In the case of an unavoidable collision throws the future Mercedes E-Class just for the impact a static noise of 85 decibels on the speakers. That is hard, but not so hard that your ears its damage. By doing this in your middle ear is a muscle attracted in a kind of acoustic reflex. This ensures that your ears are better able to deal with the bang that follows.

It helps you not to make a mistake to avoid, but it helps with physical damage in case of an accident. A kind of geluidsairbag, so to speak. Although there is still little scientific research that demonstrates that it works, according to specialists very likely that the system hearing damage helps to reduce or even prevent.
