Acoustic Engineering

New powertrain concepts, powertrain downsizing driven by C02 reduction and the trend towards hybridization and electrification of vehicles lead to new and challenging demands for acoustic engineering and NVH refinement.

Sound quality, sound branding and legislative pass-by noise regulations are big factors in AVL's customer projects for two-wheelers.
Noise, vibration and harshness (NVH) are very important topics in the development of a new tractor vehicle. Legislative requirements for operator ear level, the comparison to competitor vehicles in terms of noise and vibration as well as sound quality set very challenging targets. NVH optimization of complete vehicles in conjunction with trade-off discussions between NVH, costs, emissions and durability is one of the most challenging tasks in the vehicle development process.
Hybrid vehicles add much complexity to powertrain and vehicle development. From an NVH point of view especially the sound consistency in the vehicle interior and the transition between different propulsion systems is of high interest. Additionally legislative regulations for minimum exterior noise have to be considered in hybrid vehicle developments.
Powertrain development and in-vehicle integration necessarily include plenty of NVH development. Based on our more than 40 years of experience we support our worldwide customers in their developments by simulation and experimental acoustic development. In the case of remaining NVH topics, we also provide solutions and a second opinion for powertrain and vehicle NVH refinements.
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.
Noise Vibration and Harshness (NVH) are very important topics in the development of new construction equipment. Legislative requirements for operator's ear level as well as the comparison to competitor equipment in terms of noise and vibration as well as sound quality set very challenging targets. NVH optimization of complete vehicles in conjunction with trade-off discussions between NVH, costs, emissions and durability is one of the most challenging tasks in the development process.
The experience of drivers and passengers in electric vehicles is quite different from current IC engine driven vehicles. As the masking noise of the IC engine is missing, more attention is placed on other noise sources like fans, pumps and power electronics. Additionally, new legislative regulations for the minimum exterior sound of electric vehicles opens up new fields for NVH development.
