Previously, an analysis of the acoustically coupled, axisymmetric, elastic excitations of a fluid‐loaded, prolate spheroidal target was presented [D. H. Trivett, G. S. Sammelmann, and R. H. Hackman, J. Acoust. Soc. Am. Suppl. 1 81, S13 (1987)]. At this meeting, a controversy arose as to the phase speed of the elastic excitations. Here, direct experimental and theoretical evidence is presented that supports our contention that the velocity of propagation of the elastic waves that propagate on an elongated solid target at low frequencies is essentially the bar speed. |
