½ - INCH FREE-FIELD MICROPHONE, PREPOLARIZED, 5 HZ – 20 KHZ
Free-field microphone designed for high‐precision and high sensitivity measurements with a frequency response of 5 Hz to 20 kHz.
FAMILY 4966
A robust and stable free‐field microphone cartridge designed for high‐precision acoustic measurements. Type 4966 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.
Microphone Type 4966 is prepolarized, so it is well suited for use in battery-operated equipment and environments with high humidity.
