Vehicle Safety| Per Lewerenz | Nov 2019 21 PRE-SAFE® Sound
Preventive pre-conditioning of the occupants • Idea: reduce the effects of noise stress caused by 3 collisions • Function: If the car detects certain critical situations, the sound system emits a short pink noise signal 2 1 4 Reflex mechanism • Pink noise pattern is able to make the stapedius muscle contract • Protective effect: reduced noise effect on the inner ear
