Sound field estimation using two spherical microphone arrays

Abstract

We propose a method of estimating a sound field with two spherical microphone arrays (SMAs). This method estimates plane-wave expansion coefficients of the sound field by using sparse representation modeling in the frequency domain. The dictionary matrix we propose for this modeling achieves the integration of the measurements of two SMAs in a straightforward manner. The effectiveness of the proposed method was evaluated in simulations with computer-generated and measured impulse responses.
