Thermoformable acoustic product
First Claim
1. A thermo-formed acoustic product formed from an acoustic sheet with a relatively high flow resistance, and a layer of porous flow resistive spacer material attached to one side of the acoustic sheet and having a flow resistance substantially smaller than the acoustic sheet, wherein the acoustic product has locally reactive acoustic behavior and an overall air flow resistance of between 2800 Rayls and 8000 Rayls.
