Abstract
An acoustic protective cover assembly comprising a porous membrane and an acoustic gasket is disclosed. The porous membrane is bonded to the acoustic gasket at a peripheral region, the membrane is left unhanded at a central region. The acoustic gasket comprises a composite of a porous polytetrafluoroethylene (PTFE) polymer matrix of polymeric nodes interconnected by fibrils, resilient expandable microspheres embedded within the matrix.

An acoustic protective cover assembly comprising:
- a. an acoustic gasket comprising a composite of a porous expanded polytetrafluoroethylene (PTFE) polymer matrix having polymeric nodes interconnected by fibrils and resilient expandable microspheres within the matrix, and
- b. cover material bonded to said acoustic gasket at a peripheral region of the cover and unbonded at a central region of the cover.
An acoustic protective cover assembly comprising:
- a. an acoustic gasket consisting of:
- i. a porous polytetrafluoroethylene (PTFE) polymer matrix having polymeric nodes interconnected by fibrils,
- ii. resilient expandable microspheres embedded within the matrix, and
- iii. elastomer disposed within the matrix
- b. a cover material adjacent to the acoustic gasket such that the gasket contacts a peripheral portion of the cover material.
An acoustic device having an acoustic transducer, an aperture for the passage of acoustic energy and an acoustic cover assembly covering the aperture, the acoustic cover assembly comprising:
- a. an acoustic gasket surrounding the aperture, the gasket comprising a composite of a porous expanded polytetrafluoroethylene (PTFE) polymer matrix of polymeric nodes interconnected by fibrils and resilient expandable microspheres within the matrix and
- b. a cover material bonded to said acoustic gasket and covering the aperture.
A method of covering an aperture of an acoustic device comprising
- a. surrounding the aperture with an acoustic gasket, the acoustic gasket comprising a composite of a porous expanded polytetrafluoroethylene (PTFE) polymer matrix of nodes interconnected by fibrils and resilient expandable microspheres within the matrix, and
- b. bonding a cover material to the acoustic gasket wherein the cover material covers the aperture.
