Acoustic Engineering for Compact Engines and Two-Wheelers

Sound quality, sound branding and legislative pass-by noise regulations are big factors in AVL's customer projects for two-wheelers.

AVL Approach

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 customers. The major services of AVL focusing on NVH development are:
  • Engine and Powertrain NVH Development
  • Sound Engineering
  • NVH Software and Methodology Development
  • Pass-by noise development to meet legislative regulations
  • Sound branding
The excellent know-how and innovative ideas as well as the strong link of the NVH team to other skill teams within AVL, enables a successful outcome to each and every project and generates an additional benefit for our customers.
 
In order to support our engineers during NVH development, AVL have developed specialized NVH tools. These tools are designed and implemented under 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 our more than 40 years of experience in conventional powertrain development and our ongoing R&D effort to improve processes, analysis methodologies and refinements we provide the following benefits to our customers:
 

Your Benefits

  • Confidence and reliability through production-feasible, cost-effective and proven NVH solutions
  • AVL's in-house research and strong involvement in national and EU research projects supports a view beyond technology horizons
  • One experienced partner for NVH simulation and experimental acoustic development
  • Know-how transfer to your resident engineers
  • Complete confidentiality for all our projects

  • Close cooperation through manifold AVL engineering centres worldwide with on-site support of highly qualified staff
  • Project work in close cooperation between OEM's, AVL and sub-suppliers as well as integration of project work in the OEM development process
  • Customized work packages for every scope – from small troubleshooting to large scale projects, from concept up to SOP
  • The unique competence synergies of AVL's three business areas Advanced Simulation Technologies, Powertrain Engineering and Instrumentation and Test Systems is the basis  for each NVH project
 

References

Satisfied customers are the best evidence for successful projects and developments. The AVL acoustic engineering team has performed customer projects as well as research projects for more than 40 years. Due to confidentiality reasons the published references for our work are limited – but this is also part of our sustainable success.
