The criteria for an “optimum” hydrophone receiving system for underwater acoustic signals are considered, and the equilibrium thermal‐noise pressure spectrum expression is shown.Experimental ambient… (More)

The Corcos model for convective turbulence is equivalent to the problem of an ensemble of plane waves passing through spatial windows with rhombic iso‐amplitude contours. The sharp corners introduce… (More)

A theoretical model for the difference‐frequency radiation from a parametric acoustic array is developed. The (two‐frequency) primary wave is assumed to be radiated by a piston source and may be… (More)

The acoustic noise spectrum associated with the collapse of transient cavities produced by a stirring rod in water was measured in the frequency range 1–3500 kc. While the spectrum, in general, goes… (More)

There is increasing evidence that the low‐frequency sound absorption in the Pacific is less than that in the Atlantic. Thorp's original empirical equation was based largely on North Atlantic data.… (More)

Because it is often impractical to make measurements in the farfield of a parametric acoustic source, it is desirable to be able to predict the farfield from nearfield measurements. A nearfield… (More)

The nearfield of the difference frequency generated by a spherically spreading primary wave can be represented by a triple integral of an oscillating integrand. The computation is facilitiated by a… (More)

A model is presented for predicting source levels and beam patterns generated by parametric acoustic sources of rectangular aperture. This model is a generalization of a previous model for square and… (More)

Computations of effective virtual‐source array lengths for parametric acoustic sources are presented. The effective length is defined as the distance from the primary projector where the… (More)

The pressure wave produced by the collapse of an electrically generated spherical cavity (∼1 cm in radius) in water was measured by means of a small electroacoustic hydrophone (116 in. in diameter)… (More)
