Acoustic composite including a stiffening polymer, devices, and assemblies including the same |
| abstract |
A composite that includes an expanded polytetrafluoroethylene (ePTFE) membrane having a porous microstructure. The porous microstructure of the ePTFE membrane is impregnated with a stiffening polymer. An acoustic device assembly that includes the composite and an acoustic device is also described. The composite and the acoustic device assembly can exhibit an insertion loss of less than 7dB at 1 kHz when measured by the Acoustic Response Measurement ("ARM") Test. |
