According to my dad it doesn't go away. When I got old enough to go out places with my friends and come home later at night (past 11, for example) my dad said it took a couple years before he could fall asleep without hearing the garage door open, and he's a deep sleeper who's never had any issues sleeping anywhere. We've joked he's going to miss his own funeral because he's slept in.
