Hello, first-time poster looking for advice on new construction of a dual-purpose mixing room and live room in my unfinished basement.

The room does not exist yet and is in the planning/design phase.

I have some hard constraints on how big it can be.

Primary use for the room is for mixing and recording electric guitars at a reasonable volume. Potential future uses include recording vocals and possibly acoustic drums.

Expected SPL is around 85 dB for a comfortable listening volume for mixing. Could possibly extend up to 95-100 dB for guitar/drum recording.

My primary concern is to reduce audio leakage out of the room vertically to the floor above the basement.
Horizontal leakage to other rooms in the basement is a lesser concern.

Max room dimensions: 154″ x 218″.

The 154″ dimension is fixed; the room exists between a stairwell and a concrete wall.
The 218″ dimension extends between a concrete wall and a dividing regular drywall between two rooms and can be shortened by up to 36″. The adjoining room is not part of the “studio”.

Total height from concrete floor to top of joists is 113″.
Total height from concrete floor to bottom of joists is 101.5″.
Joist height is therefore (113 – 101.5) = 11.5″.

Primary questions:

1) What are the ideal room dimensions that can fit within this max space? 154″ by [182 up to 218]”

2) What are my options for the ceiling? What ideal height to aim for?

3) Is it possible to install sound absorption within the joist area? Or do I install absorbers below the joists?
