Acoustics — Determination of sound absorption coefficient and impedance in impedance tubes — Part 1: Method using standing wave ratio 声学——阻抗管中吸声系数和阻抗的测定第1部分:驻波比法

发布日期： 1996-12-12

指定用于确定材料和物体的吸声系数、反射系数、表面阻抗或导纳的方法。通过评估管中平面波的驻波模式来确定这些值，该驻波模式由入射正弦波平面波与从测试对象反射的平面波叠加而成。

Specifies a method for the determination of the sound absorption coefficient, reflection factor, surface impedance or admittance of materials and objects. The values are determined by evaluation of the standing wave pattern of a plane wave in a tube, which is generated by the superposition of an incident sinusiodal plane wave with the plane wave reflected from the test object.
