Description
Array Microphone Type 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
The preamplifier in the array microphone is of the industry-standard CCLD type allowing the use of only one cheap coaxial cable for signal, power supply, and TEDS.
The array microphone is supplied in a hard box with up to six microphones delivered in a standard microphone box. Seven or more microphones are delivered in a multi-microphone suitcase.
