Sound Insulation- how much can it help?


I am considering moving into a new apartment, but the neighbor's (with yound child) bedroom is right next to my living room. I want to listen to music and watch movies at fairly loud volume late at night. At a volume that was way too low for me, i.e. I need it 3-4 times louder at a minimum), they asked me to turn it down another half. We have concrete walls, and with a fairly large (5 meters long and 5 meters high- vaulted ceiling) shared surface area. Is there any soundproofing method that can work? How much sound can be reduced? At what volume will I be able to play my music any time of day or night?

You might consider mounting a "floating" wall -- which is drywall mounted on resilient clips. Search "soundproofing" in these forums, it's been covered pretty thoroughly.
Jeff is probably right, and you can save a ton of money by replacing amps and speakers with the absolute best headphone setup.

What you seek is impossible.

Sorry.

You cannot the violate laws of physics and the propogation of sound waves through walls/floors is one.
Wall to wall style carpeting can work wonders applied to walls, doors and ceiling. Almost relevant, we used it once to insulate a wood frame garage for band practice. The best is heavy wool pile, very plush and heavy. You may need to screw some kind of lath to your walls to hang it. On the downside, with the bodies and equipment in there it got really hot sometimes! The police still came but after witnessing our efforts to protect the public and securing our verbal agreement to respect the 10 o'clock noise ordinance we did OK. From an equipment perspective, stand mounted speakers that trade finesse for pure grunt may be a partial solution.
