[LAU] Calculating absolute played(!) volume

Hey hey,
for a project I am wondering, if the absolute output volume of a pair of 
headphones, directly connected to a soundcard, can be gained from the 

I have a Delta 1010. Inside alsamixer the volume for the DACs is set in dB. Is 
there a straight relationship between these settings and a connected output 
device? My pair of headphones, IIRC, have a resistence of 60 Ohm.

Any help is appreciated. A good pointer will do. If there is a method without 
special measuring equipment, I'd be happy. If not... So be it.

Best wishes,
