Abstract: While public interest for technologies that produce and deliver immersive VR content has been growing the price point for these tools has remained relatively high. This paper presents a low-cost, high-quality first-order ambisonics (FOA) microphone based on low-noise microelectromechanical systems (MEMS). This paper details the design, fabrication, and testing of a MEMS FOA microphone including its frequency and directivity response. To facilitate high resolution directivity response measurements a low-cost, automatic rotating microphone mount using an Arduino was designed. The automatic control of this platform was integrated into an in-house acoustic measurement library built in MATLAB allowing the user to generate polar plots at resolutions down to 1.8°. Subjective assessments compared the FOA mic prototype to commercially available FOA solutions at higher price points.
