@meetmargin: Car crashes and airbag deployments can reach 145 to 165 decibels—loud enough to cause permanent hearing damage. To protect your ears, Mercedes-Benz developed PRE-SAFE Sound. ​When onboard radar detects an unavoidable collision, the sound system emits a burst of 80 dB "pink noise" milliseconds before impact. This harmless frequency pre-triggers your ear's natural stapedius reflex—stiffening the tiny bones behind your eardrum before the deafening bang hits. Combined with seatbelt pre-tensioning and side-bolster inflation that pushes you away from the door, the car physically braces both your body and your ears before you even realize what's happening.#MercedesBenz #CarSafety #AutomotiveEngineering #TechExplained #engineering
