For reproducing complex sound fields the process should take into account the desired sound field, the design of the source transducer, and the acoustics of the environment. In this work a source array is designed to achieve enhanced performance utilizing the acoustic holography technique based on the inverse boundary-element method. Because the proposed method deals with the near-field condition, it is relevant to small listening spaces, which exhibit a mixed combination of near, far, and reverberant fields. In a test example, the target sound field was successfully obtained by both simulation and measurement.
