OH MAN!  I shouda used hairspray then!

I'm no chemist, but I believe hairspray isn't flammable, rather it's the solvent that is. Once that evaporates, the gluey stuff that remains shouldn't be any more dangerous than hair gel.

Although I'm not convinced that such treatments won't change the physical properties of the fiberglass, I would think that any loss of absorption would be in the higher frequencies where it's not necessarily a bad thing. It certainly would not be an issue for bass traps. You can cover the stuff with plywood and it still functions as a bass absorber.

I'm not a chemist or expert either.  but here's where I got some of my information:

http://en.wikipedia.org/wiki/Hair_spray

granted, there are not citations so this is just someone's opinion.
 
colin- I've got wooden frames and burlap covers as well - which of course will burn, but by "flammable" the term implies "accelerant"

Hair spray on your room treatment will filter out everything that doesn't sound like 80's Metal.

Beware.

I have bass traps made of a blend of Joey Tempest's and Bonnie Tyler's hair and I still have enough left over to equip another 34 good sized rooms.

Great for that authentic subtle Jim Steinman sound but probably a greater health risk than glass fibre, especially when you factor in trying to get into a pair of 26" waisted red jeans...

I need to let rip...

This is what I came up with on a budget, for 200 bucks for a kit of wall sound treatments, 2 4ft panels (26 bucks each) and 2 large acoustic treatment blankets, far left ($44 bucks each)
The sound blankets effectively cuts off the left side of the room which caused me lots of acoustical problems as its a hallway and all tile to the left.  I have no large bass traps yet but my room sounds alot better and has more clarrity with these little fixes.
-Treament behind monitors
-Treatment on side walls between monitors and my head
-Treatment on celing between monitors and me
-One lone treatment along long right wall and one on rear wall opposite monitors(was running out of treatments)
    Anyone see any obvious problems with the set up? 

Thanks for the tips Dave, its hard to tell in the picture but the speakers are around 4 inches from the wall, I read 2 1/2 feet is a good number for for storage and space reasons that will be difficult to do. 

When I collect more material I will put a couple more on the ceiling, I still have the back wall to do :(.  I had doubts about these blankets but it turns out, they are great compared to my existing -nothing- that was there.  That made the biggest difference so far.

Using a condenser mic and a pink noise generator (and SPAN) shows that I have a big spike around 150 hz and a huge drop off around 8K.  I dont know how accurate this test is but it seems the only logical way I can test the room.  I wish I had readings from before I treated the room

Having a little bit of spray ahesive on one side of the panel isn't going to interfere with "particle vibration" any more than leaving one side of the craft paper on the stuff or leaving it in the plastic wrap.

I used 703 and burlap myself, but chose to not use any sort of adhesive spray.  No slippage or bunching probelms after they've hung for a couple of years.

But I do know folks that have used adhesive spray to be "safe".


 
Here are some shots...one of my live room and one of the control room.  I used 3 different colors of bulap in the control room.  Note the very dark brown used in the vertical corners.

 
(edit - spelling)

So skull,


Do the 4 boys work better as absorbers than 705?

Anyone seen or used this stuff:
Sound Choice

saw it at Home Depot. I was singing into a stack of it and it sounded pretty good.
4x8 sheets. $20 per.

 This is a drawing i did of my current rental house setup.. My wife gave me a damn closet to work in.  Both my control room and my record room....But you guys heard what came out of this small room...Enemy of Earth stuff.....

Anywho... I made furring strip frames 3' x 3', added a 1/4 piece of paneling, then spray glued the aluralex foam to them. 4 screws in the corners of each is better than scraping foam off the walls later. i can move them, without harm. no vibrations.  as for the corners, i have 2' tall triangle foam with little pyramids tacked up in the 3 available corners of this closet....hehe

my question now is, am i too close to the wall ? the speakers...I am justified left a little, not very center.  but the room is dead...

what you don't see is all the guitars and cords and junk i got in here, racks, it's hard to set up in this house, but i have to deal with it. i want to put a small couch behind the computer chair. it will definitely fill the room...maybe a bad idea.

Love this thread-Great Ideas with just getting back into it myself. I have a room Im converting that is 16'x20' (320 sq ft). Here is a site I found that can generate good ideas if you are handy and it also has an outstanding calculator for deciding what you should use and sizes. I also did a report for my room to get started.   The Table/Chart did not display so its hard to figure that part out on this posting but does come out nice on site.
 
As for what the measurements on the table do indicate-I will need 40-45 panels depending on the response Im wanting.
 
All the info on the Bass traps posted does spark a question for me though. If all recommended panels are placed and I dont actually use a drum kit in this room, should I still add those as well? I record all guitars and basses directly without mic'd cabinets.
 
As for budget and prices-They also sell everythging from DIY to custome work. The prices appear to be good when comparing online to everyone else and are fairly inexpensive.

Notes:

1. Reverb time or RT60 is a measure of how long it takes for echoes and reverb from a sound in the room to die away until it is 60 decibels quieter than the original sound. This is similar to the time it takes for a very loud sound to die away in the room until is barely loud enough to hear at all.
2. The target reverb time is based on the room's purpose you selected in Step 1. For example, a recording studio has a lower target reverb time (0.20 to 0.40 seconds) than a home gym (0.50 to 1.00 seconds), because it's ok to have more reverb in a home gym than in a recording studio.
3. The reverb times shown in the table above were calculated using mathematical equations that model the behavior of sound in rooms. The dimensions of the room, and the area and acoustical properties of each surface material in the room are taken into account.
4. Reverb time is different for each sound frequency (hertz, or Hz), because surface materials absorb more of some frequencies than others. Whatever sound is not absorbed (or transmitted) by a surface, is reflected back into the room. Six representative frequencies are shown above.
5. The primary purpose of most acoustic treatment is to bring the room's reverb time to an acceptable level. This is especially true in medium to large rooms. In smaller rooms controlling reverb time is a lesser consideration, and acoustic panels are used more for reducing out-of-phase reflections and flattening frequency response. So in smaller rooms (for example the size of a typical bedroom) more panels may be needed than indicated by this reverb time report.

Thanks again for the info and hope this helps anyone looking to get ideas on what to do also.

What say you geniuses about this stuff for traps and treatment?

I don't understand your post David.

Thanks Tom. Lots of good reading and pics over there. Great stuff..
