The HEAD VISOR acoustic camera measurement system comprises the software and a microphone array. The system uses beamforming technology to pinpoint sound sources in real-time. Various microphone arrays are available for different applications. Some are scalable and customizable; all can be activated and controlled with HEAD VISOR software.
When the microphone array is switched on, HEAD VISOR software provides video images with simultaneously overlaid, high-quality acoustic source mapping. This feature lets you quickly obtain the necessary information about the sound sources without delay - identify their location, sound pressure level, and spectrum.
All three hardware versions combine beamforming with MultipleEye technology, using multiple 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.
The following HEAD VISOR microphone arrays are available for the acoustic camera:
- HEAD VISOR VMA V: Lightweight, mobile, hand-held, and extendable microphone array with an integrated display and controls for the most flexible applications and results showing directly on the device (0.3 m/1.0 m diameter)
