An objective evaluation method for the road traffic noise impact on soundscape - West Lake as a case

摘要

A positively judged soundscape generally includes both natural and social/cultural sounds in the sonic environment such as birds singing, water flowing, bell ringing, music playing, etc. Road traffic noise is a major source that may interrupt and even impact the natural and social/cultural soundscape. Many of the studies consider a soundscape, which includes road traffic noise, natural and social/cultural contexts were based on an objective, social scientific assessment, mainly using an on-site questionnaire, to develop an understanding of the situation. This paper tries to develop the correlation between road traffic background noise and environmental or community sound, proposing an objective evaluation method for protecting the soundscape from road traffic noise. It is hoped this method would not only overcome the shortcomings of subjective investigation, but also would provide a warning of impending damage and could be applied to early alert the interrupt, impact, and destruction to soundscape by road traffic noise.
