How Can I Make A Room Completely SOUND-PROOF?

Question

i've seen sound proof booths at electronic stores where they have loud sub woofers, they test out for customers, but its not completely sound proof, but rather lowers the sound from being louder than in that small room.....

so what do they make sound proof rooms out of, like what the materials are called. im thinking of making a studio and i can not have a studio with real loud music thumbing in the nights, without having the cops say turn the music lower or i can get disturbing the peace, or something i forget what he said.... the room is about 20feet by 20feet (higher estimate) so how much is this gonna run me couple thousands of dollars? i want to be able to be silent out side room when music is loud.... please and thank you

Answer 1

The military has actually made near soundproof rooms by doing all of the standard things you would do to make a soundproof room and then hoisting THAT room up with steel cables and suspending it in mid-air in the middle of ANOTHER enclosed soundproof room.

A lot of money and a lot of space, but it helps!

No such thing as a completely soundproof room, by the way, unless it is completely surrounded by a vacuum.

Also, insulation and sponges and stuff don't work as well as closed cell foam that can be found at guitar center. It has angled reflective surfaces and captures the sound quite well.

It will definitely cost you some bucks but to soundproof a room you will have to do so construction work. The sound waves are transmitted from the inside to the outside through the solid beams -- basically your walls transmit the sound. The interior walls absorb the waves which then travel through the wallboard and into the 2X4's exiting on the other side.

The way to avoid that is to create a 2 wall system where the sound will be trapped in the dead space between the walls. If you have existing walls you can cover them with extra insulation or just build the outside wall of the system next to (not against) the existing wall. You don't say how much ceiling room you have but if you want to make it really soundproof just rotate the wall system attaching the lower (interior) part to the interior of the wall and the top (exterior) to the exterior part of the wall. If it's going into an existing room you could get away with 2X3's and forget the exterior part of the ceiling, span the 2X3's from the interior wall (make sure to brace them together) and leave 2" from the existing ceiling to add insulation. It won't be recording studio perfect but it is cost efficient and works great -- Most of the crap out there is just that crap to make somebody money.
Good luck

Answer 3

Completely Soundproof Room

Answer 4

The only thing that completely blocks sound is a vacuum, meaning a space that is devoid of air. So leave a continuous internal air gap in the wall you're building, and then use a strong pump to suck all the air out of that gap. This is very expensive, but in theory it should be the most effective method of soundproofing. Only problem is, you'll still need to soundproof whatever is keeping the room suspended in the vacuum. Hope this helps.

It's not going to be cheap. There are lots of composite sound absorbing materials out there these days and some manufacturers will offer the whole package including fitting. If there's a window, triple glaze it. Double outer, single noise spaced inner. Practice studio I went to recently had a double door entry system like an airlock, only smaller, to keep the sound in. Finally - egg cartons glued to the wall do not work.

Answer 7

You have a lot of good answers, and I think you can see a couple of thousand dollars would be a drop in the bucket toward the actual cost of the soundproofing. More like about 5 times that price to do it right.

Maybe you can find a 24 hour rehearsal studio in your town. We have them here, and the money you would spend on remodeling your room would be better spent renting professional studio space.

type "rent sound studio" + the name of your town in your search box, or "musicians services"

Answer 8

Save and install used formed paper egg cartons. The repeated cones shatters sound like waves crashing over reef
mutes water forces. Never use any fouled by broken egg(s).
Collect pre-owned cartons from friends and dumpster diving.

Answer 9

Well to be totally sound proof you need a huge budget. I can only recommend one site that can help. They have many different recommendations and price estimates as well and explain how it can be done.

Soundproofing is harder to retro fit than to purpose build. The studs in the walls can be staggered across an extra wide plate for better STC (sound transmission characteristics). Lead curtains are often used.
