As a company, we deliver testing equipment and perform high-tech engineering of single components, powertrains, and complete propulsion systems. We find innovative and user-oriented solutions – depending on our customers’ units under test (UUT). We understand and commit to the strict acoustic standards – and aim to guarantee the commonly agreed NVH targets for the dedicated test system. All components are tuned, and the system is validated by an acceptance analysis.
With our NVH test systems for validating e-motors, we support all unit under test (UUT) variants. Our aim is to create development environments that can solve NVH development challenges quickly, efficiently, and sustainably. NVH test systems offer a range of solutions depending on the priorities of the main features, which can be summarized in three main areas across all UUTs:
• Premium setup
• Precision setup
• Efficiency setup

| Precision | This setup focuses on the on the exact alignment of micro- phones in the testbedas described in the ISO3745.The design allows for a complete microphone hemisphere without inter- ference surfaces of the mechanical setup. |
| 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. |
Highly Customizable
Standard and highly customizable testing solutions from single components to full vehicles.
Guaranteed Noise Limits
Guaranteed NVH behavior through optimal NVH design.
Minimal Footprint
Lowest acoustic impact due to minimal footprint.
Full Performance
Uncompromised power, torque, and speed performance combined with seamless integration into AVL‘s toolchain.
Premium Setup
Our premium test setup is designed for the development of ultra-silent e-motors, ensuring maximum measurement accuracy in an optimized testing environment. With an ultra-low background noise level of less than 50 dB(A), it provides outstanding signal-to-noise ratio (SNR) for reliable Class 1 measurements. The innovative decoupling concept ensures that the UUT remains completely independent of external vibrations, delivering precise and undistorted acoustic data. Additionally, the system offers full power, torque, and speed performance while seamlessly integrating into the AVL toolchain, enabling efficient development and validation processes.
Precision Setup
Our precision test system ensures full compliance with ISO 3745 by enabling an optimized microphone setup for accurate acoustic measurements. The complete microphone hemisphere allows precise detection of single-spot noise phenomena without interference from mechanical surfaces. An innovative decoupling concept ensures that the UUT remains completely independent of external vibrations, delivering reliable and undistorted results. Additionally, the system provides full power, torque, and speed performance while seamlessly integrating into the AVL toolchain for efficient testing and validation.
Efficiency Setup
The efficiency test setup enables a fast and cost-effective upgrade of existing anechoic chambers into high-performance e-motor NVH test systems. Optimized dyno enclosure design minimizes acoustic reflections, ensuring precise measurements. The flexible setup allows easy repositioning of the test system for different UUTs, including e-motors, e-axles, and powertrains. With full power, torque, and speed performance, along with seamless integration into the AVL toolchain, this solution provides the ideal balance between efficiency and NVH performance in modernized testbeds.
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.”
