This Letter describes a correction to the equations used in Ginsberg [J. Acoust. Soc. Am. 127, 22-32 (2010)] to include the rigid-body (Helmholtz) cavity mode in the modal series solution when using Dowell's method. While the correction is easy to implement, it significantly affects the results and the conclusions when using the modal series solution. Specifically, the correct formulation of Dowell's method now predicts results that agree very well with the exact solution even to the lowest frequencies.
