Research On The Investigation Of Soundscape In Shenyang Beiling Park

Sound landscape is an important part of the park landscape environment.The optimization of sound landscape is helpful to improve the overall comfort evaluation of the park.Beiling Park is a comprehensive park with complete functions integrating cultural,entertainment and scenic spots.It has a wide range of users and is a landmark window for Shenyang to the world.However,with the increase of the number of users,many users reported that the quiet environment began to be noisy,which affected the experience of leisure and recreation.The survey also found that the cultural tourist attractions lacked the integration of historical and cultural sound,and the noise that did not conform to the atmosphere such as broadcast sound seriously affected the experience of tourists.Therefore,the field investigation of Beiling Park,the objective analysis of its sound landscape status and user perception and evaluation,and the discovery of practical problems are of great practical significance to optimize the sound landscape environment of the park,as well as reference value to the construction of sound landscape of cultural tourism park.This paper takes Beiling Park in Shenyang as the research object.From July to November,2018,the sound diffuse method is used to summarize the sound landscape composition,sound source types and sound source cognitive preferences of the park.The sound level of the park is measured by ws1361 sound level meter,and the overall characteristics of the time distribution,spatial distribution and sound level size of the sound landscape in the park are analyzed.In addition,a questionnaire was sent out to analyze the perception difference,environmental cognition preference,quietness and audio-visual environment comfort of tourists.Using the inverse distance weight interpolation method to form the soundscape comfort map,intuitively display the research results of analysis and evaluation of soundscape,and lay a theoretical foundation for in-depth study of soundscape design in the park.Finally,through the data analysis method,it summarizes the improvement suggestions of the sound scene of cultural tourism park and the construction means of historical sound.The analysis shows that the sound landscape of Beiling Park is composed of natural sound,life sound and artificial sound.The characteristics of sound landscape in different locations are related to their location conditions and functional positioning.There is a strong interaction between the park's hearing comfort,visual comfort and the overall environmental comfort.The activity sound of people in Beiling Park dominates the diversity index of sound environment.The effective measures to improve the sound landscape of the park are to increase people's preference for natural sound,such as bird call,wind sound,wind blowing leaves sound,etc.,and to reduce the living sound and artificial sound.The square needs to limit and control the type and time of activities.The natural landscape node needs to pay attention to the impact of the auditory environment and activity content.In the activity space with characteristics,the visual landscape design should be more cultural,and the interaction between tourists and the landscape should be increased.In conclusion,the sound landscape of the park can be improved by optimizing the artificial noise,strengthening the construction of natural sound,increasing the interactive landscape,and setting the bionic device.Finally,combined with the browsing of historical data,the sound elements that retain the cultural and historical charm can be screened out and applied to the cultural tourism park,and suggestions for its planning are put forward: optimize the original historical relics resources;arrange the calendar included Historical elements of the soundscape skit;the use of high-tech methods;the establishment of a historical podium;add cultural and folk arts and crafts entertainment.
