The theory of King for the radiation pressure exerted by plane progressive waves on spheres has been used to compute the constants for spheres of radii (r) of the order of a wave-length (λ) of the sound in the medium. These are given for integer values of α = 2πr/λ from 1 to 11, and for α = 15 and 20.

Recently several workers have developed theories to explain the characteristics of the pressure wave associated with thunder. Few et al. [1967] presented approximate calculations for a cylindrical shock wave. Jones et al. [1968] have extended the strong-shock solution into the acoustic region.

Mechanical Pressure-Gradient-to-Pressure Sound Transducer
The Journal of the Acoustical Society of America, 1961In places of high ambient-noise level, the use of electrical devices as an aid to speech communication is sometimes precluded by safety requirements. A mechanical device may then be used provided that the individuals concerned are close to each other.

Unidirectional Underwater-Sound Pressure-Gradient Transducer
IEEE Transactions on Sonics and Ultrasonics, 1970Results are presented for the design, construction, and calibration of an experimental, low-frequency, pressure-gradient, underwater sound transducer that utilizes a liquid-filled, acoustic phase-shift network to obtain a unidirectional (cardioid) directivity response over a prescribed frequency range.
