Abstract

The technology encompassed by the current disclosure generally relates to membrane composites that can be used in acoustic venting assemblies. In one embodiment of the technology disclosed herein, a venting media composite has a microporous membrane layer and a coating on the microporous membrane layer to form a composite. The basis weight of the composite is at least about 0.5% higher than a basis weight of the microporous membrane layer without the coating. In some embodiments the composite has a decreased insertion loss than its membrane-only counterpart.
