Asymptotic modal analysis of a rectangular acoustic cavity
excited by wall vibration, AIAA J. (USA), vol. 30 no. 5 (1992),
pp. 1191 - 8 .     (last updated on 2007/04/10)      Asymptotic
medal analysis, a method that has recently been developed for
structural dynamical systems, has been applied to a rectangular
acoustic cavity. The cavity had a flexible vibrating portion on
one wall, and the other five walls were rigid. Banded white
noise was transmitted through the flexible portion (plate) only.
Both the location along the wall and the size of the plate were
varied. The mean square pressure levels of the cavity interior
were computed as a ratio of the result obtained from classical
modal analysis to that obtained from asymptotic modal analysis
for the various plate configurations. In general, this ratio
converged to 1.0 as the number of responding modes increased.
Intensification effects were found due to both the excitation
location and the response loc
