| Sl.No. | Synosis Points | |
| 1 | Specifies a method for the determination of the sound absorption coefficient, reflection factor, surface impedance or admittance of materials and objects. | |
| 2 | 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 sinusoidal plane wave with the plane wave reflected from the test object. | |
