Abstract
A technique facilitates acoustic measurement and analysis in a variety of acoustic applications. An acoustic source is provided with a housing, e.g. a cylindrical housing, and a motor located within the housing. A piston is driven by the motor. The acoustic source also is provided with a radiating plate mounted along the housing and exposed to an environment surrounding the housing. A fluid passage contains actuating fluid and extends between the piston and the radiating plate. The piston and the radiating plate are linked by the fluid passage such that reciprocation of the piston by the motor causes oscillation of the radiating plate to create an acoustic signal. In some applications, a plurality of radiating plates and/or a plurality of motors may be arranged to enable monopole, dipole, cross-dipole, and/or quadrupole measurements.
