I cannot get OC703- OC703 here to make first reflection panels or base traps, although there still is a product similar but for the same cost I wonder if this is as good or better for a DIY reflection panles and acoustic panels. I can make 2' x 6' panels with this just double up on the layers. It is $30 a 4' x 8' sheet.
I am also going to put it on my studs before sheetrock, but thought it would also be good as an acoustic panel in stead of compressed insulation

A great alternative that is available in most parts of Canada is CertainTeed. The best in their line is CB300 which is identical to OC703 in every manner, including acoustically. The published coefficients for CB300 are in effect the same as OC703, and this material will be MUCH cheaper than the Sonopan insulation. Where are you located exactly? I may be able to point you to a local dealer of this material.

Cheers,

While looking for some oc703 I found http://www.gikacoustics.com/ My eyes perked up when I saw an EP600, then I realized I'd seen that room before. It belongs to our very own Brother Bob!

Hello,

If I may jump in, are these OC703 panels put up before the drywall goes up, in the construction stages?

Also, are they for sound insulation (so that my kids, two rooms down, are not too bothered by the movie playing), or are they for preventing sound from bouncing around in a room without much carpeting, furniture, curtains, etc.? I've read that a room can be too bright if it's mostly bare walls.

Thanks,
Rodney

Rodney,

Bass Traps and First Reflection Zone panels are used to absorb certain frequencies not insulate, and are placed within your room.

Bass Traps are normally installed in corners of rooms, including floor/wall corners and wall/ceiling corners where lowww bass hangs out. This helps flaten out the overall frequency graph down low.

FRZ panels are intended to be placed on walls and ceilings and help with the mid's and higher freq's that arrive at your ears later than the direct sound.

Rodney,
Yeh Two different things here ...
what I am talking about goes on the outside.
You want and there are numerous ways and products , but roxul sound insulation for and resiliant channels etc. There is lots of information on this on the net.

PM me I can give you lots of websites on contructing a sound proof room

Hi Rodney,

As mentioned above, there are numerous websites that feature and depict DIY Acoustic panel designs and implementation. Some of the DIY designs and plans have been adopted by commercial acoustic panel companies and are offered for sale at low cost. www.gikacoustics.com is company that offers lowcost treatment options. Here are a couple of very good resources for DIY absorbers:

There are more, but I believe these sites have diy plans for every budget.

Good luck,
