Zusammenfassung:	An acoustically insulated machine including a source of noise positioned within a housing, a first insulation member positioned within the housing and including a first porous sound absorbing layer and a first dense layer, and a second insulation member positioned within the housing and including a second porous sound absorbing layer and a second dense layer. The first insulation member being is positioned closer to the internal source of noise than the second insulation member and the first insulation member being spaced apart from the second insulation member such that an air gap is formed between the first insulation member and the second insulation member.
