Beamforming is an important technique in studies involving loudspeaker arrays, and conventional beamforming studies use linear, circular, and spherical arrays. In a previous study, the present authors introduced a model involving two circular loudspeaker arrays to reproduce focused sources; the two arrays have rigid baffles, and their multiple scattering offers better performance. The present paper reports on investigations into implementing beamforming with this array model, the performance of which is evaluated using a minimum-variance distortionless-response beamformer. Numerical simulations show that the proposed method outperforms a single circular array at lower frequencies, and the numerical results agree with those from experiments conducted in an anechoic chamber.
