Acoustic material testing
We hear Quality!
Acoustic testing technology is an environment friendly and resource-saving testing technology and therefore your investment in the future.
As a comparative testing technique, it automatically separates good and defective components from one another.
Provided that the test object can be stimulated to vibrate and the faults to be monitored have an acoustic relevance.
This often works much better than expected, especially in series testing!
SOUND OF SILENCE
There is nothing more than a slight whirring sound to be heard when an electric vehicle starts moving. Many sources of noise only come to the fore when the engine noise has almost ceased. Suddenly the air conditioning can be clearly heard, and electrically powered comfort functions emit noises that you never heard before. All of this can perhaps be "drowned out" or avoided entirely with acoustic testing technology.
RTE offers its customers clear planning approaches for the development and integration of highly automated test systems, concepts for real-time monitoring and testing or the implementation of smart testing techniques with AI algorithms.

EFFECTIVE, FLEXIBLE AND CUSTOMER-ORIENTED
An interruption to production and supply caused by breakdowns and defects in quality at the customer’s site requires immediate troubleshooting and implementation of quality assurance measures. Visual inspection alone cannot determine whether metallic components are free of cracks or structural defects. Expensive and costly CT scans give a good indication, but they are only practical for laboratory and error analysis applications. For serial monitoring, fast and efficient testing systems are required. This is where acoustic material testing offers the best possible solutions.
The present request for help was addressed with a fast and uncomplicated quality monitoring solution, thereby securing supply capabilities. One of the challenges of using acoustic material testing was the absence of defective reference parts to calibrate the system to detect defects. It was decided to initially parameterise the inspection system only for non-defective parts, in order to identify parts showing anomalous responses compared to those parts which had passed quality inspection (non-defective parts). Suspect parts were then thoroughly examined using metallurgical and CT methods. Defects were confirmed on parts exhibiting acoustical anomalies, allowing the corresponding test parameters to be configured. This validated the use of the acoustic testing technology. Reliable supply capacity and the requisite quality control were restored through the excellent teamwork of all parties involved.
