20db is .25 times less loud if we're talking about sensed/perceived volume. If 60 db, the equal of a normal conversation from about a yard away is reduced by 20 db it's about the same as a quiet library. I am not an acoustician* nor an engineer; I don't do the math. these are from charts found at educational sites for sound and music engineering. I avoided numbers because of this. My post was to illustrate that there are thin forms of sound isolation solutions. I've used all of the ones I cited in my home studio except for green glue which wasn't widely available at the time .

Kurt

We do have at least on acoustician on the board. His name doesn't come to mind at the moment

I'm not sure Kurt's numbers are correct, a 6 dB decrease is half volume. Thus 60 dB decrease in sound is 1/2096 as loud. While the ear may be quite sensitive there's a reason there's a measurement called RT60. That's the time it takes reverberation to decrease by 60 dB, a 60 dB decrease is basically inaudible to humans (unless you begin with a very loud sound, the result may still be audible but soon thereafter won't be).

To the OP congratulations on making your decision. I'm sure you'll love your Estonia.
