Sensors remove the guesswork from testing engines for noise, vibration and harshness.
When consumers shell out $10,000 or more for a new car, they have little tolerance for unexpected engine noise and vibration. Trouble is, today's vehicle technology has made controlling noise, vibration and harshness (NVH) in engines more important than ever.
Advances in engine and powertrain technology, such as turbochargers, lightweight materials and complex intake systems, can make engines noisier.
