Abstract The urban parks and gardens are usually surrounded by busy streets, commercial buildings and areas of high noise levels due to human activities and heavy traffic. These parks and gardens therefore have a unique function of providing relatively quiet areas to get away from the hustle and bustle of city lives. In this study, the sonic environment of the Singapore Botanic Gardens, which was the first UNESCO Heritage site in Singapore, was measured on various occasions and benchmarked with various urban gardens and parks around the world, namely the Luxembourg Gardens in Paris, Real Jardín Botánico in Madrid. St James’s Park in London, Old Botanical Gardens Hamburg, and Carlton Gardens in Melbourne. The Leq noise level was found to be compatible with the respective Leq noise level of the other urban parks and gardens. The sonic environment of the Singapore Botanic gardens was found to be dominated by cicada sound, human activities and water features. The sound level of various water features such as mini waterfalls and water fountains were also measured and analysed.

Abstract Deep learning (DL) methods have provided several breakthroughs in conventional data analysis techniques, especially with image and audio datasets. Rapid assessment and large-scale quantification of environmental attributes have been possible through such models. This study focuses on the creation of Artificial Neural Networks (ANN) and Recurrent Neural Networks (RNN) based models to classify sound sources from manually collected sound clips in local streets. A subset of an openly available AudioSet data is used to train and evaluate the model against the common sound classes present in the urban streets. The collection of audio data is done at random locations in the selected study area of 0.2 sq. km. The audio clips are further classified according to the extent of anthropogenic (mainly traffic), natural and human-based sounds present in particular locations. Rather than the manual tuning of model hyperparameters, the study utilizes Bayesian Optimization to obtain hyperparameter values of Neural Network models. The optimized models produce an overall accuracy of 89 percent and 60 percent on the evaluation set for three and fifteen-class model respectively. The model detections are mapped in the study area with the help of the Inverse Distance Weighted (IDW) spatial interpolation method.

Abstract This paper presents the results of a noise emission study of Autonomous Vehicles (AVs) and their impact on the road network. By comparing the current situation with a future hypothetical scenario (100% AVs penetration), this study highlights the positive effect, in terms of noise pollution, of the adoption of AVs on a real road network (city of Rome). For this scope, a traffic simulation-based approach was used to investigate the effects of AVs on the network congestion. Results show that the full AVs penetration scenario leads to an improvement in the network performances in terms of travel time and average network speed. Moreover, the amount of Vehicle Kilometre Travelled (VKT) shows an 8% increase on longer extra-urban routes, due to the higher capacity impact of AVs on highways, with a consequent load reduction for intra-urban shortcutting routes. These results are also reflected in terms of noise emission. In fact, the central area would benefit from lower noise emission, whereas an increase in traffic volume and speed lead to worsened conditions for some specific highway links of the network. Overall, it was shown that a 100% AVs fleet would have a beneficial effect for the noise pollution, leading to a general reduction of noise emissions, which is more pronounced for intra-urban roads.

Abstract In today’s era, vehicular noise pollution has been identified as a serious danger that influence the attribute of the urban regions. To identify the influence of noise effects, noise maps are very useful. A noise mapping study has been carried out to study the propagation of urban road traffic noise in the areas along with field measurements. The computer simulation model (Sound- PLAN software) is used to developed noise maps. In developing nations like India, traffic composition is heterogeneous. These traffic compositions contain vehicles, which have different sizes, speeds variations and operating systems. Because of fluctuating speeds, deficiency of lane disciplines, and non-authorized parking on main road lanes, honking events becomes inevitable, which changes and affects the urban soundscape of nations like India. Due to horn events (heterogeneous traffic condition), noise level (LAeq) increase by 0.5–8 dB (A) as compared to homogeneous traffic conditions.
在当今时代,车辆噪声污染已被确定为影响城市区域属性的严重危害。为了识别噪声的影响,噪声图非常有用。通过现场测量,对该地区城市道路交通噪声的传播进行了噪声制图研究。利用计算机仿真模型(Sound- PLAN软件)绘制噪声图。在印度这样的发展中国家,交通构成是多种多样的。这些交通组合包含不同尺寸、速度变化和操作系统的车辆。由于速度波动,车道规则的缺乏,以及在主要车道上未经授权的停车,鸣笛事件变得不可避免,这改变并影响了印度等国家的城市声景。由于喇叭事件(异质交通条件),噪声水平(LAeq)比均匀交通条件增加了0.5-8 dB (A)。

Abstract Since the 90s, quiet areas have commonly been considered as places to be acoustically preserved or where acoustic interventions should be implemented to reduce noise levels. With the enforcement of the Environmental Noise Directive in 2002, a formal definition of a ‘quiet area in agglomeration’ and a ‘quiet area in open country’ was established. However, many Member States complained about the absence of guidelines regarding the identification and management of quiet areas. The LIFE QUiet Areas Definition and Management in Action Plans (QUADMAP) project started in 2011 to contribute to the Directive’s incomplete requirements for quiet areas. The project’s main result has been the introduction of a flexible methodology for the selection, analysis and management of quiet areas in agglomeration in which both acoustic and nonacoustic parameters are evaluated. The current paper illustrates the analyses carried out on the data collected during the application of the selection, analysis and management phases of the developed methodology in the different pilot cases selected during the Project. Mentioned analysis are aimed at verifying the benefits of the proposed complementary selection criteria (‘relative quiet urban areas’ identification criteria and ‘homogeneous urban areas’ subdivision criteria), at defining the measurement periods most representative of the areas and the acoustic and nonacoustic parameters to be considered as the most significant.

