Abstract Today the so-called “smart city” is connoted by massive implementation of novel, digital technology, which is often considered as the best solution to global issues affecting contemporary cities. Sophisticated and low-cost technological solutions are developed also in the field of noise monitoring and they are expected to play an important role for acousticians, city planners and policy makers. However, the “smart city” paradigm is controversial: it relies on advanced technological solutions, yet it fails to consider the city as a social construct and it often overlooks the role of citizens, in the quest for technological advances and novel methods. This is especially true in the field of smart acoustic solutions addressing the issue of urban quiet areas: main methods and technologies developed so far barely involve citizens and consider their preferences. This contribution tackles this challenge, by illustrating a novel mixed methodology, which combines the soundscape approach, the citizen science paradigm and a novel mobile application - the Hush City app - with the ultimate goal of involving people in identifying, assessing and planning urban quiet areas. Firstly, the theoretical background and the methods applied are described; secondly initial findings are discussed; thirdly potential impact and future work are outlined.

Abstract Smart cities are required to engage with local communities by promoting a user-centred approach to deal with urban life issues and ultimately enhance people’s quality of life. Soundscape promotes a similar approach, based on individuals’ perception of acoustic environments. This paper aims to establish a model to implement soundscape maps for the monitoring and management of the acoustic environment and to demonstrate its feasibility. The final objective of the model is to generate visual maps related to perceptual attributes (e.g. ‘calm’, ‘pleasant’), starting from audio recordings of everyday acoustic environments. The proposed model relies on three main stages: (1) sound sources recognition and profiling, (2) prediction of the soundscape’s perceptual attributes and (3) implementation of soundscape maps. This research particularly explores the two latter phases, for which a set of sub-processes and methods is proposed and discussed. An accuracy analysiswas performed with satisfactory results: the prediction models of the second stage explained up to the 57.5% of the attributes’ variance; the cross-validation errors of the model were close to zero. These findings show that the proposed model is likely to produce representative maps of an individual’s sonic perception in a given environment.

The current European practice in noise policy the last fifteen years is primarily focused on the application of guidelines andmeasures related to noise reduction as described in the Environmental NoiseDirective (END) [1]. In the same wavelength, noise action plans and all the supportive documentation for strategic noise mapping [2] are focused mainly on improving the accuracy of the END and increase the precision of the reported population exposed at high noise bands. In this framework, mapping is a useful tool to aid the planning and design process [3]. Some studies have tried to formulate a better traffic model by using dynamic noise mapping techniques [4, 5] or even data extracted from participatory noise mapping techniques [6, 7]. Moreover, the need to combine a holistic approach in environmental noise policy by combining the noise mapping with the soundscape approach has recently been raised by the European Environmental Agency (EEA) in the Good Practice Guide on Quiet Areas [8].

Abstract Large scale noise exposure modelling is used in epidemiological research projects as well as for noise mapping and strategic action planning. Such calculations should always be accompanied by an assessment of uncertainty, on the one hand to check for systematic deviations and on the other hand to investigate the sources of uncertainty to address them in future studies. Within the SiRENE (Short and Long Term Effects of Transportation Noise Exposure) project, a large scale nationwide assessment of Switzerland’s road, railway, and aircraft noise exposure was conducted for the year 2011. In the present follow-up study, we equipped 180 sleeping and/or living room windows with sound level meters for one week. The resulting dataset was used to validate noise exposure modelling within SiRENE. For the noise metric LDEN the comparison revealed a difference of 1.6 ± 5 dB(A) when taking all measurements into account. After removing measurement sites with noise mitigation measures not considered in the modelling, the difference to the calculation was reduced to 0.5 ± 4 dB(A). As major sources of uncertainty, the position accuracy and topicality of infrastructure and building geometries, the traffic modelling as well as the acoustic source and propagation models were identified.

Abstract The Tranquillity Rating Prediction Tool (TRAPT) has been used to make predictions of the quality of tranquility in outdoor urban areas using two significant factors i.e. the average level of anthropogenic noise and the percentage of natural features in view. The method has a number of applications including producing tranquillity contours that can inform decisions regarding the impact of new anthropogenic noise sources or developments causing visual intrusion. The method was intended for use in mainly outdoor areas and yet was developed using responses from UK volunteers to video clips indoors. Because the volunteers for this study were all UK residents it was important to calibrate responses for other ethnic groups who may respond differently depending on cultural background. To address these issues further studies were performed in Hong Kong using the same video recording played back under the same conditions as the study in the UK. The HK study involved recruiting three groups i.e. residents from Hong Kong, Mainland China and a diverse group from 16 different nations. There was good agreement between all these groups with average tranquillity ratings for the different locations differing by less than one scale point in most cases.

