Description
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.
- Precision sound‐measurements
- General purpose sound‐measurements
- Electroacoustic measurements
USER SCENARIOS
- Suitable for measuring high sound pressure levels – such as in the proximity of a jet engine
- Because it has a wide dynamic range all way up to 144dB
- Suitable for checking the condition of a microphone before measuring, in situations where the microphone is a distance from both the user and other microphones, such as in pass-by, flyover and distributed measurements.
- Because it features CIC (charge injection calibration) that allows the user to check the microphone’s condition by sending a signal
