Handheld Arrays

The 2D measurement arrays from gfai tech are for use with their full Acoustic Camera System. The handheld devices are optimised for quick sound source localisation using either beamforming or nearfield methods. They guarantee easy handling for acoustic measurements in the far-field and near field.

As flexible mobile devices, handheld Microphone Arrays are a great addition to any Acoustic Camera system. Moreover, the integrated data recorder makes them usable as a stand-alone solution. Handheld arrays are especially suited for trouble-shooting because they enable real-time measurements in wide frequency ranges. Required time and effort for measurements are reduced since the lightweight device comes in a practical carry-case, already set up and ready to use.

Paddle2x52 AC Pro

52 double-layer channel system for low-frequency application
This portable handheld paddle features 104 double-layered microphone channels that allow for real-time acoustic near field measurements. The double-layer structure enables the measurement of acoustic pressure signals while particle velocity/acoustic intensity on the measurement plane is calculated and mapped simultaneously.

Paddle2x24 AC Pro

24 double-layer channel system for low-frequency application
This portable handheld paddle features 48 double-layered microphone channels that allow for real-time acoustic near field measurements. The double-layer structure enables the measurement of acoustic pressure signals while particle velocity/acoustic intensity on the measurement plane is calculated and mapped simultaneously.
