摘要
以海口市为例,剖析了典型南方城市交通噪声的能量特征、时空分布、统计特性和居民主观反应.研究结果表明,该市道路车辆辐射噪声级较高,摩托车辐射声能占道路总声能的41%,东南区的污染大于西北区,Leq、L10、L50随时间变化呈现双峰双谷型,Leq平均值比L10低2.7dB(A),39.9%的居民对道路交通噪声感到高烦恼。
The energy and statistical characteristic,space-time distribution and people subjective reaction for the traffic noise from Haikou roads are analyzed in this paper. It revealed that the vehicle noise radiation was very high, the 41% of radiation noise energy came from motor, the noise pollution in southeast was larger than that in northwest, Leq,L10 and L50 of representative roads showed two peaks-two valleys type as the time goes, the average of Leq was 2.7dB（A） lower than L10, 39.9% of people felt great annoyance for it.
