The Fibonacci array is the ultimate in 2D localization. With 120 channels, it offers the greatest ability to capture all potential sound sources in the field of view. In addition, it allows for both near field and far field techniques with the same hardware. Two optical cameras provide excellent imaging for both nearfield acoustic holography and beamforming algorithms.
This handheld paddle features double-layered microphone channels (either 48 or 104, depending on the model) arranged in dual-channel intensity probe configurations. This allows for not only the measurement of acoustic pressure signals, but also particle velocity/acoustic intensity, making it an ideal tool for nearfield processing techniques.
One of the arrays that lives on the cutting edge of technology, the Evo AC Pro features 96 to 168 microphone channels, depending on the model. This array was specifically designed to capture the acoustics generated by aerodynamic phenomena and is the array of choice for wind tunnel applications.
