Versatile and Scalable, ready to take on any acoustic challenge

Our system has a proven track record of its versatility by being used in many different applications and markets. From small hearing aids to large gas turbines, size does not matter, Scan&Paint 2D has the answers. For over a decade, this versatile testing solution has been putting particle velocity on the (sound)map. The numerous product enhancements are making the tool more powerful than ever before!

An acoustic camera alternative using a single sound intensity probe

Our acoustic imaging system uses a simple and effective method for measuring time-stationary sound fields. The surface of the object being measured is scanned with a single PU probe, which is simultaneously captured by a camera. The recorded video and probe measurement data are automatically synchronized while the positions of the probe are extracted using live IR-LED tracking. This information is then used to produce acoustic imaging, which shows the origin of noise on the object. Unlike traditional acoustic camera systems, our unique probe sensing technology allows us to achieve high-resolution imaging even for low frequencies in the most challenging environments.

Real-time probe position tracking

Getting you faster to your results, that's what our new real-time tracking feature offers you. Our revamped acoustic imaging system includes state-of-the-art technology: a new generation PU probe, and a revolutionary camera. The PU Regular GEN2 has two integrated IR LEDs that are invisible to the naked eye. When used in combination with our advanced camera, these LEDs enable real-time tracking of the probe's position as it moves across the surface of the object being measured. Saving you valuable time, and allowing you to convert data into sound maps with a single click.


Capturing particle velocity directly enables testing in acoustically challenging conditions, such as office spaces, workshops, or even industrial facilities. Perform sound source localization, regardless of the size of the source or its operating environment. In addition, sound intensity becomes as straightforward as it can be, simply by taking the time-averaged cross-spectrum of the two measurable quantities, the particle velocity, and the sound pressure. Sound intensity PU probes produce broad-band sound intensity results that are not affected by the p/I index, maximizing the versatility of the acoustic imaging solution. Our advanced camera's depth technology automatically connects sound intensity to dimensions, providing direct measurements of sound power. Preserve the relative phase of the measured particle velocity distribution by adding an additional reference sensor. Sound source localization, sound intensity mapping, noise ranking, sound power, or operational deflection shapes (ODS), our versatile acoustic imaging system covers it all.
