ICP® array microphones are a cost-effective alternative to measuring microphones. They are suitable for sound measurement in the field of human hearing. The array microphones of the series 130 already contain the amplifier and are characterized by an excellent phase behavior. With several array microphones arranged at certain distances from each other, the spatial transformation of a complex sound pressure field can be developed by means of suitable measuring and analysis systems in order to effectively map the acoustic energy flow. With array microphones, developers can determine the exact source of a sound and make statements about the speed and direction of the sound. Array microphones are an ideal solution for applications such as noise identification, near-field holography, sound pressure mapping, beamforming, and other tasks that require many measurement channels. Above all, the TEDS functionality offers the user great advantages, such as time savings during test preparation and an improvement in the consistency of his measurement data.
