ABSTRACT Reproduction of a soundfield is a fundamental,problem,in acoustic signal processing. A common,approach is to use an array of loudspeakers to reproduce the desired field where the least square method is used to calculate the loudspeaker weights. However, the least square method involves matrix inversion which may lead to errors if the matrix is poorly con- ditioned. In this paper, we derive a new theoretical continu- ous loudspeaker method,to obtain the loudspeaker aperture function in order to avoid matrix inversion. In addition, the aperture function obtained through continuous loudspeaker method,reveals the underlying structure of the solution as a function of the desired soundfield, the loudspeaker positions and the frequency. Results are verified through simulations. Index Terms— acoustic field, least square method, ma- |
