Failure detection and prevention through sound by Webasto and Noiseless Acoustics

Convertible roof systems run extensive testing programs to guarantee long-term quality which can take up to three months in continuous 24/7 operation, yet they are unable to be monitored constantly. However, possible failures need to be immediately detected and thoroughly analyzed. Together with Noiseless Acoustics, Webasto integrated the Noiseless Acoustics Sense Module into the testing fixture where the convertible roof is validated during the testing cycle. During operation, the acoustic signals of the system are recorded and bundled in the central Sense Module. The final test report outlines the correlation of incidents and predictions derived from the measured data and the hardware. The collaboration has aimed to predict failures before they happen, to save time and ensure high-quality standards.
