Eigenfrequencies of a rectangular acoustic resonator with elastic walls
Abstract
A solution is presented for the problem of determining the eigenfrequencies of a rectangular acoustic resonator whose two opposite walls consist of fixed thin elastic plates and the other two walls are absolutely rigid. Approximate formulas are derived for determining the lower frequencies of the resonator. The eigenmodes of the resonator are analyzed.
