Acoustic noise suppression device

An acoustic noise suppression device, comprising:

• a plurality of exhaust chambers adapted to interface with at least one exhaust port of an embedded computer chassis, wherein the at least one exhaust port passes cooling air from at least one exhaust fan;
• a v-shaped deflector adapted to divide and direct the cooling air to the plurality of exhaust chambers;
• and
• noise suppression media coupled to the plurality of exhaust chambers, wherein the noise suppression media modifies a flow vector of the cooling air, and wherein the acoustic noise suppression device decreases a sound level created by the at least one exhaust fan.

A method of attenuating noise generated by at least one exhaust fan of an embedded computer chassis, comprising:

• providing a plurality of exhaust chambers adapted to interface with at least one exhaust port of an embedded computer chassis;
• the at least one exhaust port passing cooling air from at least one exhaust fan;
• a v-shaped deflector dividing and directing the cooling air to the plurality of exhaust chambers;
• modifying a flow vector of the cooling air using noise suppression media coupled to the plurality of exhaust chambers;
• and
• decreasing a sound level created by the at least one exhaust fan.
