We hear
what others
overlook.
Acoustic resonance analysis detects cracks, microstructure defects and material deviations – non-destructively in under one second, fully automated, inline. Based on 40 years of Fraunhofer research.
- Fraunhofer spin-off
- Non-destructive
- 100% inline
Every noise
has a cause.
We find it.
End-of-line noise and vibration testing for series production. Objective assessment of bearings, drives and comfort noise – in real time, within cycle time.
- Psychoacoustics
- Order analysis
- MES-ready
One platform.
Three disciplines.
Zero compromise.
One software architecture for noise, material and process. From lab trial to 100% inline series – with the same database, shared analysis and AI-driven classification.
- 4 modules
- Multi-channel sync
- AI analysis
Turnkey
into your line

Other vendors solve one problem. SonicTC solves three: noise testing, material testing and process monitoring – with one software, one UI, one database.
Noise Testing
NVH analysis for end-of-line and inline testing. Objectively evaluate airborne and structure-borne noise on motors, transmissions, pumps and actuators.

Six reasons that make the depth-difference – scientific, hardware-agnostic, from lab to line.
Science at the core.
Spin-off of the Fraunhofer Institute. Every procedure in SonicTC is based on applied research. Every year a share of revenue is reinvested in R&D.
No lock-in. Full freedom.
SonicTC works with your existing sensors – Brüel & Kjær, Polytec, PCB and many more. No vendor lock-in.
From lab to line.
The same software scales from lab bench to 100% inline. Test definitions and archives stay compatible.
AI that hears the difference.
Self-learning evaluation and anomaly detection increase discrimination. Less false-rejects, faster ramp-up.
Test before you invest.
TaaS or rental: acoustic test technology without capex risk. From idea to insight in weeks, not months.
Always reachable.
By phone, remote or on-site – worldwide. Maintenance, calibration, parameter care – optional 24/7.
How our customers deploy SonicTC.
From a Tier-1 brake manufacturer with 100% inline resonance testing to e-drive OEMs with end-of-line NVH – real examples with measurable results.
100% inline resonance testing on passenger brake discs.
Before commissioning: destructive sampling on 0.5% of parts, 14-day storage, manual evaluation. After SonicTC.AT: 100% of parts tested inline, eigenfrequency ±0.3 Hz, Q-factor and damping evaluated automatically, gapless audit trail for every part.
Your industry. Our solution.
Acoustic test technology solves different challenges in every industry. Find yours here.
Four decades of acoustic test technology.
From the Fraunhofer Institute into the production lines of leading industrial customers.
With SonicTC we made the jump from sampling to 100% inline testing – without replacing our existing hardware.
