measurement microphone / prepolarized / free-field / 1/2"
Bruel and Kjaer
Designed for high‐precision, free‐field measurements where a microphone with high sensitivity is required.
Type 4966 is a robust and stable free‐field microphone cartridge designed for high‐precision acoustic measurements. It is developed and refined for measurements where a high sensitivity microphone with a full 20 kHz bandwidth is preferred and is optimized for use with the protection grid in place.
Type 4966 is prepolarized, so it is well suited for use in batteryoperated equipment and environments with high humidity.
General purpose sound‐measurements
Being prepolarized, Type 4966 can be used with both CCLD* and classical Brüel & Kjær preamplifiers.
