How The New Mercedes-Benz E-Class Will Protect Your Ears In A Crash

It takes just a split second for a car accident to completely change a person’s life. Mercedes-Benz PRE-SAFE® can help to minimize the damage. Once the vehicle’s sensors have detected that a collision is unavoidable, a comprehensive system of safety features are activated within the short time that remains before the impact occurs.

“It kicks in before the collision occurs, preparing the vehicle and its occupants. PRE-SAFE is therefore one of our systems that is based on what actually happens in real-life accidents and helps to save people’s lives.”

The system is the first to harness a natural reflex to condition the ear – when a collision is imminent – for the loud noise that is anticipated from the impact. If an impending collision is detected that would be expected to produce a loud crash, the vehicle’s sound system plays a short interference signal. This causes the stapedius muscle in the ears to contract, which for a split second changes the link between the eardrum and the inner ear and so better protects it against high acoustic pressures. Most importantly, the reflex reduces the damage to hearing.