Abstract The increasing human population and the increasing number of vehicles in Tirana, Albania, emerges the need for extensive measurements of noise levels. The 831 measurements of noise levels were taken in Tirana in November 2015 for education purposes. Measurements were collected in eight locations in indoor like a classroom in a school building environment, a library and a healthcare facility and in outdoor environments like five crossroads. Noise levels were then compared with domestic and World Health Organization (WHO) standards. The logarithmic average of noise levels and the maximum value of noise level measured for the period of measurement (LAFmax) were interpolated using Interpolated Noise Levels for Observer Points in ArcGIS producing noise level maps for crossroads. The logarithmic average of noise levels and LAFmax measurements were respectively above domestic and WHO standards in 96% and 100% of outdoor environment and indoor environment locations. Interpolated values of logarithmic average of noise levels and LAFmax for five crossroads were above domestic and WHO standards indicating noise levels in road traffic could remain high. A yearly acoustic measurement for vehicles should be implemented. Participatory measurements of noise levels in quite indoor environments can be used to increase the awareness of inhabitants in Tirana.

Abstract The assessment of soundscape implies an interdisciplinary approach, where objective and subjective aspects are considered. For the subjective evaluation, in situ and laboratory methodologies are usually followed. Local observations allow the collection of information on the influence of different stimuli present in the environment, whereas laboratory tests present a determined quantity of controlled stimuli to the evaluator. The purpose of this work is to compare results from the different methodologies in order to understand their strengths and their weaknesses. Three urban parks in the city of Lisbon, Portugal, were evaluated. Fragments of binaural sound recordings collected in the parks were used in laboratory tests to compare with the responses in situ and of expert and nonexpert listeners. Statistically significant differences were found in several of the perceptual attributes under observation, which led to variation in the results of the main model’s components. The sound environments were found to be more pleasant and uneventful in situ than in the laboratory, a phenomenon possibly due to the influence of other stimuli such as visual in the process of assessment. The in situ tests allow a systemic and holistic evaluation of the environment under study,whereas the laboratory tests allow a specific and tightly targeted analysis of different component sound events. Therefore, the two methodologies can be useful in soundscape assessment depending on the specific application and needs. No differences were found in the assessment made by either experts or nonexperts.

Abstract The impact of temporal aspects of noise data on model development and intra-urban variability on environmental noise levels are often ignored in the development of models used to predict its spatiotemporal variation within a city. Using a Land Use Regression approach, this study develops a framework which uses routine noise monitors to model the prevailing ambient noise, and to develop a noise variability map showing the variation within a city caused by land-use setting. The impact of data resolution on model development and the impact of meteorological variables on the noise level which are often ignored were also assessed. Six models were developed based on monthly, daily and hourly resolutions of both the noise and predictor data. Cross validation highlighted that only the hourly resolution model having 59%explanatory power of the observed data (adjusted R2) and a potential of explaining at least 0.47% variation of any independent dataset (cross validation R2), was a suitable candidate among all the developed models for explaining intraurban variability of noise. In the hourly model, regions with roads of high traffic volumes, with higher concentrations of heavy goods vehicles, and being close to activity centreswere found to have more impact on the prevailing ambient noise. Road lengthswere found to be the most influential predictors and identified as having an impact on the ambient noise monitors.

Abstract In the framework of the European Directive 2002/49/EC, from 2012 to 2016, several cities in Greece have completed noise strategic maps with noise action plans that usually define the main strategies to reduce the noise residents are exposed to and introduce and preserve “quiet zones”. Several medium urban agglomerations in Greece (Volos, Larissa, Chania, Heraklion, Corfu, Agrinio, Thessaloniki) have been chosen to also analyse the sound qualities of the soundscapes of specific urban neighbourhoods in order to generate recommendations for the urban design of the soundscapes of these agglomerations in a manner that complements conventional noise mitigation measures. The general principle of this approach is to relate quantitative data (e.g., from measurements, acoustic simulations, urban forms, topography, and traffic model) with qualitative data (e.g., from type of sources, interviews, reports on environmental noise perception) by creating quantitative and qualitative maps. The aim of this study is to propose possible action tools to the relevant authorities aiming at diminishing noise levels in affected areas and also to provide solutions towards a sustainable sound environment both in space and time. This paper presents the main current methodology, selected important results proposed for the urban agglomerations of a typical Southeast Mediterranean country such as Greece.

The acoustic quality assessment is a general problem that affects quite all cities, where human activities, such as industries, business and commercial centres, represent the heart of the urban context. The present research focuses on the use of an Index for the definition of the Acoustic Environmental Quality. The Acoustic Quality Index (AQI) was already described and used in previous researches. In this case, it is applied on a residential area characterised by moderate traffic noise and 4-6 floors buildings with a regular rectangular layout. The noise level data have been calculated by simulation and validated by experimental measurements. The results in terms of AQI have been compared with the ones obtained by a subjective investigation developed for this aim in the area. From the comparison, the need of a more suitable definition of the AQI has lead to the proposal for modifying the noise level ranges previously considered.

The results in terms of AQI have been compared with the ones obtained by a subjective investigation developed for this aim in the area. From the comparison, the need of a more suitable definition of the AQI has lead to the proposal for modifying the noise level ranges previously considered.","PeriodicalId":44086,"journal":{"name":"Noise Mapping","volume":"4 1","pages":"136 - 148"},"PeriodicalIF":2.8,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67160505","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
