中文摘要:
      文章分析了大型水泥浇注的老式机械通风冷却塔噪声产生的机理,针对现场噪声源与居民区分布的实际情况,提出了一种用消声、隔声、吸声等多项技术进行综合治理的措施,使声源噪声有较大的降低,并且充分利用声波距离衰减原理,使居民区环境噪声达到了国家环境噪声标准的要求,取得了较好的环境效益和社会效益。
英文摘要:
      The principles of the generation process of noise from the large cement old moded mechanical ventilating cooling tower are analyzed in the paper.Based on noise and distribution about dwellings on the spot,the general noise control technique such as noise elimination.Sound insulation sound absorption are used to make great use of the principle of sound decay.The noise has been reduced a lot Environment noise around dwellings meets the national standards of environment noise control.Thus environmental and social benefits are obtained.
