Exactly.
Saying that this is hazardous is like saying you will get cancer if you have a box of cigs in front of you.

hey guys...
im starting arrenge my "home studio" and i have thinking in rockwool, because i have a big problem with reverberation (there is a lot), but wen im starting to read this great post now im gonna thing 2, because that problem about heald.
What is the better material (quality/price$) to absorve the reflex.
And 1 more thing, my studio have 1.80 meters high. Tis could be a problem or not?????
Great tips...keep going |

Try foam if you're concerned about rockwool. Don't buy Aurelex though unless you're rich. Look around online for a foam supplier (ie Foam Express or Foam Factory) as they often sell 'acoustic foam' at substantially cheaper prices than music stores/websites. Plus it looks great visually.

Another good source of info, and offers a product for the more value minded buyer, is
http://www.gikacoustics.com/education.html
I've been researching for months, & all sources say the same thing, if you want to tame bass response, foam just doesn't cut it, you have to use thick, like insulation.

Fuzz, foam won't absorb really low frequencies which is the area most rooms have problems in.
If you guys are worried about rockwool being un-safe then you can also use fiberglass panels similar to Owens Corning 703/705.

This is what I'm using. But those are still mineral fibers.

yeap ,, foam will reflect low freq the same as the wall does
Owens Corning fiberglass is awesome 
i wish there was in europe too but you can find similar products
ALWAYS look for the specifications sheet of the product you buy
you have to know the details of what youre buying .. Usually the spec.sheet mentions the absorption factor in some specified frequencies (same for all manufactures)
Look at what Ethan Winer says about this , in this article has also the absorption factor table of fiberglass 703/705 (705 btw is the best material for low frequencies absorption in the world ,, much more than the expensive acoustic panels) which is the same as what most of the manufactures mention on the specification sheets
http://www.ethanwiner.com/acoustics.html#mhf%20absorbers
And about rigid fiberglass density here:

Nice links.
I wanted to refute that foam wouldn't work well for low frequency absorption, but after reading through those articles I must admit defeat. Fortunately rigid fiberglass is relatively cheap so I'll be picking up some sheets to put in the corners.
My room just keeps getting smaller and smaller...
Thanks all.

Yea. Lowering volume won't help you eliminate acoustic problems.

There are alot of things you can do BEFORE acoustically treating your studio.
Orientation of your setup is critical. Since you cant resize your room you need to work with the shape and make it work for you.
Symmetry is #1
No treatment:
If the left side of your mix position does not match your right side or vice versa you might think about angling your set up so you are not facing the shortest wall in the room but the corner. this will minimize the asymmetrical first order reflections that you want to eliminate, This isnt the best solution but if you dont have cash for acoustics then it will do.
Treatment:
Make sure your speakers are at least 12 to 24 inches off the wall and (NOT LAYING SIDEWAYS)
2 to 4 inches of acoustic foam or fabric wrapped fiberglass is a good choice for the front wall and side walls up to the mix position
only use diffusion if you have a back wall at least 8 feet from the mix position, anything closer will cause phase issues.
bass trapping may be needed in front corners or select areas in the room.
mode calculations will help you find out where the peaks and nulls will be.
I can tell you a great way to find out the frequency response of your mix position with spending little or no money. If you are successful in recording the following .. I will analyze it for you and send it with notes.
Materials:
Download Gratisvolver from Syn-aud-con.com
you will need the provided sweep to run through your system.
You will also need an omni directional microphone - these can get expensive but i know berringer makers one that is like 80 bones.
you will set up the mic on a stand at ear height at your mix position.
play the sweep file through your speakers and record the wave file.
this wave file will then be placed in the gratisvolver program and convoluted with the original wave (just in reverse)
this process creates an impulse response that contains information from all frequencies at your measurement position.
The impulse file is what you can send me .. I will plot the file using FFT to show the time and frequency response.
once you have the frequency response you can then start to "tune" your room.

If you are thinking of using acoustics..Use a combination of Auralex and RPG all else is JUNK>>> |
