Supporting OEMs, Suppliers, and Engineering Teams Across the Development Cycle
At Mecanum, we provide advanced Noise, Vibration, and Harshness (NVH) solutions for the automotive industry. From early-stage material characterization to full system-level simulation and validation, our technologies support OEMs, tier suppliers, and engineering teams in meeting the demanding acoustic and structural performance requirements of modern vehicles, including EVs and ICE platforms.
From Material Characterization to System: Level NVH Modeling
We enable the development of effective NVH treatments at every stage—covering everything from acoustic material properties to full-vehicle vibro-acoustic models.
Our expertise includes:
• Complete acoustic material characterization laboratories with temperature dependant damping properties test bench (Oberst beam, Brake damping test following SAE J3001)
• FOAM-X for advanced property determination and simulation validation.
• NOVA for the design and simulation of complex multilayer sound packages (elastic, viscoelastic, and porous components).
• VA-One integration for complete vehicle-level vibro-acoustic simulation.
• AcoustaLink, a centralized database for managing and sharing material properties across teams.
These solutions ensure accurate data, efficient workflows, and optimized NVH performance throughout the vehicle development cycle.
Material Characterization and Measurement Capabilities
Reliable NVH design starts with precise input data. Our facilities provide state-of-the-art material characterization, including JCAL and Biot property measurements for acoustic materials.
To meet the needs of the electric vehicle (EV) industry, we have developed a high-frequency impedance tube (up to 10 kHz). We also provide adapters for testing intake and exhaust systems in internal combustion engines.
Additionally, damping plays a critical role in NVH, durability, and structural integrity. Our Oberst Beam system allows accurate damping material characterization across wide frequency and temperature ranges.
Choose between outsourcing material characterization to Mecanum or building your own in-house NVH lab with our instrumentation.
AcoustaLink: Centralized NVH Data Management
AcoustaLink is a collaborative NVH database designed to store and manage material properties, test data, and supplier information in one place. It enhances collaboration among engineers, buyers, and quality assurance teams.
Key features include:
• Direct connectivity with all Mecanum instruments and software.
• Custom data fields such as price, supplier, or durability information.
• Filtering and comparison tools for cost-performance optimization.
• Integration of lab measurements, simulation inputs, and supplier specifications.
With AcoustaLink, you can ensure traceability, consistency, and efficiency in material management.
NOVA: Multilayer NVH Design and Simulation
NOVA enables engineers to design and simulate multilayer acoustic treatments using transfer matrix methods. It supports component-level and subsystem-level acoustic modeling.
Applications include:
• Optimization of complex multilayer sound treatments (elastic, viscoelastic, or acoustic layers).
• Advanced tools for both micro-macro material formulations and wave-number simulations of composites.
• Results sharing with Auralization tools for listening to treatment efficiency, plus automatic single-number ratings (STC, Rw, NRC, SAA, Aw).
With NOVA, engineers gain flexibility and precision in designing custom acoustic packages for automotive applications.
VA-One Integration: Automotive Vibro-Acoustic Simulation
Challenge: Electric vehicles eliminate engine masking, making road noise, wind noise, and component vibrations more critical than ever.
VA One Solution:
✓ Model battery housing vibrations and composite panel acoustics
✓ Optimize cabin quiet zones and acoustic treatments
✓ Ensure AVAS (Acoustic Vehicle Alerting System) compliance
✓ Predict and control tire-road interaction noise
✓ Design effective sound packages for premium cabin comfort
Results: Meet stringent interior noise targets while maintaining lightweight design requirements essential for EV range optimization.
Quality Control and Supplier Validation
We also support production quality assurance and supplier validation through:
• Sound absorption and transmission testing in small acoustic cabins.
• Airflow resistivity measurements with robust, production-ready instruments.
These capabilities are essential for benchmarking, supplier audits, and end-of-line testing in automotive manufacturing.
