Just because it's not been mentioned in the other comments thus far: Car crashes are loud. And it's worse if you don't see it coming (so that you could "prepare" your ears).
Yeah, totally blind sided by it, so I never saw it coming. Someone tried to pass me on the left while I was turning left with my turn signal on (it was still flashing after the fact according to the police report). It was a 2 lane FM road in a double solid line. I also had a side impact airbag that deployed, so no telling how loud that was as well. Thankful for it, as it prevented all of the shattered glass from flying into the car and my face.
