Abstract
Urban acoustic environment and sound implications on human health are increasingly receiving more attention in public and academia. Such as soundscape approach where the acoustic environment is analysed “as perceived by people in context” (ISO, 2017). Some implications of dominant sound sources, such as adverse impacts of traffic noise, are well known. However, there may be possibilities for empirical evidence on other sound sources. Therefore, this study aims to grasp to what extent urban acoustic environment could be evaluated by assessing the associations of dominant sound sources with perceptual attributes and sound pressure levels. To achieve this, data on sound sources, perceptual attributes and acoustic parameters were collected using Method A as defined in ISO 12913-2:2018 (ISO, 2018). The perceptual attributes separately and as the collapsed model of Pleasantness and Eventfulness were studied in correlative analysis. As a result, only weak relationships could be found. Findings add evidence to existing soundscape knowledge on the Pleasantness of natural, repulsiveness of traffic and Eventfulness of human dominant sound sources. It seems that different statistical variations of sound pressure measurements correspond to acoustic environments of certain sound dominance. The research provides with an empirical standing that the quality of urban acoustic environment could be explained by assessing the associations between dominant sound sources and perceived affective quality.
