Acoustic Compass - acoustic 3D intensity probe

3D acoustic intensity probe - Acoustic Compass acoustic camera for low frequencies

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.
