NVH

Start here, it's pretty basic. Truly understanding NVH can take years, and an education. You cannot be injected with knowledge.

Noise, vibration, and harshness - Wikipedia, the free encyclopedia

Automobile manufacturers fight NVH all the time. Factories design it out before the cars hit production. But when there is an error in production, the dealers are stuck finding the cure. It could be a missing part, an extra part, or just a poor assembly job.

Try talking to a service manager at a local new car dealer. If more information is required, contact a zone manager for a manufacturer.
