Abstract
A unitary gasket component is designed to provide a complex acoustic path for bringing sound to a microphone. The path includes a pre-plenum and apertures to allow external sound into the pre-plenum. The path further includes an acoustic filter communicating with the pre-plenum and defining relatively small openings for sound to exit the pre-plenum. A voice tube extends from the acoustic filter to a microphone plenum, the latter being in direct communication with the microphone.
