摘要
针对HJ 2.4—2009《环境影响评价技术导则声环境》中面声源的几何发散衰减计算存在的问题,提出采用工程法计算a×b面声源噪声几何发散衰减方法,并通过实例分析进行比较论证。
To aim at the current problems of the attenuation computation of geometrical spreading for area noise source in'Technology Guidelines of Environment Impact Evaluation——Acoustic Environment'( HJ 2. 4—2009),the engineering method was used to calculate attenuation law of geometrical spreading of the area noise source( a × b),which was comparatively demonstrated through the instance.
