Sound Proofing  Reply with quote  

One cheap and pretty effective way is to make curtains out of old blankets, the thick sort that you would use in winter. In the states you can go to Good Will or an equivalent thrift store and buy them for like $2 a piece, which is about as cheap as you can get. Then you nail, staple or otherwise attach them to the wall or ceiling. The ceiling is better by the way because you can leave some space between the curtain and the wall. This will help to deaden the sound better than if the curtain is flush against the wall, but as with everything, you have to do what works for you. You can minimize bass traps in corners by adding additional blankets there.

soundproof an entire wall  Reply with quote  

how bout those mats they use for fitness and little kids that come in puzzle pieces. They are made out of hard foam. I need something really good, not only for recording but for killing sound at night so I dont wake people up when I talk or watch TV. Basically, I need to soundproof an entire wall and the booth while allowing me that take it down at anytime. Any suggestions for either or both of these situations?

suitable absorbtion for sound insulation  Reply with quote  

Hard foam, and things like it may be suitable for isolating amplifiers from the floor, but in my opinion do not provide suitable absorbtion for sound insulation. The GRAMMA by auralex is quite a nice prebuilt unit for decoupling amplifiers from the floor, I think you could use hard foam for a similar purpose. As far as isolating a wall from your neighbors, that may be difficult in a format that is portable. Mostly you will have to focus on low frequencies as high frequencies tend to bounce off hard walls rather than cause them to resonate. There is a good site, I think it is owned by auralex that addresses a bunch of acoustics issues. www.acoustics101.com It has lots of diagrams too. Also, they have a material list that lets you know what kinds of materials absorb which frequencies best. Quilts do provide respectable dampening characteristics even though that might not have been what you expected to hear on this bulletin board. While not as "studio esq" they can be every bit as effective as egg carton foam. The use of heavy curtains is actually a faily common practive, they just don't use blankets as curtains. Let me know if that helps.

two layers of insulation  Reply with quote  

Taking the advice you gave me, I've thought up something that might be good. I'll let u be the judge. I'm thinkin about making connecting walls that have removable pins. The plan is the take some 1/4" to 1/2" plywood and make multiple layers. On the outside is most likely speaker box material then the plywood. Then on the inside, two layers of insulation seperated in the middle by a thick blanket. I also just found some goosefeather bed-toppers and I'm in the process of figuring out how to incorporate them into the design. Reply back and let me know what you think.

sound travels through air  Reply with quote  

That sounds like a good design. One of the things that will greatly improve your overall design as far as isolation from your neighbors is the air tightness on the top and bottom of the walls. This can be done simply with pillows, blankets or equivalent material to fill in the gaps. The same will probably go for the places where the walls connect. Your room deadening should come out quite sufficient from what I understand from your design. The reason for filling in all of the cracks has to do with the fact that sound travels through air. No air flow = the sound has to travel through something else other than air, which will greatly decrease the volume of the sound. Great ideas though.
The point is, if you feel that you are not getting the isolation you expected, you need to focus on sealing your temporary walls.

Temperpedic  Reply with quote  

yea, I also figured that into to my plan. I was going to use that foam material you see in commercials that beds are made out of. The material forms to the shape of your body when you lay on it. I think its called Temperpedic or something like that. I figure that if it forms to your body, why not to every dent or warp where the edges meet. I have it at my job and seems like a pretty good thing. Plus, it looks like it would be a good sound killer by itself. It's rather expensive but the best plan is to just buy the bed topper and cut it into strips. let me know what you think.

Sound Proofing a Studio  Reply with quote  

I have found that www.soundprooffoam.com is a tremendous resource for soundproofing a studio, room, floor, window or door. The site seems to be geared more towards people that need cheap, high quality sound proofing materials.

I have purchsed some eggcrate studio foam it does a great job reducing the mid to high frequincies in my vocal booth.

Another great resource sight is www.howtosoundproofaroom.com

it covers a wide range of applications.
