Cheap and Easy Home Theater Soundproofing Tips
Bona-fide soundproofing is neither cheap or easy. Anything short of building a “floating” (isolated) recording studio type listening room won’t totally soundproof a room. You see, a floating room’s ceiling, walls, and floor are acoustically and structurally isolated from its surroundings. Prices vary, but plan on investing at least $10,000 for a professionally installed floating room.
After the floating room construction techniques, you can attain more limited success with double sheetrock on the walls. That is, install new double sheetrock walls with an air gap between them and the original walls. Double sheetrock can make a big difference, but it’s still far from a cheap or easy solution.
