Abstract:

The results are described of measurements of the acoustic field of radiating circular and rectangular apertures and the scattering around a circular disk. The field parameters determined include the pressure, the phase of the pressure, the pressure gradient, and the phase of the pressure gradient. Measurements described are for sonic frequencies in air. Short tone bursts were used in the measurements. The measurement technique described is that of synthesis and analysis of a continuous electrical signal which is in coincidence with a selected portion of the signal representing the pulsed acoustic field variable. Measured results are compared with the results of simple elementary theoretical analyses of the cases considered. Author
