Setting the MacOSX volume really low

I just realized it took me insanely long to figure this out and never put it up here in case someone else had the same problem. I have this theory after using original Apple earphones once that they use a preresistor that is just way to big and once you plug something decent in then you just go deaf even on the lowest level of the volume slider.

I then quickly found out about option-shift- but that only gets you down to 2.5% of the volume which is still quite loud in a quiet place. The lowest i have found out how to get to is 1% (and even that is too loud in the library sometimes) and this is how you do it:

#!/bin/sh
osascript -e "set Volume 0.01"
