公园环境噪声的主观反应及烦恼度阈值

本文用模糊数学处理游客对公园环境噪声主观反应的所有信息,给出各中心声级下的烦恼概率,并以此加权平均,得出公园不同区域环境噪声烦恼度的阈值;草坪休息区等效声级63.3dBA,游览观赏区63.6dBA,茶室餐饮区70.9dBA.本文所采用的方法比心理物理法计算得出烦恼度阈值更为理想。

Subjective response to environmental noise in park and annoying threshold

In this paper,we get the probability of annoyance under each central sound level, dealing with all the information of subjective responses to the environmental noise in the park by principle of fuzzy mathematics. Also we get the annoying threshold of the environmental noise in different districts of the park:63. 3dBA in grassy area, 63.6dBA in enjoyable area and is 70. 9dBA tea room and restaurant. The method of getting annoying threshold in this paper is more reasonable than the method of psychical and physical calculation.
