Noise Vibration Harshness and Interior Acoustics
NVH & Interior Acoustics Simulation
Our NVH (Noise, Vibration, Harshness) and interior acoustics simulation approach provides a comprehensive understanding of noise propagation from source to receiver. It enables detailed insight into structure-borne noise transmission, structural-acoustic coupling, and in-cabin acoustic response under realistic operating conditions.
Problem Description - From Source to Receiver
In the automotive domain, structure-borne noise follows a complex transmission path:
Road surface ► Tyres ► Chassis ► Mounting Points ► Body Panels ► Acoustic Cavity ► Cabin (Microphone/Passenger position)
Understanding each stage of this chain is essential for effective noise reduction and NVH optimization.
We develop high-fidelity simulation models covering all relevant physical domains:
Structure Domain
- Tyres
- Chassis
- Body-in-White (BIW)
- Full vehicle body with trims
Poro-Elastic Domain
- Acoustic absorbing materials
- Trim components and insulation layers
Air Cavity
- Interior cabin acoustic volume
- Coupling between structure and enclosed air
Results & Analyses
We provide detailed analyses to identify, quantify, and optimize noise behavior:
- Local Dynamic Stiffness (LDS)
- Noise Transfer Function (NTF)
- Acoustic pressure distribution
- Panel contribution analysis
- Transfer Path Analysis (TPA)
