Abstract:
With the improvement of people's awareness of environmental protection and the rise of soundscape-related research in China, the impact of soundscape on urban green space is deepening. Based on the objective sound pressure level and subjective sound comfort evaluation data of the greenway acoustic environment performance, by analyzing the factors influencing the soundscape quality of the site, the optimization strategy and suggestions for the soundscape of the first phase of Jincheng Greenway are proposed from a multi-dimensional perspective. The main results and conclusions are as follows: first, the traffic noise generated by urban roads has a significant impact on the greenway, and the landscape nodes within the greenway present a point-like aggregation of high sound pressure level. Second, tourists have high expectations for quiet acoustic environment, and quiet areas with high natural sound are more likely to be accepted by tourists. At the same time, the disturbance degree of negative sound and the coordination of site functions are the main factors that produce differences in acoustic environment. Finally, a coordinated acoustic environment can be formed only through overall planning and multi-process control in sound sources, transmission processes and the sound receiving places.
