1. A method of one or more processors for monitoring a sleep disordered breathing state of a person, the method in the one or more processors comprising:
extracting one or more respiratory signals from one or more motion signals, the one or more motion signals generated by active non-contact sensing;
extracting one or more energy band signals from a passive signal, the passive signal generated by passive non-contact sensing, the passive signal representing acoustic information detected by a sound sensor;
assessing the one or more energy band signals and/or the one or more respiratory signals to generate one or more intensity signals representing intensity of sleep disorder breathing modulation that comprises a modulation frequency characteristic in a sleep disordered breathing frequency range;
classifying one or more features derived from the one or more intensity signals to generate one or more measures of sleep disordered breathing; and
controlling, with the one or more processors, a change to a setting of a therapy for operating a respiratory therapy device to provide the therapy based on the one or more measures of sleep disordered breathing.
