The application discloses a noise attenuating system () for use with a positive airway pressure system providing a flow of gas, comprising: an expansion chamber () having a volume; an intake tube () having an inlet () and outlet port or portion separated by a length, wherein a portion of the inlet port or portion extends outside of the expansion chamber; and either: a noise attenuator () having a bottom and protruding sidewall forming a cavity, wherein the noise attenuator is positioned near the inlet portion of the intake tube such that a portion of the intake tube extends into the cavity of the noise attenuator; or: an acoustic deflector () positioned near the outlet port or portion of the intake tube, wherein noise is deflected away from the outlet port or portion of the intake tube. The application also discloses positive air pressure apparatus () comprising a housing (), first and second acoustic chambers, an intake vent or port () in the first chamber, an inlet port or tube coupling the first and second chambers, a noise attenuator in the first chamber, and a blower unit () in the second chamber.

Systems and methods for providing low-noise positive airway pressure

The systems and methods described herein provide a quiet, light-weight, and portable system and apparatus for providing positive air pressure to a patient. The systems may include a housing with an inlet port, a vibrationally isolated blower unit positioned in an inner chamber, and an outlet port for delivery of the pressurized air from the blower unit. The inlet port and outlet port may each have a tube with dimensions that are defined in relation to the inner chamber so as to reduce the overall noise output of the system.

Portable positive airway pressure apparatus and method for attenuating the noise emitted therefrom

Positive airway pressure sound reduction device

The systems and methods described herein include a low-noise apparatus for providing positive air pressure to a patient. The systems may include a housing with an inlet port, a vibrationally isolated blower unit positioned in an acoustic chamber, and an outlet port for delivery of the pressurized air from the blower unit. The acoustic chamber may include noise attenuators, such as walls, which adjust airflow so as to reduce the overall noise output of the system.
