Research On The Investigation Of Soundscape In Shenyang Urban Park

The improvement of the modern living standard brings us convenience as well as various pollutions.Noise pollution is one of them,especially traffic noise,industrial noise,etc.,which seriously affect people's normal life.At the same time,with the development of tourism,urban parks have gradually become the center of urban tourism.The pleasant environment of the city park and convenient transportation have been welcomed by the general public.The city parks are mostly located in the city center and have been affected by noise pollution for a long time.However,for a long time,the landscape design of urban parks often only stays at the level of visual elements,ignoring the influence of other sensory elements such as hearing and smell on people's subjective perception.This paper firstly consults relevant literature and books,learns the relevant knowledge of acoustic landscape,summarizes the research methods and research results of acoustic landscape at home and abroad,and on this basis,the typical urban park built in Shenyang City,Shenyang Zhongshan Park,Shenyang Wan Field surveys and questionnaire surveys were conducted on the acoustic landscapes of Quan Park and Shenyang Nanhu Park.The sound level measurements of the three parks were performed by the WS1361 sound level meter from July to October 2018,and the acoustic landscape composition,sound source types,and The overall characteristics of sound size,time and space distribution.The questionnaire uses the Likert scale method(five-point method)to collect the subjective evaluation of the park's acoustic landscape;using SPSS software to analyze the correlation between subjective loudness and goodwill,subjective loudness and sound level;and try to introduce new The concept of noise pollution sub-index and green soundscape index to evaluate the park.research shows:(1)The acoustic landscape of Shenyang City Park is mainly composed of three types of soundscapes: natural sound,living sound and artificial sound.The proportion of each type of soundscape is related to the surrounding environment of the park and the behavior of tourists,and the sound size and time distribution of the park.The spatial distribution was analyzed.The sound level,noisyness,quietness and pollution index were used to objectively evaluate the park's acoustic landscape.(2)This paper adopts several important indicators of acoustic landscape evaluation: subjective sound loudness,goodwill,satisfaction and green soundscape index to subjective evaluation of park sound landscape,analyze different tourists' perception of sound landscape,and like tourists Sort with sound elements that you don't like.Through the correlation analysis between good sensitivity and subjective loudness,the correlation between goodness and subjective loudness is weak,and the user's goodwill to the sound landscape is not directly affected by loudness.Other factors such as weather conditions and tourists Mood,personal preference,etc.all have an impact on the evaluation results.Listeners of different genders,ages,academic backgrounds,and professional backgrounds have different levels of perception of the sound landscape.(3)There are some shortcomings in the acoustic landscape of Shenyang City Park: for example,the characteristics of the acoustic landscape are not obvious,and the sound landscape is not applied to the actual planning and design;the artificial sound,the living sound and the natural sound are not balanced,the artificial sound and the living sound Excessive weight;lack of noise reduction at the periphery of the park;lack of classical sound landscape elements and design management of the soundscape landscape.
