AB  - This paper proposes a control strategy for generating various acoustic radiation patterns associated with a “personalized sound field” using an acoustic source array. A dual-dipole array, which models each loudspeaker as an imperfect dipole and a source signal control algorithm, which effectively considers both energy difference maximization and radiation efficiency are introduced in order to obtain better radiation patterns for generating the desired sound field. With the proposed dual dipole array and control algorithm, a wide controllability from a comparatively low to a high frequency range is obtained, although the array size is small enough to implement in mobile applications. Conceptually novel control strategy proposed enables to cancel out the backward radiation efficiently. The performance of the dual dipole source array is verified by using computer simulations.
