Acoustic test technology on a scientific foundation.
From the Fraunhofer Institute to series production – we have been developing test methods that make quality audible since 1998.
How acoustic testing works.
Every part has an acoustic fingerprint.
Acoustic test technology uses sounds and vibrations as information carriers. Defects, wear or material deviations measurably alter this fingerprint.
SonicTC analyses these changes – objectively, reproducibly and fast enough for series production. The result: a digital test record per part, in under a second.
- Eigenfrequency and modal resonance reveal cracks, structural defects and material mix-ups.
- FFT, order and envelope analysis characterise noise anomalies.
- Time-domain vibration monitoring detects tool wear and joining errors in real time.
Three disciplines, one platform.
Noise testing
Objective evaluation of airborne and structure-borne noise – on motors, gearboxes, pumps and actuators. Psychoacoustics, order analysis, golden-part comparison.
Material resonance analysis
Eigenfrequency, Q-factor, damping and mode shifts detect cracks, voids and material defects – non-destructively and fully automated.
Process monitoring
Real-time vibration analysis for tool wear, joining and machine monitoring. PROFINET-ready, Industry 4.0.
Fraunhofer at the core.
Spin-off of the Fraunhofer Institute.
RTE was founded as a Fraunhofer spin-off. This origin still shapes our work. Every analysis method in SonicTC has scientific roots.
Each year we invest a significant share of revenue in R&D – for methods that will be tomorrow's standard.
- Active participation in EU and BMBF research projects on non-destructive testing.
- Cooperation with Fraunhofer IZFP and other research institutes.
- Own acoustic lab with low-reflection environment in Pfinztal.
Certified test technology.
Quality management
ISO 9001 certified QM system – covering engineering, production and service.
Measurement system analysis
Cg, Cgk, Gage R&R, Cm/Cmk, Cp/Cpk – integral to every SonicTC commissioning.
Traceable
Hardware and sensor calibrations traceable to national standards (DAkkS).
With SonicTC we made the jump from sampling to 100% inline testing – without replacing our existing hardware.
