Desperatly Need assistance

[IndagoMonk]

I am building an in home studio and i ran into a rather huge problem.. I need everyones opinion. I am going to put foam on the walls and i just wanted to know the diffrence between these or these Aurlex Wedgies.. And just flat panels?!! Please help

IndagoMonk,

The only huge problem I see is bass buildup/uncontrolled LF in your room.

Either of these will do what they do. This is minimal treatment for reflection points. Pick your poison. They are better than packing blankets.. or not - depending on how far you space them from the walls...

You will need bass trapping & depending on room size - A LOT of it. See my publications page for more information - as well as the RealTraps site and the GIK site.

Cheers,
John

The room is 12 by 10. I will bass trap from top to bottom every corner.Im looking for something with acoustic properties. And something that will dampen the sound aswell!! Please help!! ASAP

I think he wants the short answer.

1) ASAP won't get you a better sound. It takes a lot of understanding of WHY to do what you're doing to a room instead of HOW (which is all you're looking for it seems).

2) Foam. It looks really cool i guess but for smaller rooms I'd just kill the whole freq range using "not foam".

3) Patience and understanding. You'll save time, MONEY and be better off in the end. I postponed my room build by quite a bit just to learn about acoustics. If you want to do it right - take your time. There is no "ASAP" in audio design. If you want it done right - then it's done when it's done

First off thank you all for the input its greatly appreciated! i was lookin for the short answer figured this would be the best place to get a straight up answers from some pros!

Reason i said asap is im very anxious want to use that baby!

Everyone is anxious to use their new stuffs! I had my design all planned out about a month ago and wanted to slap everything together right then and there.

Now my build has been postponed because I'm learning. I'm even going so far as to build a new, more acoustically transparent desk before starting with any treatment. Analyzing my room using programs like Room EQ Wizard and FuzzMeasure.

I've got quite a bit to go - just finished my desks - now it's time to prep the room (cleaning, lol) before getting everything ready for my first REQW test.

I'm quite happy my stuff has been sitting for the past month. It will sit with testing for another month until I know what I need to do with absorption.

Everyone wants to play with their toys the minute they have them or have the idea to. Patience.

Id be careful with this stuff, as it wont do anything for the low end problems in your room. But it will remove the highest frequency reflections.

From what I have observed and gathered, the wedges/shapes in foam is perceived by people as doing something.As a porous material it wont reflect. I think it would be better as a solid block than wedges. It is nothing more than for looks.

Honestly I'd hold on to your hundred bucks and save up. As I cant see either one doing much of anything to help you. But mainly learn, learn, learn.

is there any way to predict modes to fight specific frequencies?

lets say i calculated at which freqs my room resonates, 122hz, 101hz and 92hz

(i've calculated it by dividing 1,130fs with my room size...i should do it with proper testing i know)...but lets assume they are exactly the freqs at which my room resonates....

Now i have a modal wave that NULLS at 368 hz .... will i improve my room by buying/building 2 membranes that resonates at 92hz, and placing them at the opposite sides of the wall??

am i making sense?

will this improve the picks i'm going to have at 138hz, 207hz and so on..?

is this the math used to predict nulls and picks??

thanks

No, when treating an existing room you measure, rather than try to predict:

Room Measuring Primer

From my Graphical Mode Calculator article and software:

Regardless of what is predicted (or measured using test equipment) the solution is always the same - as much broadband bass trapping as you can manage. Whether your current room happens to have favorable dimensions or not is irrelevant, unless you're willing to move the walls!

i didn't ask the right question, sorry,

what i'm trying to understand is the second part of the question, does it make sense or its just a bunch of nonsense, assuming that my room actually nulls at 368hz .

thanks

[Ethan Winer]

Peaks and nulls are caused by acoustic interference. Some peak and null frequencies are related to the room dimensions, but others are related to positioning. For example, a loudspeaker 2 feet from a wall creates a series of peaks and nulls related to that spacing, independent of the room dimensions. So there's no simple answer, and this is why the only way to really know what you have is to measure. Now, once you've measured, you'll want the traps to absorb at both the peak and null frequencies. But since these frequencies can be all over the map, broadband bass trapping is a better solution than tuned membrane traps. Especially for frequencies as high as 368 Hz.

Was this what you're asking?

yes, thanks!
