The laws of physics make it such that lots of variables change sound level readings - air density (so temperature, too), physical surroundings, and others - so it is impossible to say what kind of actual readings your car will register.

Heck, it isn't even likely that the same readings will result at the same track on different days. Remember too, louder isn't necessarily faster.

Edit - and noise contributes pretty dramatically to driver fatigue, FWIW.
