An acoustic technique is described which permits precise measurement of phase velocity in liquids or gases with high attenuation ( c1 >I0 cm-l) utilizing a thin, variable path length acoustic cavity formed by a quartz transducer and a piezoelectnc bimorph. The path length can be changed manually or
