Hi John, thanks for sharing your precious knowledge with us here!
We are building a studio in a 150yo house with wood floor on wood-beams. ( rock wool under the beams for insulation from the garage).
-What would be a good solution to treat/ avoid exciting the floor? In order to level it up, we planned a 5cm layer of dry cork grains, and an OSB floor floating to it. dry floating floors.
-I was also curious about your “vented floors” design under the console at Rue Boyer. Have you done that anywhere else? We would be tempted to do it but it’s a pretty bold move!
Congrats on the Rue Boyer design by the way, hoping to visit soon!
Best

That sounds like it will work - density is what you are going for. Use glue if you can and nail. When you are cross seaming - don’t have seams on top of each other - We have had some good luck with plywood - 2 layers of 5/8" gyp board and then final layer of plywood - make a very tight floor on 12’ spacing - fill void with some kind of insulation.
We have done this once or twice before, We use very advanced custom software (BEM - boundary element method) to determine a kind of heat map for sorting out very specific LF pressure positions (go to REDIacoustics.com) . Turns out that a location that is optimum for LF absorption at specific low frequencies is often directly above or below the listening position. We are rarely able to get the opportunity to introduce a resonator below the mix position chair! At Rue Boyer, we were able. We did a similar treatment at Church Studios in London.
that’s very cool! thanks for both reply. We will then definitely go ahead and build over the old wood floor and beams, here is the “sandwich”:
-studio
-wood flooring ( or cork finish)
-new solid OSB floor, 100 % floating on screeds, no nails ( or gypse)
-2" dry screeds made of expanded cork (or clay balls)
-old wood floor nailed on
-wood Beams
-insulation projected underneath the beams.
-garage
I will look into REDI Acoustics right now. Thanks a lot!
