Surface, Intensity, and High Temperature Microphones

 

Array Microphones
Back to Top

130 Series Prepolarized ICP® Array microphones are a cost-effective alternative to precision 377 Series microphones and are suitable for measuring sound within the normal range of the human hearing capability. 130 series of array microphones are single piece units with a built-in preamplifier, and are used in a wide range of applications including holography, sound pressure mapping, noise source identification, beamforming, and other large channel count acoustic tests.
