properties of air
Examples
- The cavity depth between the rigid panel and absorption material is adjusted in order to make the surface characteristic impedance of the absorption material mathch the surface characteristic impedance of the air , so the absorption coefficient is the maximal
该系统由一层吸声材料和可以移动的刚性板组成，调节刚性板与吸声材料之间的空腔深度，使得吸声材料的表面特性阻抗和空气的特性阻抗相匹配，从而使吸声系数达到最大。
