Title: Tackling NVH ONE dB PER DAY
text: New tools and technologies are helping engineers reduce vehicle Noise, Vibration and Harshness. The vehicle chief engineer did not like what he was hearing on this recent evaluation ride. He was reviewing a new transmission scheduled for production in his company's iconic sporty car. But the marriage of transmission and platform was generating unacceptably high cabin-noise levels. The CE wasn't pleased. His design and manufacturing engineers explained that the new gearbox featured a thin-wall aluminum case for reduced mass. However, the lightweight case was the noise transmitter.
