Any specific ways to tell that the treatment is working.....I think i hear a difference. But how do you guys tell? Besides using some type of testing equip.....
 
Yes, for that reason, echoing (slapback, etc.). You should also notice some deadening of the highs/upper mids, or with music you maybe will hear the high end as a little more defined.
 
What sort of treatment have you done? Is it only stuff addressing higher frequencies and controlling flutter echo, or have you put in some bass trapping too?

Well i got some 5in thick foam from work...they were throwing it away....really dense stuff. I have it on the walls and corners and ceiling.
 
I think its working....cause everything sounds really dead at the listening position.....Like mouse clicks and keyboard....its hard to explain.....like more detail...lol Music sound better too....more concentrated it seems.
 
That'd be right. Since it's foam it'll mostly be absorbing mids and higher frequencies. Make sure not to deaden your room too much because it isn't absorbing low frequencies. What you can be left with is a room that sounds dead and muddy due to too many uncontrolled lows bouncing around. If you have a lot of it, cram every corner you can, because bass is something you can't trap too much of.
 
Crappy pics but you get the idea.....its really dense and thick.

What are those bass traps/broadband absorbers?

EDIT: Whoops, just scrolled up, nevermind :D Dunno how effective it'll be at bass trappin' though, but if it's thick, decently dense, and is straddling the corners, it'll definintely be better than nothing! Ideally, though, you'd want something more rigid, either rigid fiberglass or rockwool

This stuff is VERY rigid....i could not roll it up if i tried....probably would take alot to fold it in half....its pretty damn dense.

After doing some recording and mixing today, i notice the difference for sure....Everything is just more noticable.....And walking and talking around my house i have the huge echo....and as soon as you walk in this room its DEAD....which is very weird feeling haha. My wife walked in and was talking and immediately stopped cause it felt weird she said hahaha.
 
If I may hijack a bit, I had a room that was fully framed, but no drywall or insulation, and I nailed carpet to the walls. then I threw my bass traps in the corners, and on the walls. they are 4 " thick rockwool traps. It is sounding very good. I imagine that low freqs. are able to pass through the carpet. Any tips on how to improve my room guys?

edit: im also planning on making a cloud over the drumset using carpet. good idea???
 
like has been said, the only way to REALLY know is to check with a reference/calibration mic...run a diagnostic just before putting up the treatment, then immediately thereafter, and compare the results
