Abstract
Acoustically insulated machines have an internal source of noise and an insulation member. The insulation member may include a plurality of porous, sound absorbing layers and a plurality of dense or facing layers attached to faces of the sound absorbing layers. The dense or facing layers each have a density that is greater than the densities of the sound absorbing layers. The insulation member may be oriented such that one of the dense or facing layers faces toward the internal source of noise. The insulation member may be configured such that most of the low frequency sound energy generated by the internal source of noise is not reflected back into the machine. That is, the dense or facing layer may be configured to allow a majority of low frequency sound energy from the internal source of noise to pass into the insulation member.
