The Perfectly Silent Car - An Engineering Goal? 2001-01-0048
A look at the car development of today shows that even strictly cost oriented cars try to give their customers comfort and calm riding. High value cars explain themselves as a substitution for your home when you are on the road.
Even from the environmental point of view, people, governments and many associations claim for more reduction of the noise emitted by vehicles. So can it be really a question that the main scope of engineering should be the development of cars as silent as possible?
Noise or sound is something that is present even if it seems to be silent. Information are exchanged and emotions controlled. The answer to the above question is not only a technical one but also is touched by marketing and political issues.
On the way through the global vehicle noise vibration and harshness (NVH) the following lecture shows that sound design and engineering, acoustic quality, customers expectations and noise legislation are the important areas to define the noise behavior of a car.
