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. When moving the SoundBrush probe freely around the test object in any orientation or position, the sound field is immediately visualized on screen in 3D.

Plug and play connections ensure that no time is lost setting up the system, nor is there is any need for calibration or post processing of data. Supplied with real-time yet detailed results, users can fully focus on their core task: solving the acoustic problem.

Key to accurate and real-time acoustic troubleshooting with LMS SoundBrush is its refined software. The intuitive software supports logic handling, from setup to reporting, and offers unmatched visualization of results in 3D. The software visualizes the 3D sound field in real time while measuring. As such, it allows for a quick and accurate interpretation of the measured data. Using LMS SoundBrush, engineers can visually communicate results with colleagues, management and customers.

”Acoustic troubleshooting is a challenging yet essential process in many industries. LMS SoundBrush brings a new dimension to this process,” commented Bruno Massa, Vice President of the LMS Test Division.” The SoundBrush is a unique tool for accurate, fast and intuitive acoustic troubleshooting and source localization. What sets it apart from other applications is the automatic position detection and the real-time visualization of the 3D sound field. This provides detailed, on-the-spot results for easy identification of noise sources.”
