As a leading provider of testing equipment and high-tech engineering services, we specialize in single components, powertrains, and complete propulsion systems. Our innovative, user-oriented solutions are tailored to the specific needs of our customers' units under test (UUT). We are committed to meeting the strict acoustic standards required in modern NVH testing, ensuring that all systems meet agreed-upon NVH targets. Each component is carefully tuned, and the entire system is validated through a comprehensive acceptance analysis, guaranteeing optimal performance.
With our advanced NVH test systems for validating e-motors, we support all UUT variants. Our goal is to provide development environments that solve NVH challenges efficiently, quickly, and sustainably.
These NVH test systems offer a range of solutions, depending on the priorities of the main features, which are categorized into three key setups across all UUTs:
- Premium setup
- Precision setup
- Efficiency setup

Premium |
This test system focuses on developing ultra-silent |
| Precision | This setup focuses on the precise alignment of microphones in the testbed, following ISO 3745 standards. The design enables a complete microphone hemisphere without interference from mechanical surfaces, ensuring accurate sound measurements. |
| Efficiency | Efficiency is a major topic in the transformation of existing testbeds. For customers who have invested in an NVH chamber and/or a component testbed, we have created our efficiency product line. The focus is on conveniently trans- forming the testbed into a solution that seeks the best com- promise between reasonable power and NVH performance. |
Premium Setup
- Highest level of measurement accuracy and wide homogeneous free-field condition thanks to optimized
test system design - Ultra-low noise level from test system to enable out-
standing SNR (signal-to-noise ratio) for guaranteed
class 1 measurement results - Fully independent vibration behavior of UUT thanks to innovative decoupling concept
- Full performance in power, torque, and speed, combined with seamless integration into the AVL toolchain
Precision Setup
- Uncompromised compliance with ISO3745 regarding microphone setup
- Precise detection of single-spot noise phenomena for the UUT thanks to availability of full microphone array
- Fully independent vibration behavior of UUT thanks to decoupling concept
- Full performance in power, torque, and speed, combined with seamless integration into the AVL toolchain
Efficiency Setup
- Easy and fast upgrade of existing anechoic chambers (e.g. engine or propulsion system testbed) to high-performance e-motor NVH test systems
- Minimized acoustic reflections due to optimized shape and surface of dyno enclosure
- Flexibility to use the NVH test chamber for different UUTs (e-motor, e-axle, powertrain) due to easy and free positioning of the test system inside
- Full performance in power, torque, and speed, combined with seamless integration into the AVL toolchain
NVH is not only about improving noise on vehicles and powertrains, much more it’s about setting up a brand sound, inspiring the passengers of modern cars during their ride. With our NVH test systems and solutions we provide a high class development platform for sound development and drive the pleasure of tomorrow’s mobility.”
