Snowcrash Soundwave Acoustical Wall Panels are one way of dealing with soundproofing while keeping your pad looking good. The Snowcrash Soundwaves are from Stockholm, but we had trouble getting to their website. They are also available at the Apartment Store (no relation) where the 23 inch squares cost $120 apiece.
Snowcrash went out of business, however Offecct bought the rights and is offering the panels. The direct URL is:

I hope this saves someone some truble.

If anyone is interested I have nearly 500 Offect Scrunch style panels in the unfinished color. I can sell these at much below their retail price. Email me or call 301.643.4019
