Abstract
This study is part of a global collaboration to translate the soundscape attributes proposed in ISO/TS 12913-2:2018, which aims to standardise soundscape research globally. Cross-referencing results from two independent expert panels produced a set of eight soundscape attributes that were subsequently experimentally verified, forming a reliable questionnaire for soundscape characterisation in Mandarin Chinese. Employing the as-developed questionnaire, ex situ auditory-only soundscape perception experiments were carried out with 27 soundscape recordings from urban open spaces in the United Kingdom. The soundscape perception scale was used to evaluate participants' experiences, which were then projected into two dimensions of soundscape perception, pleasantness and eventfulness, following protocols from ISO 12913-3:2019. Physical and psychoacoustic parameters, as well as the characteristics of the sound sources, were extracted from the recordings. These parameters were used together to describe the soundscape characteristics of the recordings. Principal component analysis revealed that, when individuals are exposed to urban open spaces, the salient sound source becomes the foreground focus of attention, informing them to perceive the soundscape. Beyond this, perception stimulation is further based on the acoustic characteristics of the soundscape. Regression analysis investigated factors for pleasantness and eventfulness. For pleasantness, the overall S95 had a significant negative effect while birdsong was beneficial. With regard to eventfulness, mechanical sound had a detrimental impact, while the number of salient sound source types and the overall F50 had a positive impact. Furthermore, this study founds that certain types of sound sources make the sound more recognisable as a foreground sound, thereby stimulating perception, while others may be ignored as background sounds but still contribute to the perception through their acoustic characteristics.
