Data Sheet HEAD acoustics Overview HEAD VISOR flex is a modular array system for real-time sound identification and analysis. The size and shape of the array and the number of microphones can be freely and flexibly adapted to a wide range of different applications. Particularly for applications where sounds need to be localized from a great distance or with low frequencies, for example, HEAD VISOR flex systems with their large aperture and their large number of microphones are suitable, achieving a very high localization accuracy. The individual components are easy to transport and can be set up very quickly and mounted in a stable manner. In spite of its high flexibility and powerful functionality, each HEAD VISOR flex system remains an easy-to-use tool. Features Flexibly configurable microphone array system with high resolution and localization accuracy A versatile scope of application • Real-time localization of sounds, particularly with low-frequencies up to below 100 Hz or at great distances, e.g. - in a wind tunnel - in pass-by measurements - for wind power plants - for door-slamming sounds Modular design • Flexible combination of front ends, input modules, ICP free-field microphones, etc. into customized systems • Freely configurable array shape based on rugged panels, fitting every test rig • Up to several hundreds of microphones in one system • Inclusion of additional reference channels, such as artificial heads or speed sensors MultipleEye technology • Camera module with MultipleEye technology for automated measuring of the precise distance between the array and the respective sound source Powerful software • Software with an innovative handling concept, a straightforward user interface, and a wide range of functions Real-time principle • Effects of modifications, filtering, or changes of the sound sources can be monitored in real time High precision • Source mapping with a high dynamic range depending on the array shape chosen • Factory phase matching of all free-field microphones used in a system in order to minimize signal delays between microphones • Synchronization of all microphone signals by the front end with sample accuracy HEAD VISOR flex Modular array system with a large number of microphones for the HEAD VISOR system for real-time identification of sound sources Easy handling • Quick assembly and disassembly of the array • Automatic acquisition of microphone positions (no manual entry required) High safety • Mobile base frame with feet for high stability of the array • Quick and safe mounting to a wall or ceiling

• The VFC I.1 camera module provides the HEAD VISOR software with a live video image, on which a synchronized high-resolution source map is overlaid in real time. By means of the unique MultipleEye technology, images from the three calibrated cameras can be used to optically determine the distance to the objects in view. • Additional specifications: - LAN connection to PC - Triggering via the VFE II.1 front end - Retroactive offline evaluation of the data possible - including distance measurement to individual objects - Quick acquisition of the positions of all installed microphones...

Grid panel VFG I.1 Mobile chassis for grid panels VFT I.1 • The ICP free-field microphone VMF I.1 is optimized for operation in an array. The signal phases of each individual free-field microphone of a HEAD VISOR flex system are matched at the factory in order to minimize any signal delays between the microphones. The microphone socket VFM I.2 makes mounting really easy. It allows the free-field microphone to be easily snapped into any position on the grid panel and to be removed just as easily. The positions of the microphones on the VFG I.1 grid panel are determined automatically by...

Software - Overview HEAD VISOR Software By means of the unique MultipleEye technology, the beamforming is always calculated with the exact distance to the object currently in focus. The software automatically performs important functions. It is not necessary to manually start a recording. Thanks to the permanently active recording buffer (FreezeBuffer), sound events can easily be analyzed even retroactively. A rattle of the handle and the movable outside mirror during a door-slamming. The innovative HEAD VISOR software for localization of sound sources performs all important work steps in...
