Natural resonant frequencies of oblate acoustical resonators with either perfectly soft or perfectly rigid boundaries are calculated by locating the zeros of Rmn(1)(−ih, iξ) and Rmn(1)′(−ih, iξ). These frequencies are normalized to those of the corresponding modes of a spherical cavity with the same volume and presented for various ratios of major to minor axes.
