HEAD VISOR hardware – Microphone arrays for localizing sound sources using beamforming technology
The HEAD VISOR measurement system comprises the software and a microphone array. The acoustic camera uses beamforming technology to pinpoint sound sources in real time. Various microphone arrays are available for different applications. Some are scalable and customizable and all can be activated and controlled with HEAD VISOR software.
As soon as the microphone array is switched on, HEAD VISOR software provides video images with simultaneously overlaid, high-quality source mapping. This feature allows you to obtain the necessary information about the sound source without any time delay.
All three hardware versions combine beamforming with MultipleEye technology, using three cameras to record the video images in real time. This process enables distances to all points in the image to be determined with exceptional precision and allows continuous, synchronous video images in real time.
