The subject transducer was designed and constructed at the USRD, utilizing ceramic piezoelectric cylinders. The transducer is a line of 20 modified barium titanate end-capped ceramic cylinders 3.81-cm long x 3.81-cm o.d., having the wall thickness 0.32 cm. Spacing between ends of the ceramic cylinders is 1.5 cm. The line of cylinders in the experimental model is enclosed in Tygon B 44-3 tubing polyvinyl chloride, which is filled with air-free castor oil. Free-field voltage sensitivity and directivity in the XZ vertical plane were measured.
