Abstract

A method for auralizing arbitrary radiation patterns of acoustic sources inside a real room is presented. The method utilizes laser induced breakdown (LIB) as a point source. In this study we (1) demonstrated the performance of a volumetric array of LIBs for synthesizing arbitrary radiation patterns, (2) auralized the radiation pattern of a loudspeaker and compared the measured and synthesized impulse responses in a reverberant room, and (3) evaluated the method using listening tests. The synthesized room response matched the target response well both in room response reconstruction and in listening tests.
