Abstract
An apparatus for reducing sound levels in an HVAC system, the apparatus including a housing configured to be positioned within an air inlet vent for an HVAC system. The housing includes a first opening configured to intake air and a second opening configured to out put air and a plurality of baffles positioned within said housing, each baffle including a body defining a volume and has a plurality of perforations, wherein each baffle is affixed to the housing and wherein the plurality of perforations are configured to allow airflow through the volume of the body and redirecting sound waves.
Claims19
A sound reducing system for returning air to an air handler in an HVAC system, the sound reducing system comprising:
- an air inlet having a cross-sectional area and in fluid communication with an air handler;
- a housing in fluid communication with the air inlet and dimensioned to correspond with the cross-sectional area of the air inlet, wherein the housing includes a first opening configured to intake air and a second opening configured to output air, wherein the first opening is orthogonal to the second opening;
- and
- a plurality of baffles positioned within the housing, each baffle including:
- a body defining a volume and having a plurality of perforations positioned thereon and facing the first opening,
- wherein each baffle is affixed to the housing, and
- wherein a sound-attenuating media is positioned within the volume;
- and
- wherein the plurality of perforations are configured to allow airflow through the volume of the body of the baffle while attenuating sound waves,
- wherein the housing has a transverse axis and at least two baffles of the plurality of baffles are located on a first side of the transverse axis and at least two baffles of the plurality of baffles are located on a second side of the transverse axis, and
- wherein the housing further includes at least a first cover which covers a first surface orthogonal to a rear surface, a first side, and a second side of the housing.
An apparatus for reducing sound levels in an HVAC system, the apparatus comprising:
- a housing in fluid communication with an air inlet vent for an HVAC system, wherein the housing includes a first opening configured to intake air and a second opening configured to output air, wherein the first opening is orthogonal to the second opening;
- and
- a plurality of baffles positioned within said housing, wherein each baffle includes a body defining a volume and has a plurality of perforations facing the first opening;
- wherein each baffle is affixed to the housing;
- wherein the plurality of perforations are configured to allow airflow through the volume of the body and redirecting sound waves, and
- wherein the housing further includes at least a first cover which covers a first surface orthogonal to a rear surface, a first side, and a second side of the housing.
