FEV has over 35 years of experience conducting industrial and scientific NVH projects worldwide and employs more than 100 highly qualified NVH specialists. We have a solid reputation as a reliable engineering partner to OEM’s and automotive suppliers. Our partnership with universities and our continuous involvement in industrial and public research projects ensures that our methodologies are always up to date and thorough. The high quality standard of our work is guaranteed by modern testing equipment and facilities combined with cutting-edge NVH simulation tools and methods.

NVH services

from concept to Start-of-Production

Excellent NVH has become a vital vehicle development target as it contributes to product quality, driving pleasure and customer satisfaction. Advanced NVH experimental and virtual tools are prerequisites for cost and time effective development minimizing pre-production troubleshooting effort and shortening time-to-market. Our scope of work ranges from NVH benchmark and target setting, troubleshooting, sound design, low noise powertrain and driveline development, NVH engineering within vehicle integration up to full vehicle NVH development responsibility. Besides passenger cars the field of our NVH activities covers also trucks as well as off-road and industrial machinery. FEV’s NVH expertise includes:

  • Engine and transmission NVH
  • Body acoustics
  • Aeroacoustics
  • Power train induced NVH
  • Road NVH
  • Sound Package
  • Legal (Pass-by and interior noise)
  • Sound design and sound quality
  • Squeak and Rattle
  • Component induced NVH

Key methodologies

for excellent NVH development

FEV’s strength is the holistic understanding of both, the power train and the vehicle. Our successful and reliable NVH development is based upon the deep knowledge of noise sources and the corresponding transfer paths, proven in a multitude projects for our worldwide customers. The challenge for the NVH specialists is to support the concept and design development process by reliable recommendations just-in-time prior concept or design freeze. Therefore - besides commercial CAx development tools - FEV’s specialists particularly use in-house methodologies for NVH simulation and optimization:

  • Powertrain Structural Optimization based on Finite Element Calculation (FEV-DIRA)
  • Optimization of Engine Dynamics based on Multi-Body-Simulation (FEV-Virtual Engine)
  • Combustion Noise Optimization (FEV-CSL/FEV-CSL CAL)
  • Vehicle Interior Noise Simulation (FEV-VINS)
  • Vehicle Interior Noise Simulation based on measurement and CAE (FEV-V-VINS)
  • Vehicle Interior Noise Simulation with focus on chassis dynamics (FEV-C-VINS)
  • Vehicle Exterior Noise Simulation (FEV-VENS)
  • Objective Analysis of Sound Quality (FEV-SQO)
