Need to soundproof small bedrooms. I am not asking for 100%
soundproofed rooms, but at least a 50% reduction in the noises
carrying from room to room.
Is there a cheap and, more importantly, _easy_ way to do this?
A friend of mine believe it or not used the trays you get at coffee
joints , Tim hortons etc. and covered one wall in his son's room with
them . It works fine I guess and looks rather neat as well. You can
paint them and add to them as well.
Sound has some basic principals that you can use to lessen the noise
1) Sound loves hard surfaces (helps it bounce around)
-Soften the room to obsorb more sound
2) Sound will travel where air leaks (Change doors or get rid of the air
3) Sound travels in waves (Soft materials that are diamond shaped will break
this wave and obsord it.
Things that work for absorbing sound
1) Sound deadning insulation
2) Sheets of drywall hung on Z channel isolators
3) Sound Board
4) Egg carton foam
5) heavy soft rugs or sheets about an inch away from the wall (You'd be
How cheap is cheap, and do you/ not want to open/ patch the wall? When
my bro who lived w me was learning to play sax, we pulled off panelling
and had cellulose blown into walls. This was a rental. Landlady
arrived in the middle of this and nearly had a heart attack. I also
opened up hollow door and filled it w corkboard, which my bro got free
from company that was chucking it. Helped a lot. If you don't want to
open/patch wall, I'd agree with above.
To add to that read: http://www.soundproofing.org /
In general you want to block air exchange. Air caries sound very well.
(Try opening your car's window as a train is going by.)
Next you want weight. Heavy things (drywall lead sheets etc.) block
You also want to prevent any direct solid connections. Stagger wall
studs or use special isolation devices to keep the sound from traveling
through the wall (remember the two cans on a string (well wire actuarially
worked) you want to break the wire).
Filling in wall cavities with sound absorbing materials (accustical
fiberglass bats) will do a little.
Point source control (special absorption material) at the source of the
sound will also help.
Recent issue of Journal of Light Construction has an in depth article
on this topic. Pick up a copy or it might be available for a couple
of $ from their web site: www.jlconline.com
