“…Majority of studies dealt with sound radiation of a single vibrating surface such as a piston, membrane, plate, or shell, where the fluid loading influences considerably responses of vibrating structures. Literature studies can be divided into three major groups dealing with sound radiation of a single surface source , a system of two or more surface sources [31][32][33][34][35][36][37][38][39][40][41], and systems of active control of noise and vibrations [42][43][44][45][46][47][48][49][50][51][52][53][54].…”

This study focuses on the problem of sound radiation by two concentric clamped flat plates, circular and annular, into the half-space. The system of three coupled differential equations comprising two equations of motions of plates and the wave equation, is solved exactly. Vibrations of plates are axisymmetric and time-harmonic with a single excitation frequency. The initial phase difference of excitations can be nonzero. Attenuation due to fluid loading and material damping is included. Kirchoff-Love and Kelvin-Voigt theories are applied. The effect of initial phase difference of excitations on the acoustic power radiated is examined as well as errors resulting from neglecting the fluid loading.
