LMS started with a vision: What if a device could materialize the sound field around an object? Thinking out of the box, results were achieved that was unimaginable before. This is what makes SoundBrush a very inspiring product that lets you dream about inventive engineering applications.

LMS recently unveiled this breakthrough innovation that transforms our conception of acoustic imagery. SoundBrush is a revolutionary, easy-to-use and complete tool that maps sound propagation around an object and immediately localizes the acoustic sources.

Revolutionizing the techniques of acoustic imagery by making sound visible, it allows visualization of sound fields around an object in real-time 3D. The test setup is extremely simple. Take the probe in your hand and just “brush” it around the tested object in any desired direction or location. You will immediately see on your PC, a 3-dimensional representation of the sound field around the object, including sound intensity values and sound propagation directions.

Packed with advanced technologies, it ensures fast, accurate and clear results. The best part is that this technology is entirely hidden in the small probe. A patented, optical tracking technology combined with a top-class sound pressure microphone or 3D intensity sensor from our partner G.R.A.S. makes this device work.

The graphical display is so intuitive that you can interpret it without deep knowledge of acoustic engineering. And for the specialists, SoundBrush offers new perspectives in sound engineering, very complementary to traditional sound source localization techniques like beamforming or holography.

As a multipurpose tool, it can be used to analyze any type of object. It is useful for applications where traditional sound intensity measurement methods fail. Successful performance tests were conducted on cars to detect door seal leaks and on tumble dryers to spot acoustic defects of the enclosure.

Another advantage is that it is incredibly fast and intuitive. The beauty of this device is that as you discover acoustic hotspots in real time, you can immediately concentrate your measurement on the hotspot, without having to re-set the test. The full 3-D view helps you know where to focus your attention and then further brush on the hotspot in any desired position or orientation. The 3-D view also gives unique insight into actual sound propagation.

SoundBrush offers endless possibilities, such as virtually tracing the path of a sound wave from its source to a receiver. Take it in your hand and explore new ways to look at sound sources and propagation with unequalled ease of use.
