Resonant Cavity Microphone at Waldo Alline blog

Resonant Cavity Microphone. A hollow cavity with a narrow sound inlet will resonate acoustically when excited. Ec pulsed cavity was a resonant cavity microphone, intended as a covert listening device (bug), developed and manufactured between 1954 and. An electrical microphone (bswa tech, mpa201) is strategically positioned to capture the sound wave signals at the resonance cavity's terminus.
