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.

1. A portable Continuous Positive Airway Pressure (CPAP) apparatus, comprising: a housing, wherein the housing defines a first acoustic chamber and a second acoustic chamber, the first acoustic chamber having a volume and a first inlet port, the first inlet port defining a length and cross-sectional area that is proportionally related to the volume of the first chamber, the second acoustic chamber having a volume and a second inlet port, wherein the second inlet port extends from the first acoustic chamber into the second acoustic chamber;a blower unit that being disposed within the second acoustic chamber; andwherein the first inlet port includes an intake tube which extends from an exterior portion of the second acoustic chamber, passes through an interior portion of the second acoustic chamber, and into the first acoustic chamber. 2. The apparatus of claim 1, wherein the length and cross-sectional area of the first inlet port and the volume of the first acoustic chamber are proportionally related so as to create a low-pass acoustic filter. 3. The apparatus of claim 1, wherein the combined volume of the first and second acoustic chambers is less than 360 milliliters. 4. The apparatus of claim 1, wherein the first inlet port further comprises a first intake tube having a diameter ranging from 0.25 inches to 0.75 inches and a length ranging from 0.25 inches to 3.5 inches. 5. The apparatus of claim 1, wherein the second inlet port further comprises a second intake tube having a diameter ranging from 0.25 inches to 0.75 inches and a length ranging from 0.25 inches to 3.5 inches. 6. The apparatus of claim 1, wherein the housing further comprises an anechoic material disposed therein. 7. The apparatus of claim 1, further comprising an adapter having a proximal end and a distal end, wherein the proximal end is in communication with the blower unit through a blower outlet tube and the distal end extending outward from the apparatus. 8. The apparatus of claim 7, wherein the blower outlet tube defines a sealed air-flow pathway between the blower unit and the adapter. 9. The apparatus of claim 1, wherein the housing further defines a hose port configured to receive a patient interface system. 10. The apparatus of claim 1, wherein the housing further comprises at least one user interface button. 11. The apparatus of claim 1, wherein the housing further comprises a digital display. 12. The apparatus of claim 1, wherein the housing further comprises an acoustically invisible cover positioned over the inlet port of the first acoustic chamber. 13. The apparatus of claim 1, wherein the first inlet port comprises an intake tube which passes through the second chamber into the first chamber and is sealed from the second chamber. 14. The apparatus of claim 13, further comprising an outlet tube extending from the blower in the second acoustic chamber and traversing through the first acoustic chamber and through the housing wall. 15. The apparatus of claim 1, wherein the cross-sectional area and length of the first inlet port is related to the noise generated by the blower, wherein the overall acoustic reduction is balanced with any increase in blower noise generated. 16. The apparatus of claim 1, wherein the volume of the second acoustic chamber is greater than the volume of the first acoustic chamber.
