In several experiments was tested, if the impulse noise of an airbag development is injuring human ear. Thought has been given to an active middle ear muscle response (called “warned exposure”). If the impulse noise stresses the passenger is particular for the left ear a hearing loss possible. If the middle ear is warned the critical limit for a possible hearing loss wasn´t reached. The possibility of an active self-protection depends from using pre-crash-sensors, because the natural protection is to slow. Further it was carried out, that the noise caused by a car-to-car-collision was in comparison to the impulse noise of an airbag development uncritical for the passenger.
