Sound Masking System for Respiratory Device, ResMed
Summary
USPTO granted Patent US12594398B2 to ResMed Sensor Technologies Limited for a sound masking system that detects air leaks from respiratory masks and emits masking sounds. The system includes a microphone, speaker, and control system to analyze audio data and determine if mask leakage noise is occurring, then triggers sound emission to mask the noise. The patent contains 20 claims and was filed on October 4, 2022.
What changed
USPTO granted Patent US12594398B2 to ResMed Sensor Technologies Limited. The patent covers a system and methods for triggering sounds to mask noise from respiratory systems and their components, specifically detecting air leaking from masks during sleep therapy and emitting masking sounds. The system includes a respiratory device, mask, microphone, speaker, and control system configured to analyze audio data and determine if mask leakage noise is occurring, then cause the speaker to emit masking sounds.\n\nFor manufacturers of respiratory devices and sleep therapy equipment, this patent establishes intellectual property rights that may affect product development strategies. The sound masking technology for mask leakage detection represents a potential area for licensing consideration or design-around efforts in CPAP and similar device development.

Abstract
A system includes a respiratory device, a mask, a microphone, a speaker, and a control system. The respiratory device is configured to supply pressurized air. The mask is coupled to the respiratory device and configured to engage a user during a sleep session to aid in directing the supplied pressurized air to the user. The microphone is configured to generate audio data. The speaker is configured to emit sound. The control system is configured to analyze the audio data to determine if noise associated with air leaking from the mask is occurring. Responsive to (i) the analysis resulting in a determination that noise associated with air leaking from the mask is occurring, (ii) the respiratory device determining that air is leaking from the mask, or (iii) both (i) and (ii), cause the speaker to emit the sound to aid in masking the noise associated with the air leaking from the mask.
