Snore detection in a sleep appliance and sleep appliance

A continuous positive airway pressure (CPAP) sleep appliance with snore detection, comprising:

• a blower configured to provide a pressurized flow of breathable gas;
• a patient interface device configured for being worn by a user, the patient interface device further being fluidly coupled to the blower via a patient circuit for delivery of the pressurized flow of breathable gas from the blower to the patient interface device;
• one or more sensors configured to acquire (i) sensor information for determination of (i)(a) a moment or start of inspiration of the user or (i)(b) a moment or start of expiration of the user during the delivery of the pressurized flow of breathable gas;
• a communications module adapted for wirelessly communicating with an app on a mobile device that, when executed, is configured to:
• (i) record, via a microphone of the mobile device, acoustic signals during a period of use of the sleep appliance by the user,
• (ii) analyze, via a processor of at least one of the mobile device, the sleep appliance, or a remote cloud device, the recorded acoustic signals for generating processed audio data that is relevant to detect snoring, wherein analyzing the recorded acoustic signals includes at least using an acoustic model configured to recognize snoring characteristics or events by inspecting transient acoustic pressure levels and/or a frequency spectrum in the recorded acoustic signals, and
• (iii) link, via a communication means, at least one or more of the recorded acoustic signals, the analyzed acoustic signals, and the recognized snoring characteristics or events between (a) at least one of the mobile device or the remote cloud device, and (b) the sleep appliance;
• and
• a controller adapted to operate the sleep appliance for delivery of the pressurized flow of breathable gas to the patient interface device, wherein operating includes snoring detection based on a combination of (i) sensor information obtained from sensors of the sleep appliance and (ii) the processed audio data which is used to detect snoring, and wherein operating further includes generating diagnostic quantitative snoring information.
