冬季不同植物空间类型对城市公园声环境的影响研究
Research on the influence of different plant space types on the acoustic environment of urban parks
摘要
Abstract
To explore the influence of different types of plant spaces on the acoustic environment and noise reduction,taking Jindou Park in Hefei City as an example,acoustic environment parameters and citizens' subjective acoustic perception were obtained through on-site measurement,questionnaire survey and software simulation.The acoustic preferences and acoustic environment parameters in urban parks were analyzed and simulated using Origin and Cadna/A software.The results show that citizens' prefer-ences for sound sources vary significantly.In winter,citizens prefer musical sounds,natural sounds and artificial sounds.The simulation shows that while vegetation can reduce noise,its effect is limited.In contrast,the implementation of traffic road optimization measures yields a more significant noise reduction effect,with a maximum reduction of 4.5 dB.Different types of plant spaces in winter have a significant impact on the acoustic environment and the level of noise reduction.The order of noise reduction intensity from high to low for each spatial type is:open space,semi-open space,closed space,covered space.The original plant community in the covered space is relatively rich,resulting in a noise reduction of only 1.8 dB in the model optimization.There is a negative correlation between the sound pressure of different spatial types in urban parks and the distance from traffic roads.When the distance between the monitoring point and the traffic road is 0 m,the average sound pressure value is 71.0 dB.When the dis-tance increases to 200 m,the sound pressure value significantly decreases to 48.0 dB.关键词
