Various ‘optimum’ room dimension ratios that have been proposed in the literature are studied and compared. Since each proposal is based on a different criterion, independent objective measures of the acoustic quality of the various room ratios are applied in this work. The most straightforward metric is the flatness of a room’s corner to corner frequency response, but since this is not representative of the variations of the sound pressure within the closed space different metrics are employed to quantify these variations. Simulation results are presented to evaluate the effectiveness of the various ratios for the case of a small and a larger room.
