Acoustic Camera Array Sphere48 AC Pro48 Channel System for Acoustic Measurements in 2D and 3D The spherical 48 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, even under rough conditions. The omnidirectional microphone positioning of the Sphere48 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. ■ Lightweight array-body ensures easy handling and accurate microphone positioning ■ Easy set up in vehicles for measurements while driving ■ Three-dimensional acoustic analysis ■ Sound source localization in all directions ■ Acoustically transparent array design ■ Mapping onto 3D model ensures accurate focus distance for complex structures ■ Vehicle interiors (e.g. car, train, airplane) ■ Buzz, squeak and rattle ■ Room & building acoustics The array comes with an integrated Intel® RealSense™ Depth Camera which features Full HD resolution and the ability to record depth information.
