Pink Noise: Pre-Safe® Sound available in the new E-Class.


If a car crash is imminent, the PRE-SAFE® Sound triggers a reflex in the Stapedius muscle, located in the ear. If the collision is likely to produce a very loud crash, a static sound is played through the car’s audio system. In physics, this sound is described as pink noise, which effectively reduces the impact on your auditory system.
