I bet that makes for an interesting audible change in the room's acoustics. Looks good!

Thanks Fred. I must have a terrible ear because I tried listening for a difference between before and after and between left and right and I couldn't discern any difference. I have not watched a movie in there since adding the knauf to the rear wall but I did play music. Maybe once I get the whole wall complete and pop in a movie that I have watched before I will be able to hear an improvement.

I have not. Anything in particular that I should be listening for? Less sound bouncing around the room?

I need a crash course in ear training...

It might be hard to hear. Clapping is good enough to hear flutter echo, which is a nice and easy place to start. When flutter echo is bad, you'll hear a "zing" or "sproing" sort of tail to the sound. If you can't make that out in the theater, that's fine and good. Try clapping in a stairwell or parking deck. I'm of the opinion that flutter echo is just the beginning and the only thing you'll be able to identify by clapping, but I suspect others disagree (Nightlord). He may have a way for you to hear more spectral details of the decay, but I don't have a lot of faith in that.

Another easy way for you to begin to hear differences and the effect of the absorption is to stand right up next to it; one ear to it and the other out into the room. Get a simple recording playing - especially one without a lot of processing or ambiance added, or just get a conversation partner - and listen carefully, paying attention to the differences betwee what each ear hears. Stand next to untreated wall, and then move in front of the treatments.

Being able to hear subtle changes takes practice. I'm not good at it, but I'm working on it.

Nope, not in clapping, you described that perfectly.

Other thing to try is standing right up to the wall and listen to/feel yourself talk.

We were just discussing finding if there's any differences. Any more detailed stuff I'd say you need to measure for.

Thank you both for the information. I will give those suggestions a try the next time I am down there while hopefully finishing off the back wall.

Minor update - This weekend I found a few moments to finish my back wall insulation and plastic. I also added four of the vertical green panels that I had complete but just sitting around.

Pics showing the 4 mil plastic stapled over the 6" of knauf insulation.






And now with the four new green panels added.






And a new overview shot of the back of the theater.


I still have two green panels to install on the sides and then I will be ready to start making some new panels to fit between all of these. Slow progress but it's still progress I guess...

Hi Vanice, I have been reading through your thread and watching your progress eagerly, as well as "borrowing" construction tips along the way. I see that you and I are both following Bryan Pape's acoustical strategies.

I am stumped though on my soffit, as I have the similar problem as you had for sectioning off the soffit to box in the HVAC duct and allow the rest of the soffit to be open for wire runs and recessed lights.

I can see how you constructed the HVAC boots and plan to follow that idea. How did you finish off from the HVAC boots back to where the HVAC duct enters the room? Do you have any closeup photos? Thanks for any more detail you can provide!!!

Vanice- your build thread is intimidatingly impressive! Perhaps builds like yours prevent me from posting my "basic" first build. (lol) I do have a question though. Early on in your thread your were using the Graco 2600 paint sprayer. However, i noticed later that you were using a good ole' fashioned paint roller and pan. What was your experience with the sprayer because I am considering using it?

Thanks for the compliment! Just wish it was a completed build thread.

Several reasons. With drywall primer I knew that I was going to have to get a lot of paint on since new drywall sucks paint up like a sponge. I probably would have had to back roll it anyway so I just decided to roll from the beginning. The ceiling might have been a good spot to try spraying but I hadn't used the sprayer to this point and I was worried about how it would come out having to thin the paint properly and lay down even coats. I knew I wanted to get this part right so experimenting here wasn't for me. I could have used it on the MDF column pieces but those were kinda sporadic in finishing so setting up the sprayer several different times didn't sound fun. But it's not all bad. I did finally use the sprayer in other parts of my basement to spray trim/baseboards and doors. In this case the sprayer saved me a ton of time. Thinning the paint takes some practice, the sprayer can kick up a little dust if your not careful, and you end up with a fine mist of paint in the air that eventually settles to the floor creating a light coating (so cover things that you don't want messed up) but for large areas and places you want a nice smooth finish is does very well. Tape up some paper on a wall to test the spray before you get going and you should be fine. I haven't used it a ton but I already feel like I got my moneys worth out of it and I see plenty of future projects were it could come in handy. Hope this helps. Let me know if you have any more questions about it.

Vanice- Thanks. I may go ahead and get the sprayer for a professional look on the ceiling and the walls. I appreciate your input. Keep persistant and keep up the good work!
