Two vibrating circular membranes radiate acoustic waves into the region bounded by three infinite baffles arranged perpendicularly to one another. The Neumann boundary value problem has been investigated in the case when both sources are embedded in the same baffle. The analyzed processes are time harmonic. The membranes vibrate asymmetrically. External excitations of different surface distributions and different phases have been applied to the sound sources' surfaces. The influence of the radiated acoustic waves on the membranes' vibrations has been included. The acoustic power of the sound sources system has been calculated by using a complete eigenfunctions system.
