The aim of barrier design is to reduce the acoustic energy transmission. To understand the characteristics of the specific acoustic impedances of barrier materials and eventually to take the advantage of the characteristics enables an engineer to design a highly effective barrier. On the basis of the relationship between the acoustic impedance and the transmission and reflection of sound waves one can design a barrier interarranged the medium which will get better isolating result than the barrier of the same thickness of single material. Apply the Snell law and select a high sound velocity medium and settle it in definite angle. or apply the mass effect law of sound transmission loss and select the barrier material of high surface density all will have a significant reduction of the sound pressure level in the shielding area.

设计屏蔽目的是减小噪声能量的传播。掌握屏蔽材料的阻抗特性,合理地利用这个特性,就能设计出高性能的屏蔽。从阻抗对声波的传导及反射的关系,将不同阻抗的介质设计“错配”,要比单一材料同样厚度的屏障能有更高的隔声效果。应用Snell定律对二种阻抗差很大的材料将界面安排成一定角度;应用声传导的质量效应,选用表面质量大的材料作屏蔽,都能使屏蔽区的噪声级有明显降低。
