Acoustic Tiles

What ways are their to determine the optimum placement for acoustic wall tiles? I'm guessing the best place to put them would be opposite the speakers, but I am sure it is more complicated then that...
Don't worry about avoiding any technical physics talk, iv got a brother doing a physics degree who is going to help me.
Is their any software I can use to help me.
I of course have a full duplex audio interface and a decent condenser mic to use with whatever software...
I guess i want to know of any links and get any help on treating a rectangle bedroom about (3x3 meters) to sound less reverberative and help give a flatter response for when i get my monitors. |

if you go to auralex website and provide them with details, they should be able to give you best recommendations. It's called "Personalized Room Analysis" - and it is free.

I haven't ever used the little gadget on the auralex site.. but keep in mind, they're in the business to sell you product.
If you were going for a most minimum setup... i would suggest adding a foam surface to as many 'reflection points' as you can.. between you and your monitors.
example... if a wave that didn't head straight to your ear went all the way over the the wall on the left, and then reflected directly into your ear... that sound would take longer to get to you than the direct one. eliminating these 'rougue waves' i think is the cheapest, and easiest way to get started.
the walls / ceiling roughly half the distance from you to your monitor would reflect a wave back to your ear. This applies to a lot of larger control rooms.. if you're in a tiny room with nearfield monitors 3 feet from your ear, this concept may not be as applicable.
I learned all this from John Storyk. |

First thing you want to do is check your room modes and do all your treating in reference to that. Get yourself and your speakers in the right position acording to the dimensions of the room FIRST. Make sure everything is as symetrical as possible - ie. having a window running down one wall but not the other is going to change everything completely. Run a sine wav generator and check the results are in line with the room modes.
In a symatrical room, you want your acoustic panels to be placed behind the speakers and either side of the listening position (or either side of the speakers depending upon the angle) to colelct early reflections. Also, you want to place diffusors and absorbers on the entire rear wall. If bass is a problem (which it will be in a room that size) treat the corners with HIGH DENSITY bass traps.
These principles are all well and good, but in a room that size you're probably going to need to absorb alot more than just the typical minimums. I wouldn't really bother with diffusion, unless you build it into an absorber. A good way to build an absorber/diffusor is to take an open backed book case, fill most of the comparments with rockwool and the others with books and any other junk to bounce the sound around.
Also, don't buy your acoustic treatment. Do it yourself. Unless you have a few grand to spend on this there is no way you will get quality products - decent priced non-diy panels cost 10x (seriously) more than DIY solutions, also they provide little room for customisation. Foam is generally not fantastic unless you get high end auralex stuff.
Let me drill this point home. Bass is going to be the main problem in 90% of home studios. Also, dance msic obviously has HIGH bass response requirements. Those 12" tiles you buy WILL NOT DO ANYTHING for bass. They "may" work well for higher frequencies, but won't do for the low end. Don't waste your money. Also, when you glue a tile directly to the wall, you limit it's usefulness even further. Ideally you want a gap between the wall and the panel. Get unfaced 60kg/m^3 density rockwool for the high absorption, and ~80-100kg for the corner traps. 100mm thickness is ideal.
Positioning panels isnt really that difficult, you just need to think in a similar way you would light rays. |

Forgive my ignorance, but what do you mean by "room modes"? |
