Tools for noise source localisation
This set of tools allows identifying noise sources in mecha(tro)nic systems or industrial installations.
Location: FlandersMake@KULeuven
Description
With this set of tools we can identify noise sources in mecha(tro)nic systems or industrial installations. Our infrastructure consists of an acoustic camera with 40 microphones and various one- and three-dimensional sound intensity probes, allowing us to visualise radiated noise in up to three dimensions. After characterisation of the dominant noise sources, we can also offer appropriate countermeasures to efficiently reduce the noise issue.
