• In the present study it was clarified that barium titanate transducers, smaller in dimensions than the wave lengths of elastic waves in solids, transmit simultaneously longitudinal, shear and surface waves of ultrasonic frequencies when subjected to an electrical pulse. Directional characteristics of longitudinal and shear waves generated by small transducers in aluminium semi-cylinder was also measured by a pulse method. Experimental values show qualitative agreements with the theoretical predictions of Hirono (1948), and Miller and Pursey (1954). It was made clear from the results of investigation of the propagation of elastic waves in aluminium plate that a transmitter and receiver should be placed in proper positions and directions on surface of solids when small transducers are applied for the detections of shear waves in solids.
