Spherical Beamforming provides a complete omnidirectional noise map and makes no assumptions about the nature of the acoustic environment.
Bruel and Kjaer's Spherical Beamforming system makes sound mapping faster and easier in enclosed spaces like car and aircraft interiors.
Unlike other methods, which only map part of their surroundings, Spherical Beamforming provides a complete omnidirectional noise map.
It is ideal for carrying out mid-to-high frequency measurements inside vehicles, aircraft, rooms and industrial plants, as it makes no assumptions about the nature of the acoustic environment.
Measurements are taken using a spherical array, which the operator places in a typical listener's position, such as the driving seat of a car.
The array maps noise from every direction while 12 cameras, mounted on the sphere, take simultaneous pictures covering the entire field of view.
These images are then used as background display for an acoustic map.
Spherical Beamforming is one of the acoustic solutions created as part of Bruel and Kjaer's Pulse 12 measurement and analysis platform.
