The Model 377A13 prepolarized, 1/2-in. pressure-response-type microphone operates from ICP sensor power and offers an extended frequency capability of 4 to 20 kHz (+2 dB). Designed for applications requiring matching magnitude and phase at any position, the microphone can measure changes caused by microphone presence in the sound field, such as those required in confined spaces like small cavities, couplers, or impedance tubes.
