Supporting OEMs, Suppliers, and Engineering Teams Across the Development Cycle
At Mecanum, we provide advanced Noise, Vibration, and Harshness (NVH) solutions tailored to the aerospace industry. From reducing cabin interior noise and designing aircraft engine liners to developing payload soundproofing treatments, our experts and tools help aerospace manufacturers, suppliers, and engineering teams create custom NVH solutions that meet the highest performance and safety standards.
From Material Characterization to System-Level NVH Modeling
https://mecanum.com/measuring-instruments/high-flow-resistance-meter/We support aerospace NVH development at multiple levels—from base acoustic material properties to full-aircraft vibro-acoustic modeling.
Our capabilities include:
• Acoustic material characterization labs, with dedicated instruments aircraft engine liners design and validation as our high-level impedance tubes, grazing incidence tubes or our high flow resistance meter.
• NOVA for simulation and design of multilayer acoustic packages, including elastic, viscoelastic, porous components, perforated plates, and Helmholtz-based metamaterials.
• VA-One integration for complete system-level vibro-acoustic simulation.
• AcoustaLink, a collaborative database to manage and share material properties across teams.
These solutions support accurate, efficient NVH design from early material testing to final aerospace system validation.
Material Characterization and Measurement Capabilities
Accurate input data is critical for reliable aerospace NVH simulations and performance predictions.
Our laboratories provide:
• Full characterization of JCAL and Biot properties for aerospace acoustic materials.
• Specialized high-level and high-frequency impedance tubes and high-flow resistance meters, developed for acoustic treatments in high-sound-level aerospace applications.
• Oberst Beam system for precise damping material characterization across wide frequency and temperature ranges—essential for structural integrity and durability in demanding aerospace conditions.
Work with Mecanum for material characterization services or build your own aerospace 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 for supplier details, pricing, or durability metrics.
• Filtering and material comparison based on performance and cost.
• Seamless integration of lab results, simulation inputs, and supplier specifications.
With AcoustaLink, aerospace teams achieve traceability, consistency, and efficiency in NVH data management.
NOVA: Acoustic Package Design and Simulation
NOVA is a powerful tool for designing and simulating multilayer aerospace acoustic treatments using transfer matrix methods. It supports both component-level and subsystem-level acoustic modeling.
Applications include:
• Optimization of complex multilayer systems (elastic, viscoelastic, porous, or hybrid acoustic layers).
• Simulation of advanced materials, from micro-macro formulations to wave-number approaches for composites.
• Results sharing with Auralization tools, enabling engineers to hear treatment effectiveness and obtain single-number ratings (STC, Rw, NRC, SAA, Aw).
NOVA offers the flexibility aerospace engineers need to design custom NVH treatments for cabin comfort and payload protection.
VA-One Integration: Aerospace Vibro-Acoustic Simulation
VA-One combines FEM, BEM, and SEA methods to perform system-level acoustic simulations across broad frequency ranges. Integrated with NOVA, it delivers a complete aerospace NVH workflow.
Use cases include:
• Cabin noise analysis under aerodynamic or vibro-acoustic excitation.
• Engine liner and sound package evaluation.
• Transfer path analysis (TPA) for identifying and controlling dominant NVH sources.
• Aerodynamic noise simulations through coupling with CFD tools (e.g., OpenFOAM).
With VA-One, aerospace manufacturers can evaluate design changes virtually, reducing reliance on costly prototypes and test flights.
From simulations to real-world validation
Mecanum’s team has strong, proven experience in checking that simulations match what happens in reality.
This includes comparing predicted cabin noise with microphone array measurements, verifying vibration models using shaker or modal tests, and confirming transmission-loss predictions for panels and composite structures under realistic conditions.
These validation steps ensure every simulation delivers accurate results for real world applications.
Quality Control and Supplier Validation
Mecanum also supports aerospace 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 tools are essential for benchmarking, supplier audits, and certification compliance in aerospace NVH processes.
