Effect of a Car Engine Compartment
Nach oben
In this example the diesel knocking (idle) in the engine compartment of a car is recorded with HEAD VISOR. In order to evaluate the effect of the engine cover, one recording is made with the engine cover and one without it. In direct comparison the difference is immediately audible and visible. Furthermore it can be seen that the engine emits sound especially through the front left corner. This area, however, is not masked by the engine cover. In this example a sound optimization can not be realized by designing a thicker engine cover but by enlarging it to the front.
