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