Response to “Comments on ‘On Dowell’s simplification for acoustic cavity-structure interaction and consistent alternatives [J. Acoust. Soc. Am.127, 22–32 (2010)]’ ”

Dowell [J. Acoust. Soc. Am. 128, 1–2 (2010)] commented on several aspects of an approximation commonly invoked to model the coupling of an acoustic cavity and a surrounding structure. Additional observations regarding these issues are provided herein, as well as an explanation of discrepancies in the low frequency pressure predicted by the approximation.
