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

사용자 시나리오

  • 제트 엔진 근처와 같은 높은 음압 수준을 측정하는 데 적합합니다.
    • 144dB까지의 넓은 동적 범위를 가지고 있기 때문입니다.
  • 마이크가 사용자와 다른 마이크로폰에서 멀리 떨어져 있는 상황에서 측정하기 전에 마이크의 상태를 확인하는 데 적합합니다. 예를 들어, 통과, 비행 및 분산 측정과 같은 경우입니다.
    • 신호를 전송하여 사용자가 마이크의 상태를 확인할 수 있도록 하는 CIC(전하 주입 보정) 기능이 있기 때문입니다.
