Abstract :
To obtain the acoustic source condition from a given sound field data in an inverse manner is useful in achieving the target sound field in a detailed field distribution. A multi-unit acoustic source system comprises many loudspeakers to improve the performance and sometimes a modular array system can be used to realize a prescribed radiation pattern. To obtain an applicable solution for modular source system by inverse approach, relative magnitude and phase between sources in the same module are maintained at the same values. In this paper, a basic approach to practice the general inverse design method was studied. Two methods using the boundary element method and the equivalent source method were suggested. Validity of the suggested method was confirmed through a test example with the highly directional loudspeaker module.
