Abstract
The perception of soundscape is complex and difficult to be described accurately. Although the use of physiological measurement in soundscape research is gradually increasing, most of them focused on proving the existence of the physiological effect, rather than construct the linear relationship between physiological indicators and soundscape perception. In this study, physiological indicators were used to classify sound source types, in order to provide physiological basis for sound source classification, and then the feasibility of using physiological indicators to evaluate soundscape quality was discussed. 20 scenarios of typical sound sources in urban public open spaces were presented in the form of audiovisual interaction in the laboratory, and 9 physiological indicators of 62 participants in these scenarios were measured. The dimensions of physiological indicators were reduced by categorical principal components analysis in order to study the distribution of different types of sound sources in physiological indicators. The results show that when using two dimensions to construct the physiological evaluation system, dimension 1 could well distinguish the difference between natural sound and human noise, however the meaning of dimension 2 was not clear, which means that the types of physiological indicators still need to be tested and adjusted, and also suggest that physiological indicators may be used to evaluate dimensions that are subjectively difficult to evaluate.
