Abstract
A method of controlling a function of an acoustic detector includes storing a reference power spectrum of a reference acoustic signal, the reference power spectrum being associated with a mode of operation of the acoustic detector; receiving an acoustic sound signal, the acoustic sound signal including a tone and harmonic tones; generating a real-time acoustic power spectrum of the acoustic sound signal responsive to the receiving of the acoustic sound signal; and performing the mode of operation when a comparison of the real-time acoustic power spectrum with the reference acoustic power spectrum indicates that the acoustic sound signal is a control signal.
