Hi Ethan, Thank you very much for your recent helpful feedback on acoustic panel construction regarding burlap being sufficient to trap OC 703 flakes.
I'm about to start the build on my new mix room, which is a rented space in a quiet industrial building that otherwise houses visual artists' studios. My space is surrounded for the most part by voids (hallways). The walls are sheetrock, some parts of which resonate at sub frequencies when bumped with the heel of one's hand and bleed occasional noise from foot traffic in the halls. The space is smaller than you recommend for a mix room and generally not "ideal," but it has many advantages and I'll make the most of it for now.
It has been suggested to me to start by covering the walls with 4'X8' sheets of 3/4" MDF (chipboard), to deaden the low-freq resonance of the walls, reduce a little of the bleed, and provide an easy uniform surface to mount cleats for hanging the acoustic panels, etc.
My question is, do you think the MDF is a good idea? My only concern is that it would somehow deflect more bass back into the room, but I will be covering almost all of the wall surface with OC 703 acoustic panels, soffits, a few diffusers, etc., which presumably will trap any interference the MDF may add.
Thank you again for your extremely helpful insight and generosity.
Best, kj

I think a better approach is to use blow-in insulation to fill the walls. I assume that, being interior walls, they're not insulated. If this is true and the walls are just drywall on studs with air in between, filling the air space with insulation will probably help more than adding mass. Though adding mass could possibly be useful as a second step. The type of blow-in insulation I mean is similar to fluffy fiberglass. Not Styrofoam, which is good for thermal insulation but not for sound proofing or controlling resonance.
