Abstract
An electronic device having a microphone behind a water resistant, air-impermeable membrane is disclosed. Embodiments include a trapped volume of air between the membrane and the microphone. A barometric equalization element may define an acoustic leak path, e.g., a tortuous leak path, between the trapped volume of air and an encased space within a casing of the electronic device. Other embodiments are also described and claimed.
