Identifies the direction of the electret microphone source

Device, the 8-pin output can be used as virtual ground. MIC2 were added to the signal picked up by the + difference amplifier A2, an input in Figure 7, R8 and the resistance of the first two microphone distance d between the core end of the diaphragm, so that the pressure to make the two form a pressure transducer differential transducer.
