The Study And Evaluation Of Sound Scenes In Urban Park

At present,the research of landscape architecture is becoming more and more precise.As one of the important fields,the research of acoustic landscape has been rapidly developed in recent years.It plays an extremely important role in the overall landscape construction of urban parks.Based on the quantitative analysis and evaluation of the sound environment in the Sui and Tang Botanical Garden,this paper analyzes and discusses the correlation and overall sound level status of each sound landscape element by referring to literature,field investigation and questionnaire survey,etc.The landscape optimization strategy provides a reference for the optimization and upgrading of the acoustic environment in the Botanical Garden of the Sui and Tang dynasties.The main results of the study are as follows:(1)The sound landscape of the Sui and Tang Botanical Garden is composed of different sound sources such as natural sound,life sound and artificial sound,and there are certain differences in the time dimension.As the three most popular sounds,the whistling songbird cries,the best time to enjoy is 6:00-8:00.(2)The sound levels in areas with large pedestrian flow and high pavement hardening area,such as entrances to botanical gardens,square areas,and leisure areas,are large;the sound levels in dense forest areas and water scenic areas with low flow and high vegetation coverage are small.The holiday sound level is relatively high.(3)In terms of sound scene saliency,preference,and coordination,the sound elements with higher sound scene elements are life sounds and the lower ones are artificial sounds,both of which are greatly affected by the time dimension and space dimension,The higher coordination is natural sound and life sound.(4)Correlation analysis of soundscape elements shows that preference and coordination are extremely significantly correlated.In the subjective feeling evaluation of soundscape,the five main common factors of lightness,satisfaction,coordination,uniform comfort,intimacy and ease are summarized as the influencing factors of the soundscape of the Sui and Tang Botanical Garden(5)The sound environment of the Sui and Tang Botanical Garden has the problems of high sound level in the entrance area,square area,etc.,and the sound level in dense forest areas,water scenic areas and other places with high vegetation coverage is small,and there is a lack of sound scene related identification system in the park(6)The optimization strategy is to focus on the overall noise reduction of the entrance area,square area,and leisure area,expand the scale of the dense forest area and water scenic area,introduce water sounds,animal sounds,and increase the sound scene identification system.
