Sound Field Reproduction by Higher-Order Mode Matching Based on Equivalent Source Method
Mode matching (MM) is a sound field reproduction method based on spherical harmonic expansion. In this study, we propose a higher-order MM method using a limited number of microphones based on the sparse equivalent method. Simulation experiments show that the proposed method achieves a significant improvement in reproduction accuracy.
