Acoustics. Determination of sound absorption coefficient and impedance in impedance tubes - Transfer-function method Ingestion-build-98192 10 Sampling device deployment and1 Scope This test method covers the use of an impedance tube, two microphone locations and a digital frequency analysis system for the determination of the sound absorption coefficient of sound absorbers for normal sound incidence. It can also be applied for the determination of the acoustical surface impedance or surface admittance of sound absorbing materials. Since the impedance ratios of a sound absorptive material are related to its physical
