1. A system for measuring a concentration of a known component in a gas sample using an acoustic resonance technique, the system comprising:

  • a resonant chamber, comprising a wall, forming an interior, and an opening extending through the wall to the interior;

    a sound generator, positioned at and acoustically coupled to the opening of the resonant chamber and configured to generate white noise and supply the white noise into the interior of the resonant chamber; and

    an audio sensor, positioned proximate to and in sound communication to the opening and configured to measure an acoustic spectrum emitted from the interior of the resonant chamber through the opening.
