I'll try to skip the rambling and get straight to the details. I have a dedicated HT that is nearing completion. Here's a link to my build thread in case you're interested
. I contracted both Erskine Group (originally) and Nyal Mellor of Acoustic Frontiers (final design) to do the acoustic treatment plan, and I have already purchased the treatments spec'ed by Nyal, but have not installed them yet.
I would like to get a comprehensive set of before, during, and after measurements of my room as I go from untreated to fully treated. This seems like an area where there is very little information available on the boards (at least I haven't see it if it does exist). My treatment plan includes both DIY absorption and engineered panels for diffusion, so this should be more useful in understanding the benefits (if any) of engineered treatments as opposed to just narrow/broadband absorption.
The problem: I have no experience measuring and tweaking an acoustic space. If I'm going to invest the time to measure this in pieces rather than just install all my treatments and go from there, I'd like to make sure I do it so that the community gets the most value from it. To do that, i will need some guidance from those of you more experienced in order to make sure I'm measuring things correctly as well as to develop a strategy for adding the treatments in the correct order.
Finally, I expect this to move rather slowly. My HT is my hobby, and there are a lot of other things in my life that take priority. So I only have so much time I can put into it each day. Fortunately, the hardest part is done. That is, I have the room, I have (most) of the equipment, and I already have ALL of my treatments available. So it really comes down to finding time to actually install a portion of the treatments followed by measuring the results.
Here's how I'd like to lay out the opening posts.
Post 1 - Introduction (you've made it through that part already)
Post 2 - Layout of my room and my acoustic plan
Post 3 - Testing strategy (I need a lot of help with this!)
Post 4 - Results (how did each set of treatments impact the space?)
Post 5 - Conclusions (what did we learn? Anything we can improve on? Was it worth it?)
