ARRAY MICROPHONE (20 KHZ)
Prepolarized Array Microphone for use in systems requiring a large number of microphones, for example, beamforming arrays, STSF measurements, and non-stationary STSF measurements.
TYPE 4957
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.
