친환경 사운드스케이프 조성을 위한 도시 환경음의 쾌적성 평가

The assessment of an urban site depends on the way it responds to multiple needs such as functionality, aesthetic and complex comfort of acoustic, thermal, lighting and air quality This study aims to investigate the assessment of various urban soundscapes in the sense of acoustic amenity by the questionnaires. As a result, acoustic amenity assessment was influenced by the non-acoustic factors such as environment assessment of visual, thermal, air quality etc.. And it was shown that the subjects tend to perceive the noise level less than 3$\sim$10dB L$_{Aeq}$ under the similar noise exposure level according to the urban landscapes.
