Nearfield Pressure Distributions for a Rigid and a Flexing Piston in an Infinite Soft Baffle Available to Purchase

The nearfield pressures of a rigid piston (ka = 0.906 at f = 7.55 kHz) and a flexing piston (ka = 2.4 at f = 20.0 kHz) in an infinite soft baffle were measured in a tank by means of a toneburst technique. The resulting pressure profiles are presented as isobaric contours, comparable to those for pistons in a rigid baffle derived analytically by H. Stenzel [Handbook for the Calculation of Sound Propagation Phenomena, A. R. Stickney, Trans. (Springer‐Verlag, Berlin, 1939)].
