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.

I've been reading a lot of those 'studio makeover' features in various mags like 'sound on sound' etc. Almost all of them have plenty of good advice and tips for banishing standing waves etc. with expensive acoustic tiling, thereby improving the sound in the studio, but skirt around the issue of keeping the sound *in* the studio to avoid midnight homicidal encounters with irate neighbours.
I must check out those links myself, as I'm getting nearer to making some noise when my kit arrives.
Hope you got sorted with yours, cheers, John
