Uniformity of gap between walls
Posted: Wed Jul 09, 2003 2:54 am
Hello everybody.
I've got a quick question--what effect would differences in the gap between the two walls of a room w/in a room construction have on interior acoustics as well as the total sound isolation of the room?
For instance, if 3 walls and the ceiling have a gap of 6 inches, and the fourth wall has a gap of, say, 12 inches, what effect would this have on the interior sound of the room and its ability to keep music-type sound from getting to the outside world?
I've read in Everest's book that larger gaps help to absorb lower frequency waves (to an extent, and with diminishing returns), so would the entire room benefit from having one gap larger, or would a difference be noticed in just the one wall?
I would think that the sound passing into the smaller gaps would seek the path of least resistance and flank towards the larger gap, thus improving the isolation of the room--maybe I'll just try it and see.
I imagine any responses to this would be purely speculative, but I'd like to hear some other opinions if anybody's got them.
Thanks
