- W2359879875 abstract "Objective:To investigate the relationship among status of traffic noise pollution,regional distribution,and vehicle flow in Haikou,and the effect on residents,and to explore the controlling measure.Methods:Four main traffic roads were selected as monitoring sites.Noise grade were measured during the three peak periods and one low peak period in a day,and the vehicle flow was monitored by hour.All data were analyzed by spss12.0.Results:The average noise grade in day(Ld) was(70.72±4.37) dB,with significant regional difference.The Ld was the highest in Haifu Rd,followed by Xiuying Rd,Yanjiang Rd and Yingbin Rd.It was much higher in night[(67.39±3.84) dB].8.6% correspondences regarded the noise as very unbearable,23.4% as annoying,56.2% as little annoying and 11.8% as no annoying.Noise levels were positive related to vehicle flow without linear relation.Logistic analysis indicated that sex,noise source,noise grade and health condition are relevant factors.Conclusions:Traffic noise is significantly higher than the standard level with significant regional difference.The noise grade is also associated with vehicle flow.Besides,the impact of noise is also related with greening status,road condition,sound arrester and so on.It is necessary to manage and control noise in the roads." @default.
