LED Sound Levels! Need Help!

I honestly don't think you should be worrying about any noise from an LED light panel. The noise of the air being sucked from the filter and out the back with mask any noise from a LED panel fan, shiiit, even the general noise from the neighborhood/cars ect will mask it :) Have you considered Plant photonics panels. They are quite literally silent!

Should be pretty close to unhearable at 2-3m distance.
As long as it's really 17 db

yeah but I guess that 2 x 17dB will make it ~~32dB or not actually not sure how would it work

decibel is logarithmic, an increase in 10db makes it 10 times as loud.
So 10db times 10 is 20, something 100 times as loud as 10db is 30db.

2x17db would at most be 20db.
