Components of the new Penn Detail of the resonator lid that forms the partition between the twin resonant cavities excited by the small loudspeaker used in the new Penn State sonic gas analyzer. The two microphones are connected electrically out-of-phase to cancel noise and enhance the differential signal of interest produce by the two out-of-phase resonators on either side of the partition.
