Attic Shaped Studio

yes, concave peaks will concentrate the energy - which is why locations like peaks, wall-ceilng, wall-floor, and wall-wall corners are excellent places to add absorption as modal supporting energies converge. getting rid of oblique and tangential modes will help even the space - sometimes as much as the main axial modes. in your case, the peak with the notches etc are currently scattering some frequencies and resonating others. filing those will attenuate those and the larger room volume will help slightly.

Thank you George. Yes, the amount of time, work (and sealant!) required for the necessary attention to detail is quite something, it never fails to surprise me even after all those years! It's also a working studio so I have to keep it open as much as possible even during these improvements. Regular clients are fortunately very understanding, some have even been in recently when there wasn't a ceiling

Cheers!

Source of the post I just wanted to peek in and say how inspiring your project has been for the duration. Both in terms of your attention to detail as well as a comfortable dose of reality in terms of the length of time projects like this can take. Thanks for taking all this time to share your journey!

Thanks Glenn, that all makes sense. I'm delighted to report that all that scattering has provided acoustic benefit for a band recording session yesterday, even in this unfinished state. I asked the drummer to setup underneath the raised ceiling. We got a really nice lively sound compared to the usual place at the back of the room, which is drier. Even the bass drum had more of a bloom on it. Nice to have the choice! There was also more space for the other musicians in the room as the drummer could sit next to the side wall rather than having to be some distance from the knee wall at the back of the room.

Cheers!
