实验室模拟与实地调查的声景评价对比研究

Comparative Study on the Soundscape Evaluation between Laboratory Simulation and Field Investigation

将实地照片与现场录音在实验室中进行重放,是实验室声景模拟研究的常用方法。本文运用该方法,对华侨大学校园声景观进行实验室模拟评价,将其结果与实地调研结果进行对比,探讨了实验室模拟声级对声景评价结果的影响,并在最佳模拟声级条件下分析实验室声景模拟评价与实地评价的异同,最后对实验室模拟方法在声景评价研究中的应用价值和不足之处进行了归纳总结,相关结论可以为声景观实验室模拟研究提供参考。

Audio-visual recording and playback technique in laboratory is a common way to simulate and study urban soundscape. With this method,this paper evaluated and simulated the soundscape of Huaqiao University in the laboratory,and compared the results with those of field studies. Then,the influence of the simulated sound pressure level on the soundscape assessment results was discussed, and the differences between simulated soundscape assessment and field studies under the optimal simulated sound pressure level were analyzed. Finally,this paper concluded the application values and deficiencies of the laboratory simulation method in soundscape assessment,providing references for the study of laboratory soundscape simulation.
