1. A method for determining an acoustic driving frequency for a diamond of a diamond nitrogen vacancy (DNV) sensor comprising:

  • acoustically driving the diamond having nitrogen vacancies of the DNV sensor at a first frequency using an acoustic driver;

    detecting, by a processing system, a first set of NV0 photon emissions and a first set of NV

    photon emissions from the DNV sensor;

    acoustically driving the diamond of the DNV sensor at a second frequency using the acoustic driver;

    detecting, by the processing system, a second set of NV0 photon emissions and a second set of NV

    photon emissions from the DNV sensor; and

    selecting, by the processing system, the second frequency for acoustically driving the diamond with the acoustic driver to manipulate a phonon spectrum based on a wavelength difference between a peak of the second set of NV0 photon emissions and the second set of NV

    photon emissions from the DNV sensor.
