ACOUSTIC TREATMENT IMPEDANCE MODELS FOR HIGH FREQUENCIES
, 1997The ability to design, build, and test miniaturized acoustic treatment panels on scale model fan rigs representative of the full-scale engine provides not only a cost-saving but an opportunity to optimize the treatment by allowing tests of different ...

Effect of finite ground impedance on the propagation of acoustic pulses
, 1983The propagation of an acoustic transient in the vicinity of a finite impedance ground plane has been numerically simulated. A waveform characteristic of a small explosive charge was selected for analysis.

Elastic characterization of closed cell foams from impedance tube absorption tests.
Journal of the Acoustical Society of America, 2007A method is presented to determine the bulk elastic properties of isotropic elastic closed-cell foams from impedance tube sound absorption tests. For such foams, a resonant sound absorption is generally observed, where acoustic energy is transformed into

Impedance Eduction in Large Ducts Containing Higher-Order Modes and Grazing Flow
, 2017Impedance eduction test data are acquired in ducts with small and large cross-sectional areas at the NASA Langley Research Center. An improved data acquisition system in the large duct has resulted in increased control of the acoustic energy in source ...
