Abstract

The root mean square pressure was calculated with synthetically generated pressure signals for transducers of different size. The transducer diameters were in the range of 0.02 < s*of 12,250. The lower limit of the diameter simulated here was much smaller than diameters reported previously by other workers. Calculated root mean square pressure levels developed in the present work were in good agreement with the measured experimental data.

In order to check the simulated pressure signals, the power spectrum and two point correlation were calculated as well. The power spectra obtained with the smaller transducers were higher in energy level at high frequencies. The shape of the power spectra were similar and over­ all agreement with experimental data was reasonable. The two point correlations were obtained for separation distances of = 1.66, and 13.37. The same convection and decay effects as the experimental data were observed with the calculated correlations. Again, overall agreement with experimental result was quite good.
