil security sirens are used by the authorities in a wide range of countries to signal an imminent or ongoing threat. Even if their sound level is known, it is nevertheless difficult to evaluate their audibility across a given zone, especially in complex urban environments. An experimental protocol was deployed around a siren installed in a town in France, to assess its audibility perceptually and through modeling. Sound level measurements during source activation were made with the NoiseCapture smartphone application at different distances and on several axes by a group of 25 participants. They were also asked to fill in a questionnaire on perceptual information about the siren such as its audibility, the perceived sound level, or the masking of the siren by passing vehicles. A comparison between acoustic measurement levels using NoiseCapture and simulated sound levels using NoiseModelling was performed. The results of this study validate the use of the Common Noise Assessment Methods in Europe model to evaluate the audibility of a warning system located in an urban environment within a radius of 2.8 km around the siren. Finally, a metric linking audibility to modeled sound level is proposed, enabling the development of siren audibility maps in the study area.
摘要民用安全警报被许多国家的当局用来表示迫在眉睫或持续的威胁。即使它们的声音水平是已知的,也很难评估它们在特定区域的可听性,尤其是在复杂的城市环境中。在法国一个城镇安装的警报器周围部署了一个实验方案,通过感知和建模来评估其可听性。由25名参与者组成的小组使用NoiseCapture智能手机应用程序在不同距离和多个轴上测量声源激活期间的声级。他们还被要求填写一份关于警笛感知信息的问卷,如警笛的可听性、感知的声音水平或过往车辆对警笛的掩蔽。对使用NoiseCapture的声学测量水平和使用NoiseModeling的模拟声音水平进行了比较。本研究的结果验证了使用欧洲通用噪声评估方法模型来评估位于2.8半径范围内的城市环境中的警报系统的可听性 警笛周围公里处。最后,提出了一种将可听性与建模声级联系起来的度量,从而能够在研究区域开发警笛可听性图。

Abstract Public health measures during the COVID-19 pandemic provided researchers with a quasi-experimental situation to examine what happens when anthropogenic noise sources (e.g., traffic) are greatly reduced. This article combines noise-related calls to Montreal’s 311 service (29,891 calls from 2014 to 2022) with original survey data from 240 residents collected in 2020 after the lockdown and the summer reopening. The spatial analysis of the calls revealed that, across all pandemic phases, noise complaints increased with population density, the proportion of low-income residents, and the proportion of greenspace. However, the change in the spatial distribution of noise-related calls due to the pandemic measures is positively associated with the proportions of residential and greenspace land use. That is, areas with higher proportions of residential land use and greenspace experienced the greatest increase in noise-related calls. The analysis of the survey revealed that the sounds of traffic and construction decreased during both the lockdown and the subsequent reopening, while the sounds of the neighborhood and nature increased. However, the decreased traffic noise in the downtown core also allowed for the emergence of noise from the heating, ventilation and air conditioning systems in the area. We discuss these results considering the interest in reducing noise levels in cities.
摘要新冠肺炎大流行期间的公共卫生措施为研究人员提供了一个准实验情况,以研究当人为噪声源(如交通)大幅减少时会发生什么。本文将蒙特利尔311服务的噪音相关电话(2014年至2022年为29891个电话)与2020年封锁和夏季重新开放后收集的240名居民的原始调查数据相结合。对电话的空间分析显示,在所有疫情阶段,噪音投诉都随着人口密度、低收入居民比例和绿地比例的增加而增加。然而,由于疫情措施,与噪音相关的呼叫的空间分布变化与住宅和绿地土地使用的比例呈正相关。也就是说,居住用地和绿地比例较高的地区,与噪音相关的电话增加最多。调查分析显示,在封锁和随后的重新开放期间,交通和建筑的声音都有所减少,而社区和自然的声音则有所增加。然而,市中心交通噪音的减少也使得该地区的供暖、通风和空调系统产生了噪音。考虑到人们对降低城市噪声水平的兴趣,我们讨论了这些结果。

