Acoustic quality assurance with artificial intelligence

Fraunhofer IDMT will be presenting a new solution for contact-free acoustic quality inspection at the Sensor+Test, the leading trade fair for measuring and testing technology in Nürnberg.
 

The Fraunhofer researchers will be showcasing interactive demonstrators for optimizing existing testing methods with the help of acoustic condition monitoring of objects. The method developed by Fraunhofer IDMT combines audio signal processing and machine learning algorithms.
 
One of the demonstrators will be illustrating how the noise produced by different motors can be measured and analyzed in order to detect out whether a motor runs flawlessly or whether it is defective (or likely to become defective due to motor overload). The second exhibit of the Fraunhofer IDMT is more playful. While indulging in a game of air hockey, visitors will be shown how different pucks – which look and sound pretty much the same to the human eye and ear – can be distinguished in real time by the sound they produce during the game.
