Basically, your material has to absorb the sound.
Lead makes a good material- it takes a lot of energy for a sound wave to pass through a sheet of lead.
If you can't afford lead, or it is too heavy to use, use layers of material with different densities (sound waves lose energy at interfaces (the place where different materials touch).
if your on a budjet then cardbored egg trays with cotton wool inside works
or even better a sheet of cork with a layer of leather over it an then plasterboared
A vacuum.
Sound requires a medium to travel through.
Remember; in space, noone can hear you scream. ;)
For the rest of us stuck on Earth, standard fiberglass batts are as good it gets when used in a sealed wall or ceiling cavity.
The important parts of soundproofing are sound absorption, damping, decoupling and mass. For walls and ceilings, materials such as fiberglass and whisper clips are recommended. To soundproof floors, using a sub floor and fiber board is recommended.
There are many materials that work well for sound proofing, but convoluted foam works very well. You can buy it at Walmart or some store like that for not that much money. I hope I helped!
you can use several egg cartons
acrylic
Protoplasm is all the living material that makes up a cell. This is the substance that is surrounded by the cell membrane.
Density is the amount of material which will make up something. Density can be varied accordingly to make items of the same material, but for different uses.
Vinyl and PVC are both cheap waterproof materials, but they don't breathe and can get kind of hot. I don't think of them as a very good material, but they are waterproof, and good if you think so.
Ceramic
i would say lead but good luck lining your walls with that it is toxic. It IS the best soundproofing material known except for "Aerogel". It is only toxic if ingested.
There Are Many Good Soundproofing Insulation Materials, but Insulation and Mass-Load Vinyl Seem to Be the Best. Mass-Loaded Vinyl and Insulation Are Good for Filling Gaps.
Check out your local Yellow pages. Check the front and/or the back of the book for coupons. This will help you find a reliable soundproofing of your liking.
Soundproofing foam is a good method for sound proofing. There are also several other good methods for soundproofing a home.

Rather than soundproofing the window after the fact, windows are made of soundproof material. You can get information about that here: http://www.soundproofwindows.com/
They are made of a special soundproofing material keeping your sound in and other sounds out.
it makes it a good material because it helps you make houses that will stand up and will protect it from guns
Experts say it is just not the foam that's important, but the mixture of a good foam and acoustic materials. Check out soundprooffoam.com for all your soundproofing needs.
No shared electrons between neighboring atoms/molecules in the material makes for a good electric insulator.A good thermal insulator has lots of air or gas (which insulates) trapped in the material.
Hot molecules moving makes a good heat insulator
"dry" soundproofing is a mat consisting of some sort of fiber like a poly material or fiberglass. "wet" is tar like and dries after application. a third is like a thin sheet of foam which has adhesive applied to the back.
