泡沫玻璃制品是90年代国内研制成功的新型吸声材料。它具有良好的声学性能,它是无机材料,具有不燃、不腐蚀、不霉烂、不吸水、容重轻、耐久性强,可任意切割,施工简单和维护方便等特点,特别适合于地下工程和地上潮湿环境中使用。本文着重介绍了泡沫玻璃材料的主要物理力学性能,不同厚度的吸声系数,背面有无空腔的吸声系数的影响数据以及与常用吸声材料的枝术参数对比等。文中还介绍了吸声降噪的计算方法,并有工程应用实例及其测试数据等。
Foam glass products is the 90’s successful development of a new type of sound-absorbing materials. It has good acoustic properties, it is inorganic materials, with non-flammable, non-corrosive, not mildew, non-absorbent, light weight, durability, can be arbitrarily cut, simple construction and easy maintenance and other characteristics, especially for underground engineering and the ground Used in humid environment. This article focuses on the main physical and mechanical properties of foam glass materials, the different thickness of the sound absorption coefficient, the back of the cavity with no sound absorption coefficient of influence data and the commonly used sound-absorbing materials and other parameters of the branches compared. The article also introduced the calculation method of sound absorption and noise reduction, and engineering examples and test data.
