1989年成都市城西区域环境噪声质量评价

《1989年成都市城西区域环境噪声质量评价》按G B32222—82规定进行。布点方法为500M×500M网格布点,共布点108个。测试仪器采用符合国家计量标准的先进、可靠的HY104声级计。测量时间为8:00～12:00、14:00～20:30。测量时准,确地摸清了城西区域环境噪声的声源状况——生活声源59.2%,交通声源29.9%,施工声源7.5%,工业声源3.4%——并通过评价分析确定了影响该区域环境噪声声学质量的主要声源为交通声源。所得大量数据经处理、分析后得出该区域环境噪声声学质量为轻度污染级至良好级之间的正确结论。本文还就噪声污染的防治提出了一系列切实可行的措施。

Environmental Noise Quality Assessment In West District,Chengdu,1989

Environmental Noise Quality Assessment In West District, Chengdn, 1989was conducted according to the of the GB3222-82, It adopted the 500m×500mnetwork measurement The total nurnber of the sports weve 108. The measurement instrument, TYPE HY 104 sound-level meter, conformedto the advanced, veliable national measurement standards. The measuring dur-ation was 8:00～12:00, 14:00～20:30.Based on the measurement, the condit-ion of environmental noise in west distirict were accuvatcly masteved(domesticnoise souvce 59.2%, tvaffic noise source 29.9%, construction noise source 7.5%industry noise source 3.4%), And the trffic noise is determined as the majorsource which effects the acoustics quality of environmental noise through asse-ssment and analysis. After tveating and analysing the obtained large data, the correct conelu-sion which acoustics quality of the onvironmental noise in this district is lightpollution to sound level has been got. This article also suggests a series of feasible measuves of noise pollutioncontrol.
