Interference Images: Noise-Emission of a Car

View into the motor room

Let's observe now 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! Note also the week reflexion at the front-compartment.
