Analysis And Optimization Design Of Acoustic Landscape Chanacteristies Of Baotu Spring Park,Jinan

As an important part of the city,city park is an important place for people daily recreation activities,people experience involving the five senses,in urban park planning and design,however,people focus on visual landscape construction,often ignores the function of acoustic landscape,etc,thus to explore the city park landscape characteristics,put forward the optimization strategy of acoustic landscape of city park,can promote the construction and development of acoustic landscape park,and provide reference for other topics sound city park landscape research.This paper takes the characteristics of the sound landscape of baotu spring park as the main research object,and analyzes the characteristics of the sound landscape of urban parks by means of literature research,sound landscape walking,sound field measurement,questionnaire survey,statistical analysis and sound quality simulation.From the sound source,to understand the elements of the sound landscape;Investigate and analyze the subjective and objective evaluation of park acoustic environment,establish reasonable evaluation indexes for urban parks,and analyze the characteristics of acoustic landscape;The quadrangle courtyard and theater building,which are the most common garden buildings in urban parks,were selected for further analysis to understand their influence on the sound and landscape of the park.Through investigation and analysis,this paper mainly draws the following conclusions: the preference of natural sound in the sound source is high,the preference of spring water is the highest,and it can mask the noise to a certain extent,and improve the satisfaction of sound environment;Mechanical sound preference degree is low,should try to avoid;The existence of underwater sound can significantly improve the satisfaction of acoustic environment.In this study,the educational level of acoustic environmental satisfaction was largely affected by gender,age and region.The larger the courtyard in the courtyard space,the shorter the reverberation time and the lower the degree of noise increase;Proper underwater acoustic design can improve the satisfaction of acoustic environment to some extent.When the stage building has aperformance,the acoustic environment has a large influence range,which greatly reduces the quietness of the acoustic environment,thus reducing the satisfaction of the acoustic environment in the peripheral areas where the performance cannot be seen.According to the above characteristics of sound landscape further put forward the optimization design of the sound landscape design of the park: the park and the city road junction should set up a certain noise reduction landscape;The negative sound source can be masked by the sound of running water where the noise is obvious in the park.The setting of stage area wall can not only reduce the noise to the external interference,but also enhance the internal sound;Appropriately add feature sound source.Various sound sources in baotu spring city park record the way of life in which the urban tradition and modern blend,so its sound landscape is of great research value.This study can better promote the development of spring theme park,and provide reference for other theme parks' acoustic landscape research,and provide theoretical reference for similar urban park design in the future,so as to improve the quality of urban park's acoustic environment.
