Ive got an S9 under my desk at home and the noise is fine if you heavily underclock it. Mine is running 5.8Th with ambient temps of 20c and fans set to 25%. The PCB and Chip Temps are 62c and 90c respectively.
I do have a manually adjustable S9 though. New ones have "autotune" which doesn't let you adjust the freq or the fan speed, which is important is you want to make it quieter.

Not knowing your $/KWh, does this under clocked rate (5.8 Th vs, 13-14 Th) still make running just one (S9) miner profitable? (say ROI of less than 8-12 months?)
Isn't your noise reduced/manually reduced setting just above an S7 mining rate?
All that being said (asked), my rigs ambient would probably be just be slightly above yours (+/- 74f ; 23c). If I build/purchase an enclosure for noise abatement, I would exhaust the air outside of my home (either to garage or up my dryer exhaust vent).
