LMS International debuted LMS SoundBrush, its new and patented acoustic troubleshooting solution. LMS SoundBrush is a tool that enables engineers to map sound propagation around an object and localize acoustic sources. LMS SoundBrush makes sound visible. It is the first technology ever to visualize sound fields in 3D while measuring. At the heart of the compact SoundBrush solution is the patented optical tracking technology, combined with either a G.R.A.S. Sound & Vibration sound pressure microphone or a 3D intensity sensor.
