摘要
噪声污染、空气污染和水污染并列为当今环境的三大污染。噪声对人的身心会造成长期的危害,且防治难度极大,建筑工程中使用隔声材料已成为一种经济有效的防噪途径。基于噪声的传递和反射模型,阐述了噪声防治的基本方法,并针对不同噪声频段,介绍了隔音频率特性,列举了相关评价指标,在此基础上归纳论述了混凝土墙体、隔音墙板、橡胶减震垫、空间吸声体等对于噪声防治的基本原理、构效关系和结构调控措施等,以期为隔声技术的发展提供一定的理论依据,为隔音材料的选用提供必要的实践参考。
Noise pollution,together with air and water pollution,is one of the three major environmental pollutions today,which has caused long-term harm to human body and mind,and it is very difficult to prevent and control.At present,the use of sound insulation materials in construction projects has become an economic and effective way to prevent noise.Based on the transmission and reflection model of noise,the basic methods of noise prevention are described,For different noise frequency bands,the sound insulation frequency characteristics are introduced,and the relevant evaluation indicators are listed,This paper discusses the basic principles,structure effect relationship and structural control measures of concrete walls,sound insulation wallboards,rubber damping pads,space absorbers and so on for noise prevention and control,in order to provide a theoretical basis for the development of sound insulation technology,and provide necessary practical reference for the design of sound insulation materials.
