CAE - Acoustic Compass - Acoustic 3D Intensity Probe
The 3D acoustic intensity probe is for localization of sound sources from 40 Hz. The compass consists of 28 acoustic intensity probes and shows in a 3D display via 3D vectors the direction of the noise sources. Due to the small size of the acoustic 3D intensity probe and the online 3D intensity analysis it is a perfect trouble shooter.
