吸声与隔声均是噪声控制中的重要技术措施,两者有着本质的区别,但实际应用中又常有联系。不熟悉噪声控制技术的人常把两者混淆,在应用中常常摘锗,以致达不到预期效果。 原理不同 噪声在传播途径中若碰到一个界面很大的屏障时,它的能量一部分被屏障反射,另一部分被材料吸 收,还 Both sound absorption and sound insulation are important technical measures in noise control. There is an essential difference between the two, but the actual application is often linked. People who are unfamiliar with noise control technology often confuse the two, often extracting germanium in their applications, so that they can not achieve the expected results. Principle Different noise in the transmission path if you encounter a large interface barrier, it is part of the energy barrier reflection, the other part of the material absorption, but also
