Prepolarized Array microphones are a cost-effective alternative to the 377 series and are suitable for measuring sound within the normal range of the human ear. PCB®’s 130 series of array microphones are single piece units that include a built-in preamplifier. The array microphones have excellent phase specifications. Using multiple microphones and spacing them in a predetermined pattern coordinated with the proper software, special transformation of a complex sound field is projected to effectively map the acoustic energy flow. End users can now determine the speed and direction of sound. With the value that the array microphones offer this makes them an excellent choice for noise identification, near field acoustic holography, sound pressure mapping, beamforming and other large channel count applications.

Transducer Electronic Data Sheets (TEDS) enhance the identification of each microphone. All PCB® array microphones come standard with the TEDS chip and are compliant with the IEEE 1451.4 standard.
