@joenies thank you, I will check into those. I was initially looking at triangle shaped but those were all listed as bass traps which I don't think is the right solution.
Do you think the panels you describe would be run along the entire 13' wide beam?
I am obviously a novice at acoustic treatments as I usually have enough in the way of window, floor, and furniture soft treatments to aid my cause.
Acoustic treatment for odd ceiling issue
I moved into an older home which has a random architectural feature in the ceiling. I've attached a photo to give you some perspective but here's the details.
This protrusion is 13' long and 12" wide and it is located in the ceiling between the audio setup (speakers more specifically) and the seated position. I've got decent treatments on floor, windows, and walls but I'm hearing reflections, echo like sounds in the upper frequencies which I never heard in my previous home setup.
I've looked at 12" x "12 self adhesive acoustic panels that seem like they would help and I was thinking of running 12' along the protruding section itself and anther 12' run along the ceiling, forming a 90 degree angle of acoustic tile so to speak.
I am not sure that is the right approach and would love to hear from the community.
Thanks!

@dbagstrick If I understand you correctly the ceiling "box" runs across the room width and is between the speaker plane and your listening chair, is this correct? If so, then you may be hearing flutter echoes that are caused by reflections off the ceiling box on either side of it (e.g. off its back side closest to your speakers and front wall, and off its front side visible from your chair). I'd say you're on the right track of attaching absorption (4" thick preferably) along its front and back vertical surfaces. How far down from the ceiling does the box extend? If it's about 17-24" you could use a triangular shaped bass trap to fit snugly into the corner made by the box and ceiling. Depending on what your room's decay times are you could opt for absorption on the back side of the box as seen by the speakers and diffusion on the front side seen by you from your chair. |
@kevinzoe Thank you! You are correct, my seat is approx 3' behind the box area. |
