A method for designing dimensions of a rectangular enclosure to avoid degeneracy of standing waves, and the corresponding computer aided design software are presented in this paper. A math model to calculate many dimensions in favor of avoiding degeneracy of standing waves is created. The similarity of the normal frequencies regarded as degeneracy is limited under a specific condition. Based on the relationship between normal frequencies and the dimensions of a rectangular enclosure, the dimensions to avoid degeneracy can be chosen. Also a Computer Aided Design program is developed to identify the dimensions that can be applied in dimensions design of loudspeaker’s cabinet or room conveniently to get the best acoustic effect.
