Abstract:

In the nearfield model of the parametric radiator, source levels were obtained by assuming the primary wave to be plane-cylindrical or diverging-conical, depending on whether the observation range was less or greater than the Rayleigh distance. The two cases are now combined by means of the horn model, which approximates primary wave diffraction for a piston source. Saturation effects are also incorporated by means of a nonlinear attenuation approximation. Author
