【摘要】：采用里克特5级量表(1:非常不舒适;5:非常舒适)实验研究了不同声级的道路交通声评价在生态水体景观视觉影响下的规律。分析发现:与单听觉测试条件相比,生态水体景观将道路交通声级与声评价的相关系数由-0.91降低至-0.81~-0.57,其中30 dBA的道路交通声评价值下降0.13~0.68,而70 dBA的道路交通声评价值升高0.10~0.22。在一定声级范围内景观要素对道路交通声评价的影响不同:人工要素比自然要素影响下的道路交通声评价值高0.33/10 dBA;自然水体远景比近景影响下的道路交通声评价值高0.33/10 dBA;人的活动要素比动物活动要素影响下的道路交通声评价值高0.28/10 dBA,
[Abstract]:Using the Richter scale of 5: very uncomfortable; 5: very comfortable) experiments were conducted to study the rules of road traffic sound evaluation under the visual influence of ecological water landscape. Ecological water landscape reduced the correlation coefficient between road traffic sound level and sound evaluation from -0.91 to -0.81 to -0.57. The road traffic sound evaluation value of 30 dBA decreased by 0.13 ~ 0.68. However, the evaluation value of road traffic sound of 70 dBA increased by 0.10 ~ 0.22. The influence of landscape elements on the evaluation of road traffic sound was different in a certain range of sound levels. The value of artificial factors was 0.33 / 10dBA higher than that of road traffic acoustics under the influence of natural factors. The potential value of natural water body is 0.33 / 10 dBA higher than that of road traffic acoustical evaluation under the influence of close-range. The activity factors of human beings were 0.28 / 10 dBAs higher than that of road traffic acoustics under the influence of animal activity factors.
