Respiratory Sound Masking System Patent - US12594398B2
Summary
USPTO granted ResMed Sensor Technologies patent US12594398B2 for a system and methods to mask noise from air leaks in respiratory masks. The technology uses microphones to detect mask leak sounds and speakers to emit masking sounds, with 20 claims covering the control system and masking mechanism.
What changed
USPTO granted patent US12594398B2 to ResMed Sensor Technologies for a respiratory sound masking system. The invention includes a microphone configured to generate audio data, a speaker to emit masking sounds, and a control system that analyzes audio to detect air leak noise from CPAP/BiPAP masks and triggers sound masking. The patent contains 20 claims covering the masking mechanism, control logic, and system integration with respiratory devices.
Medical device manufacturers developing sleep therapy products should monitor this patent position. Competitors in the CPAP/BiPAP mask market may need to evaluate whether their products employ similar noise masking technology, as ResMed now holds enforceable patent rights covering this functionality.
What to do next
- Monitor for potential infringement implications
- Review patent claims for product development considerations

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.
