to float or not to float ceiling
« on: June 03, 2005, 02:55:35 AM »
I am currently debating whether it should be necessary float the ceiling in my master bedroom.  I live in a one story (ranch) house with nobody above me.  So there's just an attic with insulation up there.  I do plan to float the walls with RC and MLV + 5/8" drywall.  Do you think I will be losing out if I do just the walls but not float the ceiling?  If its not necessary to float, should I :

(1) add MLV over the existing drywall on the ceiling and add another sheet of 5/8" drywall

(2) just add another sheet of 5/8" drywall on the existing ceiling

My concern is would I be wasting my time floating the walls but skimp on the ceiling?

One of the rules of soundproofing is to put barrier material between the source of the noise and the target.  

If there is no noise (A direct sound path), than soundproofing the ceiling may be unneeded.

Indirect soundpaths are not usually a problem because the sound has to take a longer route to the target, so loses energy on the way.  (Sound loses energy to the square of the distance).

You could do the walls and then see if the ceiling is a problem....
