Ultrasonic audio processing circuitry and a method useful in ultrasonic presence detection. An ultrasonic burst generator produces an ultrasonic burst signal at one or more ultrasonic frequencies, and an equalizer equalizes that ultrasonic burst signal according to frequency response characteristics of the speaker and microphone at those ultrasonic frequencies.

One or more electromagnetically translucent windows or vial-end access points provide access to electromagnetic waves launched or received by one or more electromagnetic antennas at a frequency that is adjusted to match the quantum transition frequency of the gas based on a detected maximum absorption frequency.
