“…To minimize impact on the participants' life, we designed our interviews to last no longer than a successful marketing or fundraising interaction, i.e., 15-min (Market Research Society, 2014). Advantageously, 15-min should also be sufficient to establish a perceptual acoustic judgement, according to recent models of acoustic perception (De Coensel and Botteldooren, 2008) and to some experimental studies on planes (Breugelmans et al et al, 2017) and other traffic sources (Memoli et al, 2008; Memoli and Licitra, 2012).…”

It is accepted knowledge that, for a given equivalent sound pressure level, sounds produced by planes are worse received from local communities than other sources related to transportation. Very little is known on the reasons for this special status, including any interactions that non-acoustical factors may have in listener assessments. Here we focus on one of such factors, the multisensory aspect of aircraft events. We propose a method to assess the visual impact of perceived aircraft height and size, beyond the objective increase in sound pressure level for a plane flying lower than another. We utilize a soundscape approach, based on acoustical indicators (dBs, LA, max, background sound pressure level) and social surveys: a combination of postal questionnaires (related to long-term exposure) and field interviews (related to the contextual perception), complementing well-established questions with others designed to capture new multisensory relationships. For the first time, we report how the perceived visual height of airplanes can be established using a combination of visual size, airplane size, reading distance, and airplane distance. Visual and acoustic assessments are complemented and contextualized by additional questions probing the subjective, objective, and descriptive assessments made by observers as well as how changes in airplane height over time may have influenced these perceptions. The flexibility of the proposed method allows a comparison of how participant reporting can vary across live viewing and memory recall conditions, allowing an examination of listeners' acoustic memory and expectations. The compresence of different assessment methods allows a comparison between the “objective” and the “perceptual” sphere and helps underscore the multisensory nature of observers' perceptual and emotive evaluations. In this study, we discuss pro and cons of our method, as assessed during a community survey conducted in the summer 2017 around Gatwick airport, and compare the different assessments of the community perception.

“…2.2). Other approaches rely on simulating the auditory stimuli response on individuals by moving the role covered by sound source presence into event saliency recognition [33,34,35,36,37,38], and by maintaining the cognitive and emotional factors on a higher level [32]. However, sound sources and event saliency recognition can still be considered as good indicators to fit the model.…”

A systematic review of prediction models for the experience of urban soundscapes

A systematic review for soundscape modelling methods is presented. The methods for developing soundscape models are hereby questioned by investigating the following aspects: data acquisition methods, indicators used as predictors of descriptors in the models, descriptors targeted as output of the models, linear rather than non-linear model fitting, and overall performances. The inclusion criteria for the reviewed studies were: models dealing with soundscape dimensions aligned with the definitions provided in the ISO 12913 series; models based on soundscape data sampled at least at two different locations and using at least two variables as indicators. The Scopus database was queried. Biases on papers selection were considered and those related to the methods are discussed in the current study. Out of 256 results from Scopus, 22 studies were selected. Two studies were included from the references among the results. The data extraction from the 24 studies includes: data collection methods, input and output for the models, and model performance. Three main data collection methods were found. Several studies focus on the different combination of indicators among physical measurements, perceptual evaluations, temporal dynamics, demographic and psychological information, context information and visual amenity. The descriptors considered across the studies include: acoustic comfort, valence, arousal, calmness, chaoticness, sound quality, tranquillity, and vibrancy. The interpretation of the results is limited by the large variety of methods, and the large number of parameters in spite of a limited amount of studies obtained from the query. However, perceptual indicators, visual and contextual indicators, as well as time dynamic embedding, overall provide a better prediction of soundscape. Finally, although the compared performance between linear and non-linear methods does not show remarkable differences, non-linear methods might still represent a more suitable choice in models where complex structure of indicators are used.

“…Using the data obtained from a large-scale survey, a model based on artificial neural networks has been developed to predict soundscape perception (Yu and Kang 2009). More fundamentally, a bottom-up approach is also needed, considering the individual sensory, cognitive and emotional mechanisms (De Coensel and Botteldooren 2008;Niessen et al 2009). Modelling physics side, namely sound propagation is a space is also relevant here, where a number of models have been developed (Kang 2005;Attenborough et al 2006).…”

Soundscape in city and built environment: current developments and design potentials

In the field of environmental acoustics, the conventional approach of reducing ‘sound level’ does not always deliver the required improvements in quality of life. Soundscape, defined by the ISO as the ‘acoustic environment as perceived or experienced and/or understood by a person or people, in context’, promotes a holistic approach, regarding sounds as ‘resources’ rather than just ‘wastes’. The first part of this review/position paper, mainly using the works by the author and the teams/collaborators as examples, discusses the current developments in soundscape, in terms of soundscape understating and exchanging, collecting and documenting, harmonising and standardising, creating and designing, and outreaching, showing that while considerable works have been carried out, much work is still needed, in terms of basic research, and more importantly, research towards practice. The second part of this paper then explores a soundscape approach in the urban sound design/planning process. With a proposed framework for designing soundscape in urban open public spaces, considering four key components, including characteristics of each sound source, acoustic effects of the space, social/demographic aspect of the users, and other physical conditions, design potentials are demonstrated.
