Hey Everyone,

Over at the AV Science forum a gentleman named Ryan set out on his own to do a case study with room treatment, setup and EQ.. I think he did a outstanding job on this.. You can check out the final results at.

He did a very good job.  

I have yet to read up on Dr. Geddes' approach to room treatment but I can tell you that it wouldn't be hard to implement and was quite effective (I got a demo of his theater room).

The end results ESTA INCREIBLE...WOW - easy to understand...

I really need to get a mic and that free software (I think its free)....it will probably take a while for me to understand what Im doing..nevertheless fun and educating

very easy to understand.. That I think is part of the problem  with acoustics.. We get so deep into the science that we end up turning people off...

Excellent.

More people need to realize how important this is. And as you explained, it's not that complicated either. Click HERE to see another useful case study that shows the huge improvement from adding traps and other treatment. Lots of graphs and good explanations of the principles.

That person needs a helmholtz radiator with low Q centered at whatever frequency that lowest mode is.  That or a notch filter/Digital EQ.

[ctviggen]

Also, why does he have the high frequency oscillations, both in the frequency domain and the impulse response?  The impulse response particularly is suspect -- after 18 ms, he still has wild oscillations.

Also, I see that his room is 4.3x4.3, which is what's causing the massive mode at about the 30Hz mark.  I still don't understand the impulse response, though.

Ethan can you check that link? It seems to go to a review of Real Traps, not a case study..

Glenn, you crack me up!!!!  

I hope my article is helpful to anyone considering room treatments.

Ryan you did do a great job on this.. I have gotten a lot of feedback about how well it explained things..
BTW, I really thought Ethan posted the wrote link.. Turns out it goes into some pretty cool stuff after page 1..

I actually thought the same thing..I saw a review for Real Traps but then I read it anyways..heck REAL Traps has LOADS of great free info on their site and their product seems to be proven - it was pretty good/cool...although I understood more on the link you provided...it seem to be explain in lamens terms.
