1. A system (100) for measuring a concentration of a known component in a gas sample using an acoustic resonance technique, the system (100) comprising:

  • a resonant chamber (110), comprising a wall (112), forming an interior (114), and an opening (116) extending through the wall (112) to the interior (114);

    a sound generator (120), positioned at and acoustically coupled to the opening (116) of the resonant chamber (110) and configured to generate white noise and supply the white noise into the interior (114) of the resonant chamber (110); and

    an audio sensor (140), positioned proximate to and in sound communication to the opening (116) and configured to measure an acoustic spectrum emitted from the interior (114) of the resonant chamber (110) through the opening.
