4966-H-041

TYPE 4966

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.

Code Standard Polarization Freq. range (low) Dyn. range (low) Dyn. range (high) Higher operating temperature Higher operating temperature
-4966-H-041- ANSI S1.4,IEC 61672 CCLD 6.3 Hz 16.5 dB 134 dB 125 °C 257 °F
-4966-A-031- IEC 61672,ANSI S1.4 CCLD 3 Hz 18 dB 131 dB 65 °C 149 °F
-4966-L-001- ANSI S1.4,IEC 61672 Classical 6.3 Hz 15.2 dB 144 dB 60 °C 140 °F
-4966-A-041- ANSI S1.4,IEC 61672 CCLD 12.5 Hz 16.5 dB 134 dB 60 °C 140 °F

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.
