The mean‐square pressure distributions in the ultrasonic fields generated in water by quartz transducers of various shapes were presented on an oscilloscope screen and photographed. The beams, pulsed at an audiofrequency, were swept back and forth

When a small microphone is used in an ultrasonic beam, the direct acoustic signal is mixed with electric pick‐up and reflected signals. The use of pulses may not entirely remove these interferences. The mixing process is analyzed here for a particu

The theory of harmonic growth for finite‐amplitude sound waves in a nondissipative fluid is discussed. The perturbation analysis of such waves in a dissipative fluid has been extended to higher orders of calculation, so that the location of the max
