环境振动主观评价规律初探

An Investigation on Community Response to Environmental Vibration.

依据在我同五个城市进行的环境振动对居民影响的调查结果,本文分析了居民对环境振动的主观评价规律,表明烦恼率随振级的增高而升高,烦恼率随振级变化的整体趋势呈现出S形状。用u检验法、心理物理学原则及S曲线拐点法计算出居民烦恼阈限振级在70—76dB范围。本文的结果为制定我国城市区域环境振动标准提供了基本依据。

Based on the investigations into environmental vibration caused by industrial machines in five cities in China, the paper analyzes the community responses in terms of subjective evaluation. The annoyance percentage increases with the Z-weighted vibration level and tendency behaves in the shape of S. The annoyance thresholds calculated by the u-test, the principle of psychological physics and turning point of the S-shaped curve are in the range from 70 to 76 dB(Z-weighted vibration level). The results have provided the national standard 'GB10070-88 Standard of Environmental Vibration in Urban Area' on this basis.
