Felthove-- you're right-- weird question, and thinking about it makes my head hurt, but presumably much of it would depend on room size and acoustic properties, ie the way sound "bounces" off the walls and around the room. IMO the bigger the room and the "deader" the acoustics, the less the effect. But in a smaller more "live room", you may have chaos?? Of course theaters use multiple speakers in very large rooms, but they must be strategically placed?? :>). Cheers. Craig
Is sound "additive"?
If I kept adding speakers playing at say, 70 db to a particular room, would the sound keep increasing? Wierd question, but I was thinking about how it sounds when a room fills up and people are talking -- it just gets louder and louder (though some of this is can be attributed to people speaking louder to compensate for others' talking). I was going to try and relate this to the effect (in SPL) of adding multiple subs to a room. Would it just keep getting louder and louder?
