A system and method are disclosed for enclosing electronic equipment in a noiseproofed and ventilated enclosure. This includes supplying air to an enclosure and removing air from the enclosure through acoustic chambers attached to the enclosure. The acoustic chambers can be constructed of materials or be treated with materials that have noise-absorbing or noise-abating properties. In addition, the acoustic chambers can contain baffles that prevent noise that has entered the acoustic chamber from leaving the chamber. And, the system and method can use a cable egress port that allows cables and wiring to pass through the egress port while blocking the transmission of noise through the egress port.
