Every modern receiver / pre-amp that I have owned uses the -db scale. So with the dial starting at mute, that is -89db. But plaing any source, it seems that I don't start to hear anything until i get to the -40db before the sound becomes noticeable. On an old analog classic receiver, you would hear sound at 1.

This is where the idea of logarithmic comes in as it's not referring to the actual amount of sound coming out the speakers, but the ratio of the amount of turns on the volume knob to the amount of sound. At lower volumes, you seem to need to turn an awful lot to get any sound and that amount of turns seems to decrease in a non linear (logarithmic) fashion as you turn the volume up.
