Efficient 3-D Sound Field Reproduction

A method is presented for efficient sound field reproduction with a loudspeaker array constituted by multiple sound sources which are three-dimensionally distributed. The physical reproduction of several target sound fields is investigated when the target sound fields are surrounded by multiple sound sources. A cost function to be minimized has been developed to obtain the optimal solution with reasonable energy distribution and sufficient sweet area when the distribution of loudspeakers is non-uniform. The performance of the proposed method is verified by the results of computer simulations and subjective tests in the cases of NHK 22.2 and ETRI 10.2 channel configurations.