Abstract We present soundwalk of Fushimi Inari Shrine in Kyoto, Japan from the main gate facing the Inari railway station to the summit. The soundwalk was captured from Samsung Galaxy S8 running NoiseExplorer: an app we have developed for Android and iOS. Fushimi Inari Shrine is the main shrine of the god Inari and sits at the base of a mountain also named Inari which is 233 meters above sea level. It also includes trails up the mountain to many smaller shrines which span 4 kilometers and takes approximately two hours to walk up. This shrine is ranked as the number one most popular sightseeing destination among tourists visiting Japan. A salient feature of the shrine is the rows of nearly 10,000 torii gates in striking orange color, which is known as the Senbon torii. The soundscape at the main gate and the main shrine was found to be dominated by the sound of cicadas. However, midway along the torii gates along the path towards the summit, cicada sound subsides, and the soundscape is more representative of typical footpath on mountain paths. The Leq noise level of 59.6 dBA is well below the typical noise level of other Japanese tourist attractions.

Abstract Noise mapping is a useful and widespread method to visualise various items like the exposure to noise pollution, statistics of affected population, different noise source contribution analysis, and it is also a useful tool in designing noise-control plans. Some researches have moved a step further, proposing maps to represent the people perception of the acoustic environment. Most of these maps use colours as mere tools to display the spatial variability of acoustic parameters. In this paper the colours associated by interviewed people to different urban soundscapes have been analysed, and the possibility of using meaningful colours to represent the soundscape quality in noise mapping has been examined. For this purpose, correspondence analysiswas applied on the data collected fromon-site interviews, performed in the water front of Naples and its surroundings. The outcomes show that in the pedestrian areas nearby the sea, the blue colour was often associated with the soundscape rating, whereas in the areas nearby the sea but open to road traffic the interviewees selected mainly the blue and grey colours. In the areas away from the sea, a wider selection of colours was observed: red and greywere predominantly selected in the areas open to road traffic and green, yellow and red in the green areas.

Abstract We report on the soundscape of Piazza Fontana di Trevi and Piazza Testaccio, gathering places in Rome. Soundscape is a realm of research about the interactions between cultural, cognitive and physical aspects of sound in space, still yielding interesting open questions.We performed perceptive surveys and instrument measurements, carefully spatialized in both cases. The perceptive results concern the recognizability of a particular sound in a conglomerate of sounds across an urban space and the sense of bodily orientation given by sound. They are proposed via verbal narratives and original visualizations of the place. We then use computer models to validate some of the perceived (unexpected) spatial perceptive features, by a ray-tracer simulation. The point of the paper is in fact to compare methods about sound in space, starting from perceptive evaluations, to drive objective analysis and collection of data toward new aspects, and always pursuing spatialization of data.

Abstract Environmental noise is increasing year after year, especially in urban and suburban areas. Besides annoyance, environmental noise also causes harmful health effects on people. The Environmental Noise Directive 2002/49/EC (END) is the main instrument of the European Union to identify and combat noise pollution, followed by the CNOSSOS-EU methodological framework. In compliance with the END legislation, the European Member States are required to publish noise maps and action plans every five years. The emergence of Wireless Acoustic Sensor Networks (WASNs) have changed the paradigm to address the END regulatory requirements, allowing the dynamic ubiquitous measurement of environmental noise pollution. Following the END, the LIFE DYNAMAP project aims to develop a WASN-based low-cost noise mapping system to monitor the acoustic impact of road infrastructures in real time. Those acoustic events unrelated to regular traffic noise should be removed from the equivalent noise level calculations to avoid biasing the noise map generation. This work describes the different approaches developed within the DYNAMAP project to implement an Anomalous Noise Event Detector on the low-cost sensors of the network, considering both synthetic and real-life acoustic data.Moreover, the paper reflects on several open challenges, discussing how to tackle them for the future deployment of WASN-based noise monitoring systems in real-life operating conditions.

Abstract The introduction of Low Emission Zones, urban areas subject to road traffic restrictions in order to ensure compliance with the air pollutants limit values set by the European Directive on ambient air quality (2008/50/EC), is a common and well-established action in the administrative government of cities. The impacts on air quality improvement are widely analysed, whereas the effects and benefits concerning the noise have not been addressed in a comprehensive manner. As a consequence, the definition, the criteria for the analysis and the management methods of a Noise Low Emission Zone are not clearly expressed and shared yet. The LIFE MONZA project (Methodologies fOr Noise low emission Zones introduction And management - LIFE15 ENV/IT/000586) addresses these issues. The first objective of the project, co-funded by the European Commission, is to introduce an easy-replicable method for the identification and the management of the Noise Low Emission Zone, an urban area subject to traffic restrictions, whose impacts and benefits regarding noise issues will be analyzed and tested in the pilot area of the city of Monza, located in Northern Italy. Background conditions, structure, objectives of the project and actions’ progress will be discussed in this article.
