Abstract : In the investigation the author adapts the methods of information theory to room acoustics. Consideration of a simple layer potential leads to an integral equation of the second kind which may or may not be homogeneous. An approximate solution of the non-homogeneous equation and resonance frequencies are determined by the discretisation method. The prolate spheroid provides an example of application of this method. The experiments agree with the results obtained by computer analysis.
