Patent ID: 7000729

Claim:
An acoustical absorber comprising: a. a first synthetic polymeric scrim layer, b. a first synthetic polymeric film layer, c. an interior fibrous batt layer, d. a second synthetic polymeric film layer, and e. a second synthetic polymer scrim layer, wherein i. the first synthetic polymeric scrim layer has interstices and has a melting point higher than that of the first synthetic polymeric film layer, and the first film fills some of the interstices of the first scrim, resulting in an embedded first scrim/first film combination, ii. the second synthetic polymeric scrim layer has interstices and has a melting point higher than that of the second synthetic polymeric film layer, and the second film fills some of the interstices of the second scrim, resulting in an embedded second scrim/second film combination, iii. the interior batt layer is adhered to the first film layer and the second film layer, and iv. the acoustical absorber is flexible and has an air permeability ranging from about 500 Rayles to about 26,000 Rayles.
