The acoustic performance of a nominally locally reacting liner specimen mounted in a grazing incidence impedance tube is analyzed. Measured standing wave ratios and null positions are compared with those predicted by a finite-element algorithm. Differences between measured and calculated wave structures may be due to extended reaction effects. (DePo)
