How much aborbtion can one typically expect after treating a room (bass traps, primary reflections)?
I was planning on recalibrating my studio this afternoon, as I notice that the calibrated levels I had been using before treatment are now too low.
Upon measuring, it appears that I've lost approx 15dB (using pink noise, C weighted slow response).
5dB I've accounted for (upgraded my DAC with lower output than the previous one), but should superchunks and some Rockwool bring down the overall level by 10dB?
I'm asking because I wonder if there isn't something else going on that I simply haven't noticed while I was busy getting set up for measurements this afternoon.
Cheers,
Thor
