Noise-Emission of a Car

Inspecting the Engine

Let's observe the noise emission of a car. It is hard to decide, which parts of aggregates excite large quantities of noise. The front-compartment of the car is opened. We expected to see the cylinder-head and the motor. Instead of, we see something different: maximum quantities of noise come as ground reflexions from the left bottom side of the car. We remember to find cars beeing very quiet in fresh snow. Maybe, the bottom side produces the most noise. Note also the week reflexion at the front-compartment.
