21. A method, comprising:
attaching a gasket to an internal surface of a housing, wherein the gasket defines an interior cavity and has a contaminant-proof membrane connected thereto;
coupling a first end of a microphone plug to a microphone such that an acoustic seal between the microphone plug and the microphone is created, wherein the microphone comprises a sound inlet and an acoustic membrane, and wherein a surface area of the acoustic membrane is smaller than a surface area of the contaminant-proof membrane; and
inserting a second end of the microphone plug into the gasket such that the microphone plug is mostly disposed between the contaminant-proof membrane and the sound inlet of the microphone and the microphone plug acoustically couples the contaminant-proof membrane to the sound inlet.
