摘要
叙述了隔声技术在民用工程噪声控制中的几种应用 ,特别对固定式和活动式声屏障的设计方法、使用效果作了介绍。声屏障用于降低以空气动力性噪声为主的水泵、风机、冷却塔等噪声源 ,结合室内吸声处理能收到明显的效果。
This paper desceribes the applications of the sound insulation technology to noise control in civil engineerings.It especially introduces its design methods and effects for the fixed and movable barriers.The barriers,which can reduce the noise sources of a pump,a fan and a coolling tower,have an evident effect with the indoor absorbing treatment.
