“…Two components were found regarding soundscape perception; component 1 explained around 50% of the variance, while component 2 showed 20% of explained variance. Similar to the previous study (Kawai et al 2004;Berglund and Nilsson, 2006;Viollon and Lavandier, 2000;Axelsson et al, 2010;Rådsten-Ekman et al, 2013), component 1 was related to pleasantness including the adjectives pleasant, calm, chaotic, and annoying. Component 2 consisted of eventful, uneventful, exciting, and monotonous represented by the perception of eventfulness.…”

“…Pearson's correlation coefficients between the spatial function for a tranquil place and the acoustic elements in (a) the cathedral and (b) Buddhist temple precincts (*p < 0.05, **p < 0.01). (Axelsson et al, 2010;Rådsten-Ekman et al, 2013). In terms of audio-visual effect on tranquility, it was found that the effects of sound and visual environment on tranquility were similar even though the contribution of visual attractiveness was slightly larger than sound pleasantness in the cathedral precincts; the standardized multiple regression coefficients were 0.42 and 0.53, respectively.…”

Religious precincts in urban spaces have their own religious spatiality formed by their sociocultural and historical background. It is necessary to identify the spatiality of urban religious precincts in their sociocultural contexts because soundscape perception is determined largely by context. In the present study, social surveys and soundwalks were performed in a Catholic cathedral and in Buddhist temple precincts in Seoul. In the surveys, important spatial functions, sound, and visual components of the Catholic cathedral and Buddhist temple precincts were investigated by principal component analysis. The results showed that the cathedral precincts play a more important role in social functions related to mainly visual components than the temple precincts do, whereas the functions for religious activities related to sound elements are more stressed in the temple precincts. In the soundwalk evaluation, contributions of soundscape and landscape components to tranquility in the two religious precincts were explored. It was found that pleasantness of soundscape and attractiveness of landscape significantly affected the perception of tranquility. In addition, it was revealed that a sense of enclosure could enhance tranquility in urban religious precincts.

“…The adjectives have been identified as the characteristics of soundscape quality in previous studies, one of the most commonly used of which is pleasantness 13,14,45 . For the perceptual assessment of traffic noise, perceived annoyance is an important and frequently examined characteristic 1,4,46,47 .…”

“…Natural sounds, such as birdsong and water sounds, which may benefit people's relaxation in urbanised areas, 9 have been studied frequently, with particular considerations for their interaction with common urban noise, e.g., road traffic noise. 10,11,12,13 As a result, the concept of "masking" has re-emerged within the scope of soundscape because masking effects have been demonstrated to have considerable effects on the quality of soundscape. 6,14,15 Furthermore, due to the crucial role of human visual-aural interaction in sound environment However, in real-life soundscapes, the roles of sound source perception and cognition are highly relevant to masking effects.…”

* Corresponding authorThis study aims to explore how the soundscape quality of traffic noise environments can be improved by the masking effects of birdsong in terms of four soundscape characteristics, i.e., Perceived Loudness, Naturalness, Annoyance and Pleasantness. Four factors that may influence the masking effects of birdsong (i.e., distance of the receiver from a sound source, loudness of masker, occurrence frequencies of masker, and visibility of sound sources) were examined by listening tests. The results show that the masking effects are more significant in the road traffic noise environments with lower sound levels (e.g. <52.5 dBA), or of distance from traffic (e.g. >19 m). Adding birdsong can indeed increase the Naturalness and Pleasantness of the traffic noise environment at different distances of the receiver from a road. Naturalness, Annoyance and Pleasantness, but not Perceived Loudness, can be altered by increasing the birdsong loudness (i.e., from 37.5 to 52.5 dBA in this study). The Pleasantness of traffic noise environments increases significantly from 2.7 to 6.7, when the occurrence of birdsong over a period of 30 s is increased from 2 to 6 times. The visibility of the sound source also influences the masking effects, but its effect is not as significant as the effects of the three other factors.

“…Dubois [12] and Nilsson and Berglund [10] found a neutral impact of human sounds on the soundscape quality. For natural sounds, it seems that bird songs have a positive influence whatever the context but water sounds with temporal variability may have a positive influence whereas water sounds with high loudness and low temporal variability may have a negative influence on pleasantness [13][14][15][16]. In that frame, several researches studied the link between soundscape quality and relevant perceptual dimensions with regression models [17][18][19][20][21].…”

Noise Mapping

Abstract:The noise maps that are currently proposed as part of the EU Directive are based on the calculation of the Lday, Levening and Lnight. These levels are calculated from emission and propagation models that are expensive in time. These noise maps are criticized for being distant from the perception of city users. Thus, calculation models of sound quality have been proposed, for being closer to city users' perception. They are either based on perceptual variables, or on acoustic measurements, or on georeferenced data, the latter being often already integrated into the Geographic Information Systems of most French metropolises. Considering 89 Parisian situations, this article proposes to compare the sound quality really perceived, with those from models using geo-referenced data. It also looks at the modeling of perceptual variables that influence the sound quality, such as perceived loudness, the perceived time ratio of traffic, voices and birds. To do this, such geo-referenced data as road traffic, the presence of gardens, food shops, restaurants, bars, schools, markets, are transformed into core densities. Being quick and easy to calculate, these densities predict effectively sound quality in the urban public space. Visualization of urban soundscape maps are proposed in this paper.
