Custom maps lagging out

[Ogami]

Whenever I try to load my map, which is a quite basic 4 level house and only has a few furnished rooms, it completely lags out because of 'sounds' that start generating from absolutely nowhere. I don't see how static, nonmoving furniture would be calling all of these sounds, especially when there's not even any scripting on them. Anything I can do, or do I have to separate every single room into a separate map?
