Our handheld devices are optimized for quick sound source localization using either beamforming or nearfield methods. These devices guarantee an 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 troubleshooting because they enable real-time measurements in wide frequency ranges. Required time and effort for measurements are minimized since the lightweight device comes in a practical carry-case, already set up and ready to use.
