Soundproofing One Wall, Soundproofing Options

[sethjacquay]

I am going to be moving into a new apartment next month and
my new landlords warned me about a dude in the building next door
who might complain about sound.

I am interested in soundproofing the wall that the neighbor and I share
probably about 10' by 8' in size.

Obviously, headphones would work, but when I am singing and playing
acoustic guitar I will feel better about letting loose with some sort
of sound barrier on that wall.

Any suggestions?
Does anyone else have some sort of setup they use?

I was thinking about those foam absorbers, but I read that they actually
don't block the sound and might actually cause him to hear more noise.

I am considering a vinyl barrier that would hang from the wall. It won't block everything
but should add another layer to help reduce the sound transmission directly through the wall.

Concerning the sand, if you trapped it between two partitions, you'd need to calculate to get 2.5 lbs/sq" That would mean 200 lbs for your whole wall.

I've not tried it and I'm only supposing from physics. Still, when we don't want to spend too much, and not loose too much room space, we have to be inventive. No salesman will like the idea.

Haha! I can imagine a tiny leak just over your downstairs neighbours pillow on his bed. Well, maybe not a good idea - you may get a space on the top when it settles anyway.

Good luck
