Rock and other participants in this subject forum,
Firstly Rock, my room is only for 2 channel pure listening. And I do now, understand that a "slightly dead" room will produce pleasing sound. Unfortunately I still feel something is still missing in the acoustics of my room.
I can say I have learned a lot and like you said experience is the key and as I progress my understanding of even the little things have extremely improved. So I hope my continuous posts, which help me, can help others from understanding their projects from earlier stages.
You guys will be happy to know I have bought tools for REM, Behringer microphone, and the necessary soundcard. My next project will be to learn to use REW.
But in saying that I have come to a few conclusions which I will share and any help would be greatly appreciated!
1. If you have a close look at my pictures provided, you'll see a hallway/opening to the front right-hand side. I have covered it with a panel as that area is a reflection point. But in saying that, and correct me if I am wrong, that a hallway at the front part of your room will put your room acoustics out of balance and more importantly be a factor in liveliness as that room will produce echo. So I am in process of totally covering that.
2. I ordered a bunch of fabric samples from Guilford of Maine and ATS acoustics. They range from very breathable burlap to really aesthetically cool looking material that is not so breathable from Guilford of Maine. I attempted the Ethan sound test which you speak into the fabric over foam. And I did some other various tests comparing my foam, ATS cotton panel with my DIY mineral wool panel with the material on top. I also compared reflection coefficients from Guilford of Maine between breathable materials to the not so breathable materials to understand better what is going on with the reflection of the highs in conjunction with its breathability. No doubt that breathability corresponds to reflecting less high frequencies. My conclusion is that although I feel burlap is significantly better than my fabric used, when I compare some of the Guilford of Maine fabrics which are not so breathable they are on par with my material chosen for my panels, the only difference being that mine is slightly thicker. To be honest my fabric is more breathable than some of the Guilford of Maine fabrics. So ultimately the liveliness might not be from my fabric used? I am willing to reupholster side panels but I'm curious if changing it to burlap or even Guilford of Maine fabrics would make such a difference especially if Guilford of Maine fabrics are reflecting highs like my fabric used. But burlap, is an option, definitely reflects less high's compare to mine and some of the Guilford of Maine fabrics. Confusing I know... Any opinions? Have I got it down pat or gaps exist in my conclusion? Ultimately would the breathable burlap make a difference i f change the upholstery of my panels?
3. I might just need to cover more of the room with panels especially panels that absorb higher frequency.
Regards
