The recently reported measurements of the ultrasonic attenuation of both longitudinal and transverse waves in a pure niobium superconductor by Carsey and Levy are analyzed on the basis of a two-band description of the superconducting state. It is seen that some of the ambiguities resulting from a single-band analysis are not present in the two-band analysis.
