Abstract
An airborne noise reduction device includes a fixed-volume container having two opposing flat ends and two opposing symmetrical non-flat sides; an inlet port configured to face into a first room; an outlet port configured to face into a return air system; a diverter centrally mounted within an inside chamber to the two opposing flat ends of the fixed-volume container; and acoustic insulative material affixed to surfaces of the two opposing flat ends, the two opposing symmetrical non-flat sides, and the diverter within the inside chamber, wherein a combination of a geometry of the fixed-volume container and an absorption coefficient of the acoustic insulative material is configured to reduce an apparent sound index value of a sound source emanating from a second room connected to the return air system and received into the first room.
