Systems and methods implement a status assessment of a respiratory device with sound evaluation. In some versions, the system may include a motor operated pressure generator to generate airflow through an air circuit to a patient interface. The system may include a transducer producing a signal representing sound of the generator in the circuit. The system may include a controller, such as with a processor, for generator control. The system, such as with the controller, computes a sound representation in the frequency domain. The system applies, to the frequency domain representation, any one or more of an integer-multiple function, non-integer-multiple function, a statistical correlation function and resonant frequency function, such as of a fundamental frequency attributable to motor operation. The system may derive a noise vector with data from the function(s). The system may classify the vector to obtain a status indicator of the generator and generate indicator related output.
