Acoustic Camera Sphere 80 AC Pro-1

Acoustic Camera Array Sphere80 AC Pro80 Channel System for Acoustic Measurements in 2D and 3D The spherical 80 channel microphone array is primarily designed for 360° sound source localization. The light carbon fiber structure ensures easy handling as well as fast and precise array positioning. The omnidirectional microphone positioning of the Sphere80 is particularly well-suited for sound source localization in enclosed spaces. Due to its acoustically transparent design, accurate measurements are carried out without influencing the sound field. In combination with the Noiselmage software, sound sources can be isolated, localized, and analyzed with respect to both frequency and time response. Additionally, this acoustic measurement system enables the determination of a three-dimensional acoustic map. Because of the high number of microphone channels, the low noise suppression starts at 9 dB (acoustic mapping). ■ Easy handling and accurate microphone positioning ■ Three-dimensional acoustic analysis ■ Sound source localization in all directions ■ Acoustically transparent array design ■ Highest spatial resolution while providing high depth of field ■ Mapping onto 3D model ensures accurate focus distance for complex structures ■ Room & building acoustics ■ Performance venue measurements The array comes with an integrated Intel® RealSense™ Depth Camera which features Full HD resolution and the ability to record depth information.
