SparkFun Electronics electret condenser microphones bob-12758
A schematic and photograph are shown in ( A ) and ( B ), respectively. Two circular arrays with each 114 <t>microphones</t> record the pressure fields ( C ). Using the recordings, an FPGA-based low-latency control system ( D ) performs the real-time wavefield extrapolation to predict the input signals for the control loudspeakers ( E and F ).

Article Snippet: Instead of directly measuring the normal particle velocity and pressure on S rec , as dictated by the theory of the underlying control algorithm (see Supplementary Materials for details), we use two circular arrays of pressure microphones with radii of 35.3 and 37.3 cm, respectively, each consisting of 114 electret condenser microphones (SparkFun Electronics, BOB-12758 and COM-08635; ).
