Comparison of the Two-Microphone Method and a Modal Decomposition Method for Acoustic Impedance Testing [PDF]

12th AIAA/CEAS Aeroacoustics Conference (27th AIAA Aeroacoustics Conference), 2006
Accurate duct acoustic propagation models are required to predict and mitigate radiated aircraft engine noise. These models ultimately rely on acoustic impedance measurements to characterize candidate engine nacelle liner materials. This paper compares two different methods for normal incidence acoustic impedance testing: the two-microphone method (TMM)
