Abstract
An acoustically reactive composite can include an expanded polytetrafluoroethylene (ePTFE) membrane formed of a highly fibrillated ePTFE microstructure with an elastomer fully impregnated within the ePTFE membrane. The composite can have an acoustic loss of less than 7 dB at 1 kHz and a water entry pressure (WEP) of at least 20 PSI. A layered assembly for protecting an acoustic device can include an acoustically reactive composite as described above and an adhesive layer arranged to define an acoustic cavity. An acoustic device can incorporate an acoustically reactive composite or layered assembly as described above, with the acoustically reactive composite or layered assembly arranged to span an acoustic cavity proximate to a transducer of the acoustic device.
