This sequential paper describes a comparison between the simple closed solution proposed in a previous paper [Z. Ye, J. Acoust. Sec. Am. 101, 1945-1952 (1997)] with the exact solution for scattering of acoustic waves by gas-filled prolate spheroids at low frequencies. The analysis and comparison show that the low-frequency acoustic scattering by prolate spheroid gas bubbles has resonance features, and can be rather accurately described by the proposed simple formula. It is shown that the results from the simple analytic solution agree remarkably well with those obtained by the exact solution. (C) 1998 Acoustical Society of America. [S0001-4466(98)01402-7].
