> This guy says you can build high-performance acoustic panels with old towels.
Towels, acoustic panels and other materials are good at reducing echos but it doesn't really do much at all for reducing the amount of sound that can enter or escape a room.
If you had an open room with a hardwood floor, you'd likely get a lot of echos when talking normally. That's where things like acoustic panels help out.
If you want to dampen the noise of your neighbor's kids screaming like maniacs you'd have to do a pretty serious amount of sound proofing with other strategies. It's a lot more complicated.
Sound treatment uses acoustic panels to make a room with a flat frequency response and minimal reverb. They damp the room's natural resonant peaks and reflections.
Sound isolation keeps sound from getting into and out of the room. It's a separate problem, and you can only solve it with mass and physical separation - e.g. building a room inside a room with massive walls and rubber isolation for the floor.
If you do it properly you have to pay a consultant to design a solution for you, because it's so easy to get it wrong.
