Sound source localization is an important topic in the working field of sound & vibration, from the product development stage till the end off line quality control of products. Scan&Paint 3D is an innovative solution allowing the localisation of sound sources completely in 3D! In a matter of minutes the complete sound field, as 3D sound vectors, is displayed on a 3D model over a broad frequency range and with an unparalleled dynamic range.

The Scan & Paint 3D is a new fast tool to visualize stationary sound fields in a broad frequency range. The system is a superb engineering tool for troubleshooting or benchmarking all type of object on the spot. In practice, there are many cases where anechoic conditions are not applicable, for instance in an industrial manufacturing environment, an engine bay or car interior. Microflown probes are not highly  affected by background noise or reflections and are suitable in situations with a high sound pressure over sound intensity ratio. Microflown probes allow direct measurement of sound pressure, particle velocity, sound intensity, sound power and the acoustic impedance. Measuring the complete sound field has never been more easy and accurate as with the new Scan & Paint 3D.

The sensor, its orientation and position is fully tracked in 3D.The opticaltracking system is based on monitoring a defined measurement space using astereo camera. Each camera is equipped with an infrared (IR) pass filter in frontof the lens, and a ring of IR LEDs around the lens to periodically illuminate themeasurement space with IR light. This light is not visible to the human eye andits intensity is completely safe for human beings to work with. The sensor isequipped spherical marker, with embedded retro-reflective markers, whichreflect the incoming IR light. The IR light reflections are detected by the stereocamera, and the tracking system translates them to exact 3D coordinates alongwith the sensor orientation.

The state of the art sensor is the so called USP. The three dimensional ½ inchUSP regular probe consists of three orthogonally placed Microflown acousticparticle velocity sensors and a sound pressure microphone. The actual sensorconfiguration without its cap is less than 5×5×5mm! Any sound field isdescribed by two complementary acoustic quantities, the scalar value 'soundpressure' and the vector value 'particle velocity'. The Microflown is the onlysensor that can measure the acoustic particle velocity directly. Thanks to theunique properties of the USP probe all physical quantities, sound pressure andtri-axial particle velocity, can be measured directly, In order to get the 3DSound intensity vectors without any frequency limitations.

All results can be visualised on an interactive 3D model. This model can be easily created with the 3D Shape Editor. 3D models can also be importedfrom a veriety of supported files formats e.g CAD, SkechUp.
