Measurement microphone CRY375

externally-polarizedfrequency1/2"

CRY375 is a 1/2'' external-polarization 200 V free-field measurement microphone that measures the undistorted true sound pressure of the microphone before it is placed in the sound field. The presence of the microphone in the sound field will affect the sound field and change its high-frequency sound field. Based on this characteristic, the free-field microphone has its frequency response adjusted to compensate for errors brought to high-frequency sound pressure in the sound field.
