I remember reading somewhere that the Average db levels for a room (fans, cars driving by, etc...) is from 20-30 db.

If you get a condo with 69 STC and you add the average room db levels you get a level of 99 db.

99db is the level of loudness that you are able to play your home theatre at. without someone next door noticably hearing what you are playing.

If your home theatre is set to around 75db (like many people here) your peak explosions will be around 100db. Your neighbors should be fine and not even really notice that you are playing a movie at high levels because in their room, they already have 20 - 30 db of backround noise.

Does this make any sense?

If you get a condo with 69 STC, you are going to be able to play your system at normal levels without worrying about sound transfer.
