A system and method decreases the transmission of structure-borne noise by cooling
fans to electronic components and structurally integrated enclosures for the electronic
components. The system has a machined isolation plate that fits onto a rear plate
on the structurally integrated enclosure. The cooling fans are fitted onto the
opposite side of the isolation plate. Fitted between the isolation plate and the
rear plate, and/or the isolation plate and the cooling fans are soft elastomeric
isolators. These isolators dampen and prevent the transmission of structure-borne
noise from the cooling fans to the electronic components and the structurally integrated
enclosure. This dampening is advantageous on platforms in which stealth is desired,
such as on submarines.
