I've heard sonic booms from aircrafts and those are pretty much loder than from a small rock. The background noise level here is other than that of a quiet countryside. Two highways and a major airport (Copenhagen) just a fe tens of kilometers away. There are allways rumbling in the air... ;) I don't think anyone could hear a sonic boom from here unless it was a really big fireball. There might had been a sonic boom, but I did not hear it.
