Does this help with room acoustics?

I often see the dropped border around the perimeter of home cinema ceilings.
I am near to completing the construction of my dedicated room which will mean I am ready to fit it out and plaster etc. I'll be using acoustic panels, bass traps and diffusers as shown in my model here

But I'm wondering if the dropped perimeter helps somehow or is it just to add character and lighting / to frame starlight ceilings etc?
I feel pretty stupid as a professional builder not knowing the name lol but here is a photo of what I mean!!





Thanks for any input.

If you build the soffits inside the sound isolation wall design it becomes an excellent place for recessed lighting, duct work and wiring that doesn't require cutting holes that compromise your soundproofing efforts. Depending on your design you might also integrate a projector hush box for a cleaner look.

Thanks, it would certainly be something like in your image above if I did it however I think it would only be if it improved room acoustics rather than sound isolation / proofing as the ceiling I plan to do will already be a suspended and decoupled 'false' ceiling below the sound proofed real ceiling.



In the video I linked it shows the bass traps at the back of the room, would the soffit have any positive impact on room modes etc?

I doubt it. As BIG said, most of the time soffits are used in basement theaters to "hide" obstructions such as ducts, and pipes, as well as a excellent place for lighting, etc. Others do it as you mention as an architectural feature for lighting, star ceilings, etc.

7.4.4 Theater Room: JVC-RS500, Silver Ticket AT 2.35:1 142”, Onkyo RZ830, Anthem PVA-7, Panasonic UB420, Apple TV 4K, JBL Studio 530’s, Dual Driver VBSS

3.1 Living Room: Samsung 64” F8500 Plasma, Anthem MRX 300, Dynaudio Audience 52’s, Dynaudio Audience 122C, NHT SubOne, Roku Express (2019)