Abstract Visualisation of road traffic noise is vital for traffic noise planning policies. Several factors affect the noise from road traffic with physical and environmental conditions. Collecting noise levels around the world is not a possible task. Therefore, calculating noise levels by a valid noise model, and spatial interpolations, is prime to traffic noise visualisation. In this study, the Henk de Klujijver noise model is used. Designing noise observation points (Nops) embedding with a three-dimensional (3D) building model and identifying the best suitable spatial interpolation are important to visualise the traffic noise accurately. However, interpolating noise in 3D space (vertical direction) is a more complex process than interpolating in two-dimensional (2D) space. Flat triangles should be eliminated in the vertical direction. Therefore, the structure of Nop has a major influence on spatial interpolation. Triangular Irregular Network (TIN) interpolation is more accurate for visualising traffic noise as 3D noise contours than Inverse Distance Weighted and kriging. Although kriging is vital to visualise noise as raster formats in 2D space. The 3D kriging in Empirical Bayesian shows a 3D voxel visualisation with higher accuracy than 3D TIN noise contours.
摘要道路交通噪声的可视化对于交通噪声规划政策至关重要。影响道路交通噪声的因素包括物理和环境条件。收集世界各地的噪音水平是不可能的任务。因此,通过有效的噪声模型和空间插值来计算噪声水平是交通噪声可视化的首要条件。在本研究中,使用了Henk-de-Klujijver噪声模型。设计嵌入三维建筑模型的噪声观测点并确定最合适的空间插值对于准确地可视化交通噪声非常重要。然而,在3D空间(垂直方向)中插值噪声是比在二维(2D)空间中插值更复杂的过程。应消除垂直方向上的平三角形。因此,Nop的结构对空间插值有着重要的影响。三角不规则网络(TIN)插值在将交通噪声可视化为3D噪声轮廓方面比反向距离加权和克里格更准确。尽管克里格法对于将噪声可视化为2D空间中的光栅格式至关重要。经验贝叶斯中的3D克里格显示了比3D TIN噪声轮廓具有更高精度的3D体素可视化。

Abstract Noise pollution in the mining industry has become a serious concern in recent years and has aroused extensive health complaints for the mine workers. Despite the increasing knowledge of the association between noise exposure and health effects, only a few studies have investigated the adverse health effects due to noise pollution in the mining industry. The present study aims to determine the interrelationship of mining noise (MN), demographic characteristics (DC), noise sensitivity and noise annoyance (NA) with subjective health complaints (SHC). A PLS-SEM approach has been used to assess the direct and indirect relationship between the influencing factors on the SHC of 272 people in the mines. Field measurements were made using a sound level meter to evaluate the ambient noise levels for 1 h duration during day and night hour shifts in Dhansar and Bastacolla mining areas of the Jharia coalfield. The noise maps revealed that most of the locations have noise levels higher than 70 dB(A). The statistical model suggests that NA is the most important predictor of SHC. Besides, DC and MN induce only indirect effect on SHC. The study shall facilitate in developing a decision support tool for the assessment of noise levels, induced annoyance, SHC, and suitable policy interventions for controlling noise exposure among mine workers in the coalfield.
近年来,矿山噪声污染问题日益严重,引起了广大矿工的健康投诉。尽管人们越来越了解接触噪音与健康影响之间的关系,但只有少数研究调查了采矿业噪音污染对健康的不利影响。本研究旨在探讨采矿噪声(MN)、人口统计学特征(DC)、噪声敏感性和噪声烦恼(NA)与主观健康投诉(SHC)之间的相互关系。采用PLS-SEM方法对影响矿山272人SHC的因素之间的直接和间接关系进行了评价。使用声级计进行现场测量,以评估Jharia煤田Dhansar和Bastacolla矿区白天和夜间轮班期间1小时的环境噪声水平。噪音图显示,大部分地点的噪音水平高于70分贝(A)。统计模型表明NA是SHC最重要的预测因子。此外,DC和MN对SHC仅产生间接影响。这项研究将有助发展一套决策支援工具,以评估噪音水平、引起的烦恼、噪音强度,以及适当的政策干预措施,以控制煤田煤矿工人的噪音暴露。

Abstract Public spaces underwent a notable shift in their acoustic profile during the societal restrictions resulting from the COVID-19 pandemic. A silver lining emerged from this global crisis, with noticeable improvements in public acoustic environments due to reduced noise levels resulting from restricted mobility. This research focuses on the acoustic environment of Thessaloniki’s waterfront, a Mediterranean metropolis in Northern Greece. Waterfronts of Mediterranean coastal cities provide unique acoustic environments worthy of protection from environmental noise. By analyzing sound level measurements and recordings during the 2021 lockdown and comparing them to the post-lockdown period in 2022, we aimed to explore environmental noise and acoustic complexity indicators. The study’s findings revealed a significant increase in acoustic complexity during the lockdown, underscoring an inverse relationship between noise levels and acoustic complexity. Urban waterfronts, like Thessaloniki’s, hold great potential for enhancing acoustic complexity and subsequently improving the acoustic quality of public spaces while protecting them from environmental noise. This research sheds light on the possible use of sound complexity as an environmental quality standard that can be incorporated in sustainable urban planning and design.
在2019冠状病毒病大流行造成的社会限制期间,公共空间的声学特征发生了显著变化。这场全球危机中出现了一线希望,由于交通受限,噪音水平降低,公共声学环境得到了显著改善。这项研究的重点是塞萨洛尼基海滨的声学环境,这是希腊北部的地中海大都市。地中海沿岸城市的海滨提供了独特的声学环境,值得保护免受环境噪声的影响。通过分析2021年封城期间的声级测量和记录,并将其与2022年封城后进行比较,探索环境噪声和声学复杂性指标。研究结果显示,在封锁期间,声学复杂性显著增加,强调了噪音水平与声学复杂性之间的反比关系。像塞萨洛尼基这样的城市滨水区,在增强声学复杂性和随后改善公共空间的声学质量方面具有巨大的潜力,同时保护它们免受环境噪声的影响。这项研究揭示了声音复杂性作为环境质量标准的可能性,可以纳入可持续城市规划和设计。

