Highly Efficient Sound Power and Sound Intensity Measurements with Augmented Reality
HEAD acoustics has announced a new award-winning Augmented Reality solution from HoloMetrix. The ArtemiS SUITE Sound Intensity Module ASM 30, allows users to measure sound intensities to determine sound power according to ISO 9614 or create sound intensity maps for quick source localization.
The company says that the software's assistance functions guide even inexperienced users safely through the necessary steps. For example, if a procedure standard requires a measurement grid surrounding the test object, actual physical setups at a high cost have been necessary, making the measurements very time-consuming and complicated. This is often an exclusion criterion, especially for troubleshooters who need to achieve results quickly.
The HoloMetrix solution projects a virtual measurement grid onto the screen of the AR glasses and thus overlays the real test object and the measurement probe, whose orientation is based on the measurement grid. In addition, it overlays the sound power of the already measured partial surfaces in color, making acoustic measurements intuitive and time-efficient. The standard-compliant measurement positions are automatically visualized on the AR glasses and no longer have to be determined by the users in a time-consuming manual process. Together with HoloMetrix, HEAD acoustics has developed an interface to the ArtemiS SUITE software. Combined with ArtemiS SUITE, Augmented Reality significantly reduces the setup effort and offers several additional synergy effects. For example, users first configure the test setup in ArtemiS SUITE and transfer it to the AR glasses with one click.
The innovative Frankfurt-based startup HoloMetrix GmbH has developed a software platform for acoustic measurements based on Augmented Reality, which projects the virtual measurement grid in three dimensions in the actual measurement environment. HoloMetrix was honored for this positioning support on May 24, 2022, in Berlin in the presence of HoloMetrix Managing Director Alexander Pfaff and Dr.-Ing. Aulis Telle, Technical Managing Director Sound, Vibration and Perception at HEAD acoustics, with the golden German Innovation Award from the German Design Council in the "Excellence in Business to Business" competition class in the "Machines & Engineering" area. The award honors companies that impress with new, forward-looking technologies, processes, or services.
