项目摘要

Surveys on community response to road traffic noise were carried out at sites with and without belt of trees in Tomakomai and at sites with and without noise barriers in Kyushu. The total numbers of respondents and response rates are 268,92.4% in Tomakomai, and 387,79.5% in Kyushu, respectively.The distributions of respondents regarding demographic parameters are almost the same. However, the significant reductions of general annoyance and activity interference were shown at sites with belt of trees and noise barriers. Particularly, the differences in general annoyance, annoyance caused by exhaust and difficulty to open windows were larger.Path analysis was applied to the social response and noise data to investigate what factors strongly affect general annoyance. The effects of exhaust and vibration on general annoyance were larger at both sites with and without belt of trees. At sites without trees, sensitivity to noise and quality of sleep affected annoyance more and at sites with trees, safety for road affected more. The effects of irritation and awakening were larger at both sites with and without noise barriers. At sites without noise barriers, sensitivity to noise and L_<eq> affect annoyance more and at sites with barriers TV/radio disturbance quality of sleep strongly affect annoyance.Such results suggest that safety for road and listening interference were relatively increased by visually concealing the noise sources with belt of trees and noise barriers and that not only reducing noise level but also the visual effect are important as noise measures.

在Tomakomai有和没有树木带的地点以及九州有和没有隔音屏障的地点进行了关于社区对道路交通噪音反应的调查。回答者总数和回答率分别为268，92.4%和387，79.5%。关于人口参数的回答者分布几乎相同。不过，在设有树木带及隔音屏障的地点，一般滋扰及对活动的干扰则显著减少。特别是一般烦恼、排气烦恼和开窗困难的差异较大。通过对社会反应和噪声数据进行通径分析，探讨哪些因素对一般烦恼有显著影响。排气和振动对一般烦恼的影响较大，在两个网站的树木带和不带。在无树木的地点，噪声敏感性和睡眠质量对烦恼的影响更大，在有树木的地点，对道路安全的影响更大。刺激和觉醒的影响较大，在两个网站有和没有隔音屏障。在无声屏障的场地，噪声敏感度和L_1<eq>对烦恼感的影响较大，而在有声屏障的场地，电视/收音机干扰对烦恼感的影响较大，这表明用林带和声屏障在视觉上隐蔽噪声源，可以相对提高道路安全性和听力干扰，降低噪声水平和视觉效果都是重要的噪声措施。
