The HEAD VISOR VMA V Acoustic Camera is a handheld unit that can be used for troubleshooting, leak detection and visualizing acoustic weak points. It can be applied on test benches, in wind tunnels, or for environmental measurements, HEAD said.

The camera comes with its own proprietary software, HEAD VISOR 6, which combines functions such as recording, playback, analysis, and reporting, and which also features unique artificial intelligence algorithms (like neural deconvolution) to increase dynamics and spatial resolution.

According to HEAD, the camera features a seven-inch multi-touch display and four control buttons “that enable instant and highly precise results.”

The camera’s 30-cm-body features a depth camera for distance measurement and 60 microphones for close-up applications. The device is also easily extendable with ten spiral arms, adding another 60 microphones and creating a one-meter diameter array.

“With this array, HEAD VISOR VMA V achieves a higher resolution and makes sounds visible down to a frequency of typically 250 Hz,” HEAD noted. “HEAD VISOR VMA V allows users to visualize sounds at a wide range of distances, starting from only 30 cm.”

Users can select between four license models that range from letting users take a snapshot of the object under investigation and export it instantly, to a full license that grants access to the full range of features the system offers.
