Overall environmental assessment with soundscape and landscape indices in urban parks

초록

In this study, soundscape and landscape indices that can be used for overall environmentassessment of urban parks are proposed, and the effects of audiovisual interactions areexamined. In a virtual reality evaluation environment reproduced based on audio-visual datacollected from three parks in Paris, audio-visual element identification, perceived affective quality, and overall environmental assessment for a total of 30 subjects. Based on this, reference indices (Green soundscape index (GSI), Red soundscape index (RSI), Green landscape index (GLI), Red landscape index (RLI)) are defined based on the ratio of the audio-visual perception of nature and traffic or nature and people. In addition, Revised reference indices were proposed. Finally, environmental awareness models using structural equation model were presented. As a result, it was found that acoustic and visual satisfaction had 79 % and 21 % effect on overall environmental satisfaction, respectively. In addition, in order to increase acoustic and visual satisfaction, GLI should be increased and RLI should be decreased, and it was found that visual satisfaction can be improved when GSI is additionally increased.
