Abstract
Methods based on perturbation theory are proposed for calculating reso nance frequencies in the enclosures of acoustical systems having a com plex geometry. Computational methods using the boundary-element approa ch and eigenfunction expansions of the structure of the internal sound fields are investigated. Software packages have been written for the IBM-XT computer, and calculations for various design configurations ar e reported.
