Lightweight acoustic absorbers. The acoustic absorbers absorb energy during launch of a vehicle by a rocket, and are adapted to line the inside of a cavity of a fairing containing a vehicle. The absorbers comprise acoustic absorbing members, and a layer substantially surrounding the acoustic absorbing member which is substantially impermeable to contaminating particulates found within the fairing, and substantially impermeable to any contaminants which may be emitted by the acoustic absorbing member. A plurality of vents are cut in the layer, and a filter is placed over the vents to filter out any contaminants. The vents allow the gases within the fairing and the acoustic absorbing member to pass therethrough, thereby compensating for differential pressure.