Abstract Understanding the causes of noise annoyance requires recognition of the factors that affect soundscape perceptions. This study aims to explore multilevel factors of acoustic comfort and the perceived health effects of sound exposure, including personal traits, sound characteristics, and spatiotemporal features of the surrounding environment. We designed the Soundmap chatbot to collect data from the participants during May 16-July 16, 2022. The participants completed two tasks including sound recording and questionnaires. Sound feature extraction and identification were computed. Two soundscape perception variables were used as outcome variables and measured, and cumulative link mixed models were applied for statistical analysis. Results showed that for female participants, lower acoustic comfort was associated with sound exposure at night, at the land use of transportation and built-up areas, as well as the sounds of machines, vehicles, and airplanes. Low-frequency sound exposure and sounds of nature, silence, music, and human activity were associated with higher acoustic comfort, and these exposures were also associated with positive perceptions of health in rural areas and on weekends. Individuals with extraversion had a higher tolerance to sound; those with high noise sensitivity had a lower tolerance to sound. Understanding sound perception is crucial in maintaining a sustainable urban acoustic environment.
要理解噪声烦恼的原因,需要认识到影响声景感知的因素。本研究旨在探讨声舒适的多层次因素和声暴露对健康的感知影响,包括个人特征、声音特征和周围环境的时空特征。我们设计了Soundmap聊天机器人来收集参与者在2022年5月16日至7月16日期间的数据。参与者完成了录音和问卷调查两项任务。计算声音特征的提取和识别。以两个声景感知变量作为结果变量进行测量,采用累积链接混合模型进行统计分析。结果显示,对于女性参与者来说,较低的声舒适度与夜间、交通用地和建成区的声音暴露以及机器、车辆和飞机的声音有关。接触低频声音以及自然、寂静、音乐和人类活动的声音与较高的声学舒适度有关,这些接触也与农村地区和周末对健康的积极看法有关。外向性个体对声音的容忍度更高;那些对噪音敏感的人对声音的容忍度较低。理解声音感知对于维持可持续的城市声环境至关重要。

Abstract The development of citizen-based approaches to the diagnosis and decision-making on urban noise environments responds to a demand from both local authorities and residents. However, the methods for fostering the involvement of citizens and the valorization of local knowledge have yet to be invented. This article reports on a co-constructed experiment between researchers and local authorities, in the city of Rezé (France), of an urban noise diagnosis based on the residents and the use of the smartphone application NoiseCapture, which allows a participative measurement of sound levels. The framework also includes focus group discussions. The dynamics of the recruitment and data collection phase are analysed, showing the importance of creating public events around the initiative. Maps of noise levels, but also of the presence of sound sources, such as road, rail and air traffic, or animals, are produced in a collaborative way. Finally, the focus group discussions highlight that (i) repeated noise measurement modifies participants’ relationship to sound environments; (ii) NoiseCapture enhances the formation of a group of residents active on noise issues. Such a framework can provide a citizen-based basis for decisions on noise environments; the next step will be to study its adaptability to different territories.
摘要基于公民的城市噪声环境诊断和决策方法的发展响应了地方当局和居民的需求。然而,促进公民参与和提高当地知识价值的方法尚未发明。本文报道了研究人员和地方当局在雷泽市(法国)共同构建的一项实验,该实验基于居民和智能手机应用程序NoiseCapture的使用进行城市噪音诊断,该应用程序允许参与测量声级。该框架还包括重点小组讨论。分析了招聘和数据收集阶段的动态,显示了围绕该倡议创建公共活动的重要性。噪音水平的地图,以及声源的存在,如道路、铁路和空中交通,或动物,都是以协作的方式制作的。最后,焦点小组讨论强调:(i)重复的噪声测量改变了参与者与声音环境的关系;(ii)噪音捕捉促进了一群积极处理噪音问题的居民的形成。这样的框架可以为关于噪声环境的决策提供基于公民的基础;下一步将研究其对不同地区的适应性。
