Noise testing (NVH)
Every sound has a cause. We find it.
What is it about?
The method in one sentence.
NVH stands for Noise, Vibration, Harshness – the scientific assessment of noise and vibration behavior of technical parts. RTE measures airborne and structure-borne sound on motors, transmissions, pumps, actuators and comfort components – objectively, reproducibly and in real time.
How does it work?
Sensors (microphones, accelerometers, laser vibrometers) capture sound or vibration. SonicTC decomposes the signal into frequency components (FFT), analyzes orders and psychoacoustic metrics, and compares the result against test specs or a trained AI model.
Typical applications
- EOL noise testing on e-drives and combustion engines
- Comfort acoustics on seat adjusters and lifting systems
- Pump testing on water, fuel and hydraulic pumps
- Transmission diagnosis with order tracking
- Psychoacoustic evaluation of consumer goods
