In my experience, low frequency sounds can be heard farther away. Back when we lived in Chico, CA Sierra Army Depot was a disposal site for old ordnance. They would pile it in a pit and detonate it. On a quiet day, we could faintly hear the "thump" as the sound echoed to us through the Sierra Nevada mountains.
It depends. If its a subsonic round, and you have a good suppressor, it won't be heard more an 20' away, even less in an area with lush vegetation. If its supersonic, all bets are off, and the only question is how long will the bullet remain supersonic, e.g. how long will it generate a shock wave. If you are using your weapon for home defense, you don't need supersonic ammo.
