Abstract (en)
[origin: WO2005081226A1] A thermo-formed acoustic product (6) formed from an acoustic sheet (7) with a relatively high flow resistance, and a layer of porous flow resistive spacer material (10) attached to one side of the acoustic sheet (7) and having a flow resistance substantially smaller than the acoustic sheet. The acoustic product (6) has locally reactive acoustic behaviour and an overall air flow resistance of between 2800 Rayls and 8000 Rayls. A decorative facing (9) can be applied to the acoustic sheet (7).
