AVL NVH test systems are designed to achieve ultra-low background noise levels for highest signal and noise ratios. Seamlessly integrated test bed automation, data acquisition and simulation tools that help to reduce development time significantly. ...
Acoustics Simulation Levels Full-vehicle level Noise generated by the full car in motion. System level Noise coming from machines working together. Sub-system level Noise coming from a specific machine, such as an e-motor. Component level Noise generation from an individual element, such as a ...
NVH stands for Noise, Vibrations & Harshness – particularly in the context of automobiles, especially passenger vehicles. Occupants of a moving vehicle often experience noise, vibrations & harshness, or NVH. NVH is very unpleasant at varying motor speeds and also causes fatigue on both the vehicle...
NVH parameters which consist of noise (unwanted sound), vibration (mechanical oscillation) and harshness (severity or discomfort of noise or vibration) need to be evaluated in order to improve comfort and safety levels for vehicle occupants. In this paper, NVH study was conducted on Malaysian ...
“Ferrari has developed hybrid technology,” says Francesco, “it combines internal combustion and an electric engine and is currently in production. We always have to produce better cars, better performance, and that special sound." Adopting a Brüel & Kjær NVH Simulator, Ferrari aims to dev...
