Fraunhofer IDMT presents method for airborne-sound based quality assurance
On April 23-27, Fraunhofer Institute for Digital Media Technology IDMT will be demonstrating a method for acoustic condition monitoring and quality assurance (Fraunhofer Booth C22, Hall 2). The method allows continuous monitoring of industrial production lines as well as product quality control. It thereby helps reduce machine downtime and scrap.
Measuring and evaluating noise directly on the machine
At the Hannover Messe from April 23 – 27, 2018, Fraunhofer IDMT will demonstrate the prototype of a new cognitive system for the predictive maintenance of production facilities (Hall 2, Booth C22). Intelligent battery-powered acoustic sensors process audio signals from machines and systems on the spot. From the information that is forwarded wirelessly to an evaluation unit, it is possible to draw conclusions about the condition of the production facilities and to avoid possible damage. Industrial customers benefit from a cost-effective, scalable and data-secure Industrie 4.0 solution that minimizes downtime.
Successful presentation of the newest MEMS loudspeaker technology at this year´s DAGA-Conference
The German Fraunhofer Institutes for Digital Media Technology IDMT and Silicon Technology ISIT caused a stir at the Jahrestagung für Akustik DAGA (the annual conference of the German society for acoustics) in Munich from March 19 to 22, 2018. They presented the first integrated MEMS-based micro speakers to industry representatives and experts. The MEMS speakers will be used in future mobile communication devices, headphones, and hearing aids. With an area of just 4x4 millimeters, they cover the complete frequency range from 20 Hz to 20 kHz as a one-way system and achieve a sound pressure level of 110 dB for in-ear applications.
