The power radiated by a slowly moving accelerated acoustic point dipole

This article considers the acoustic analog of a nonrelativistic accelerated point dipole. Having derived the source density of an acoustic point dipole, the velocity potential is calculated to find the energy flux contributing to the radiated power. A low-speed approximation simplifies the calculations considerably, and the radiated power is obtained. The result is finally applied to the special case of a small rigid body and to simple harmonic oscillations of a sphere.
