Design of a Second-Order Soundfield Microphone

Second-order sound-field microphone is desirable for spatial audio recordings and reproduction which uses zero, first and second order harmonics. Recent results in the design and analysis of spherical microphone arrays are employed in this paper to analyze performance and requirements from a second-order soundfield microphone configured as a spherical microphone array. The effect of measurement noise, spatial aliasing, microphone positioning accuracy and microphone response mismatch on overall performance is evaluated both analytically and using simulation. Specifications for high quality second-order microphone are presented, and directions for improving performance are proposed.
