Low-noise breathing mask

A low-noise breathing mask comprising:

• an elastic liner having a fitting side configured to contact a face of a user and a first connecting side opposite to the fitting side, the fitting side having a first opening through which a mouth and nose of the user can pass, and the first connecting side having a second opening that communicates with the first opening;
• a mask body having a second connecting side and a third connecting side opposite to each other, the second connecting side having a third opening that matches the second opening, and the third opening being connected to the second opening, the third connecting side having a fourth opening for receiving pressurized gas, the mask body also having a cavity communicating between the third opening and the fourth opening;
• and
• a noise reduction component comprising a ventilation opening and a muffler, the ventilation opening being provided in the elastic liner, the muffler having a first surface facing an external environment and a second surface opposite to the first surface, the first surface having a first breathable area exposed to the external environment, and the second surface having a second breathable area exposed to the cavity,
• wherein the muffler is made of noise reducing cotton or noise reducing mesh,
• wherein a portion of the muffler connects to an inner surface of the mask body, and
• wherein a surface area of the first breathable area is between 0.45% to 45% of an outer surface area of the mask body.
