Acoustic radiation pressure on a rigid sphere in a spherical wave field

An analysis has been made of the acoustic radiation pressure acting on a rigid sphere in a spherical sound field for the purpose of completing the work of Embleton [J. Acoust. Soc. Am. 26, 40–45 (1954)] from the angle of practical application. His presentation has been simplified mathematically and improved into a more general form. Numerical calculations have been made with particular emphasis on the difference from the results for incident plane progressive waves as a function of the density of the sphere, the size parameter, and the distance of the sphere from the sound source.
