Does anyone know if these are good for sound proofing in a home theater? I plan on sealing these around my glass block windows. Will it suffice or is there a better item/idea from anyone.

those won't sound proof anything. but if you put, say, 10 layers of them, it sure will help.

 

[Mijotter]

Well then I want to make sure I put whatever is best over the windows as, once the walls go up, I can't just redo it. Any suggestions? I've heard an extra layer of batt or doub le layer MDF with green glue and gasket over the window. Your thoughts.

Soundproofing your window will reduce noise levels by 75-95%. Utilizing foam pads are used for deadening reflections. While felt blankets are what the professionals use in studios and on stages for sound proofing. Hope this information helps you.

when sound proofing, "mass" is KING !
decoupling is not far behind.

i would not "cover" a window. as in, leaving the window alone, and then covering it with a wall. i would take the window out and frame/fill the hole. this will also give you much better attenuation.


just a warning = those foam acoustical panels will do nearly nothing for sound attenuation. like these. though they look cool

Well we had the windows replaced with glass block when we moved in with a small open/close vent in the middle of each window. I won't take the windows out.

I assume the glass block replaced windows to the exterior as opposed to a interior mostly glass partition. Is your concern sound transmission to the exterior (neighbor) or the hard surface inside the theatre that will cause sound reflection (echoe)? Also, when you closed up the original windows and installed glass block with a small vent; if the window was your emergency escape and rescue opening for a finished basement then this is the time you would want to put it back.

 

[Mijotter]

My main concern is putting all this money and work in to SP my basement only to find out the windows weren't done right and are the weak link. everything is down now so now is the time to do it right. Mainly I want a little sound coming from my basement as possible. And no the other side of the basement has the fire escape window.

Also, what would be a suitable gasket for whatever i place over the window? Thanks.

Trying to figure out how to proof them as the cavitiy is only 3/4" deep. I was wondering if that sound putty would work spread over the whole window then maybe 1/2" moisture resistant drywall over that sealed with acoustic sealant. Over that is going to be 2" xps rigid foam board directly on the concrete wall then studded with bats in between then DD+GG.

3/4" plate steel.

 

[Mijotter]

Plate steel? as a soundproofing component? Here is a picture of the window.

you need "mass". and you don't have much room if it. i was just thinking, cement board, that stuff is pretty solid and thin. e few layers of that would helpa lot. but remember = good bass has a way of moving things.

 

[Mijotter]

That's a good idea. You can get 1/4" cement board. Any ideas on how to have it stay in the cavity and seal it?

 

[rylahn ernandez]

1/4 cement board would definitely fit.

 

[Fix'n it]

if you are putting a wall there, you will have extra room for sound proofing.
when building the wall, frame out around that window = don't cover it.
then build your "plug" to fit snugly in the opening.

Treat the window opening as part of the wall cavity and soundproof accordingly. Adding mass will improve the sound proofing of the window as mentioned. I would caution you not to leave any "empty" space in there as you can inadvertently end up with a resonant cavity that could transmit a lot of sound.
