Acoustic Engineering for Heavy Duty On-Road Vehicles

The AVL Acoustic Engineering team supports our customers and provides the latest NVH development tools and methodologies, NVH facilities and engineering capabilities to develop individual solutions for and together with our customer.
 


AVL Approach

The major services of AVL's focus on NVH development are:

  • Engine and Powertrain NVH Development
  • Vehicle NVH Refinement
  • NVH Powertrain Integration
  • Vehicle and Powertrain NVH Simulation
  • Sound Engineering
  • NVH Software and Methodology Development

The excellent know-how and innovative ideas, as well as the strong link of the NVH team to other skill teams within AVL, ensures the successful outcome for each and every individual project and generates an additional benefit for our customers.

In order to support our engineers during NVH development, AVL has developed specialized NVH tools. These tools are designed and implemented under the lead of acoustic engineers to meet the engineer's needs. Please find a detailed description of our tools in the "Acoustic Engineering Tools" section.


Customer Benefits

Based on more than 40 years of experience and our ongoing R&D effort to improve processes, analysis methodologies and refinements, we provide the following services to our customers:
