im building a house and i want soundproof walls. what material do i need to use?

like what material do i need to use to build the walls and stuff? for soundproofing. like what company brand name, name of material etc.

It would save a whole lot of money if you just insulate it really well.
if you want to do kinky stuff and know one hear, I can't help you. If you want sound not to travel from one room to another. Just use standard insulating batts, walls and ceilings.
stuff insulation in all your walls.
layer the walls with six inches of pure lead that way you not only have no sound, you are protected in the unlikely event of a nuclear blast.
My friend just redid her upstairs and had peg board put in as a sound proof barrier. She said it works awesome and is not terribly expensive.
