Built soundproofing panels, but they still need work...
« on: July 22, 2013, 05:17:18 PM »
Hi there!

We built temporary soundproofing panels to lean against a wall that we share with a neighbor, as we're renters and can't do anything permanent to the wall underneath. The sounds carrying through the wall are mostly voices, but also music and TV.

We made a frame of 2x2s and attached a layer of sound board and then a layer of regular drywall on top.

The panels are okay, but as you can guess, sound is still coming through, probably because of the 2-inch air space behind the panels created by the frame. We also have yet to seal the crevices between the panels as we're still gauging the level of soundproofing we have so far. AND, the walls are 2 inches taller than our 8-foot frames, so we still need something to fill the top 2 inches.

As our landlord isn't paying for any of this, and we've already spent about $500 on it, we're looking for affordable solutions for filling in the 2-inch airspace behind the panels created by the frames, and also for filling in the top 2 inches between the panels and the ceiling.

Thanks!

you can fill it with just about anything that is absorbent like cotton fiber insulation or mineral wool.
Most important is the mass of your system needs to be equal thru out the entire wall. So build the missing 2" at the top, you can probably just use a header 2"x 4"
and you will not see full value until the system is sealed air tight.

Thank you, Randy. Yes, once we fill in the crevices between the panels, the back airspace and the top wall space, I think we'll see some good results.

Like Randy said, Air tight.

That's the trick. ;)
