What is NVH? 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 ...
In recent years, the brand has taken its commitment to elevating the in-car experience a step further through a process known as QuietTuning. This innovative approach to sound suppression focuses on minimizing noise, vibration, and harshness (NVH) in vehicles, ensuring a quieter and more relaxed...
NVH: Controlling thenoise, vibration, and harshness (NVH)levels within a vehicle is critical to passenger comfort and overall experience. By using multibody dynamics simulation, automotive engineers can identify the sources of vibration and sound emitting from all parts of a car and determine the be...

What does all of this mean in a practical sense? An air curtain helps a vehicle achieve better performance, consume less fuel, and emit fewer CO2 emissions, not to mention less noise, vibration, and harshness (NVH) experienced by the driver and occupants. In other words, the vehicle deliver...
are set early as design criteria. Although these curves may work very well to control overall NVH levels, they may not be very useful to control the final sound perception of the vehicle. In other words: How my vehicle will spark a certain emotion to the driver is not c...
The heavy cable is replaced with lightweight 2-wire CAN in today’s cars and trucks How does CAN messaging work? Devices on a CAN bus are called “nodes.” Each node consists of a CPU, CAN controller, and a transceiver, which adapts the signal levels of both data sent and received by...
The reluctance of France to accept the global war is due to the fact that() A．they are indifferent to the war. B．they cannot defeat terrorism. C．they hate the global war. D．they would pay a great deal...
I feel sort of guilty about it, since I’ve always built cars on a shoestring budget, scrimped and scrounged and (usually) settled for something less than what I really wanted because of that. This one is different. I had a conversation with a friend in Oregon who just bought a ...
6. How are torsional orders used in NVH analysis? Torsional orders aid in determining whether or not torsional vibration greatly contributes to the noise and vibration level in the product. Imagine taking data at the driver’s right ear (DRE) with a microphone. The second order data is displa...
