"Pink Noise" ... never heard of
Mercedes Benz is busy with protecting the ear during a car crash. It seems that a car crash can produce noise in a car reaching 145 decibels, the popping out of the air bag 165 decibels.
They create a pre-safe sound of 80 decibels containing pink noise. And this will protect the ear.
Pfffff, very tiresom on a friday evening.
