Continuous positive airway pressure cpap device featured with active noise cancellation and method thereof

A method of active noise cancellation with a continuous positive airway pressure CPAP device, comprising:

• delivering a pressurized flow of breathable gas, via a patient interface device fluidly coupled to a base station of the CPAP device via a patient circuit, wherein at least during the delivery of the pressurized flow of breathable gas the CPAP device produces regular or random CPAP device noise;
• recording, via a microphone acoustically coupled to the CPAP device, the CPAP device noise produced by the CPAP device at least during the delivery of the pressurized flow of breathable gas;
• implementing, via a controller, an active noise cancellation (ANC) algorithm for (i) processing the recorded CPAP device noise and (ii) generating a CPAP anti-noise wave signal based on the processed CPAP device noise;
• and
• outputting, via an audio output device coupled to the patient interface device at a predetermined placement location of the patient interface device at least during the delivery of the pressurized flow of breathable gas, a CPAP device noise cancellation audio output signal based on the CPAP anti-noise wave signal, the CPAP device noise cancellation audio output signal configured to reduce noise effects of the CPAP device by eliminating up to a given noise threshold amount of the noise produced by or at the CPAP device.
