Holographic Design of a Source Array Achieving a Desired Sound Field

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.
