A Study Of Watersound Influencing Subjective Evaluation Of Soundscapein Commercial Pedestrian Street

Commercial pedestrian street construction as part of the construction of urban public space, the reasonable environment for residents’ daily life rich, show the local features is important. Construction of the space environment and the research should be omnidirectional multiple points of view, however, in the construction of the current business environment, often only in visual space construction and economics as the guidance, and for sound and sound quality build scene attention to spend less, and achieve the optimization of sound environment quality of the relative lack of means. Many environmental design practice shows that w ater often as an important element of outdoor space comfort pleasure, acoustic and has a good sound effect.As a result, this article choose sound commercial pedestrian street landscape as the main research object, through the review status of commercial p edestrian street, commercial pedestrian street of existing situation, construction requirements, general classification, space scale, etc., clear sound commercial pedestrian street landscape concept and influencing factors. And reference for the related so und scene study practice, laboratory simulation method is chosen as the research method, this paper USES semantic differential and sorting method to establish evaluation system. Again after, through the analysis and evaluation of all kinds of sound, objective description water, of water for people and cognitive subjective evaluation.Based on the above content, analysis of commercial pedestrian street scene and the possible relationship between acoustic, from objective and subjective psychological amount on the two angles to consider acoustic subjective evaluation of the impact of commercial pedestrian street based on improve the quality of sound commercial pedestrian street landscape, and select the appropriate acoustic overlay with sound commercial pedestrian street scene, again for laboratory subjective evaluation, the experimental results and the existing sound commercial pedestrian street landscape evaluation results, analysis of commercial pedestrian street underwater scene the actual impact of subjective evaluation.
