摘　　要：针对步行街临干道布置、噪声污染严重的情况,通过声漫步法获取声环境感知调查问卷,通过语义分割软件获取空间可视性指标,结合声环境感知和空间可视性指标来探究临干道步行街声环境感知与空间可视性的关系。研究发现,实测地点声环境感知产生明显聚类,分为空间开敞类和围合类两大类;聚类与空间可视性指标密切相关,空间开敞类对于因空间可视性指标变化而引起的声感知的变化比围合类更为敏感;随着临干道步行街由开敞类转为围合类,且功能业态由复杂转为简单,声舒适度和协调度逐渐升高,响度逐渐降低。该研究可为临干道步行街的设计优化提供理论支持。Pedestrian streets are arranged adjacent to traffic arterial roads,causing serious noise pollution.This study first obtains the acoustic environment questionnaire through the acoustic walk method,then obtains the spatial visibility index through the semantic segmentation software,and finally combines the two to explore the relationship between the acoustic environment perception and the spatial visibility of the pedestrian street near the main road.The study found that there are obvious clusters in the acoustic environment perception of the measured locations,which can be divided into two categories:open space and enclosure;the above clustering is closely related to the indicators of spatial visibility,and the spatial openness is important for spatial visibility.Changes in acoustic perception caused by changes in indicators are more sensitive than enclosed types;at the same time,it is found that as traffic arterial pedestrian streets change from open type to enclosed type,and the functional format changes from complex to simple,acoustic comfort and coordination The loudness gradually increases,and the loudness gradually decreases.The research can provide theoretical support for the design optimization of the pedestrian street adjacent to the main road.
