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.
