An acoustic dampening sleeve for electronic equipment and a method of making the same is disclosed. An enclosure for abating noise generated therein includes a housing having a structure defining an internal chamber that has ventilation openings for the ingress and egress of cooling air. The structure cooperates with equipment disposed therein to define intake and exhaust plenums. Air outside the structure passes through the housing ingress opening, into the intake plenum, through the equipment, into the exhaust plenum, and exits the structure through the housing egress opening. The ingress and/or egress openings include baffles. The baffles comprise a resilient material defining openings in fluid communication with the internal chamber and a space outside the housing. The baffles are disposed to prevent or reduce a line of sight between the inside of the structure and the outside of the structure while maintaining open vent channels between the baffles. |
