Abstract: A microphone porting and venting assembly (100) is formed of a remote support substrate (118) providing a (130) acoustically resistive element with dedicated venting cavities (132) along with an external baffle (220) providing acoustic channels (212, 214, 216) which further provide water drainage and external sound sampling points ( 222, 224, 226). The microphone porting and venting assembly (100) is well suited waterproof, noise cancelling microphone systems.
