Array MicrophoneType 4957 is used in combination with other array microphones, and is designed with specified and stable phase-matching over wide ranges of temperature and humidity.

A rugged protection grid provides an integrated heat shield. The microphone is front-vented for pressure equalization. 

  • Measurements using:
    • Spatial Transformation of Sound Fields (STSF) Type 7688
    • Non-stationary STSF Type 7712
    • Beamforming Type 7768
  • Hand-held array measurements
  • Simultaneous recording of time signals in medium to large microphone arrays, for example, simulated pass-by measurements
  • Cost-effective in-car measurements
