Product Overview

This scanning measuring system is a groundbreaking all-in-one box solution for solving complex acoustic problems. It is a unique tool for acoustic troubleshooting and sound source localization, allowing you to visualize what you hear. It makes complex problems simple and easy to understand. Sound source localization is an important topic in the working field of sound & vibration, from the product development stage to the end-of-line quality control. In a matter of minutes the complete sound field, as 3D sound intensity or particle velocity, is displayed on a 3D model over a broad frequency range and with an unparalleled dynamic range. The very small 3D sensor makes it possible to obtain results with a very high spatial resolution (up to 3 mm) enabling measurements even on very small objects. Localize your sound sources and visualize sound propagation in full 3D.

3D POSITION TRACKING USING AN INFRARED CAMERA

The sensor´s orientation and position are automatically tracked in 3D space. The optical tracking system is based on an infrared stereo camera. Each camera is equipped with an infrared (IR) pass filter in front of the lens, and a ring of IR LEDs around the lens to periodically illuminate the tracking sphere with IR light. The sensor is equipped with a spherical marker, consisting of embedded retro reflective stickers. The incoming IR light is reflected by the stickers. The IR light reflections are detected by the stereo camera, and the tracking system translates them to exact 3D coordinates along with the sensor orientation.

FULL 3D WRAPPED SOUND MAPPING

Accurate visual representations of measurements are now at users' fingertips with the introduction of full 3D-wrapped sound maps. Performing 3D sound localization and identifying noise issues becomes an effortless task, thanks to this feature's ability to provide an intuitive and detailed overview of sound distribution at a user-defined distance range. An enveloping layer is automatically calculated at an arbitrary distance from the object's surface, visualizing just the right data of interest.

THE REAL 3D SOUND INTENSITY PROBE

The state of the art sensor used in the system is the three dimensional 1⁄2 inch USP probe. The sensor consists of three orthogonally placed Microflown acoustic particle velocity sensors and a sound pressure microphone. The sound intensity can be calculated by taking the time averaged cross spectrum of particle velocity and sound pressure. 3D Sound intensity vectors can be obtained without any frequency limitations covering a range of 20Hz to 10kHz. The small sensor size allows measurements to be taken with an unmatched spatial resolution.
