IME when the action is WAY too low, the string rattles against the frets... slightly different , but analogous, to fret buzz. If the "arc of string vibration" is reduced, it can only be reduced because the string is impacting the frets at some point (which I would assume to be the midpoint of the vibrating string length) . This impact is going to have an audible effect other than the mere reduction of volume.... it cannot be otherwise. IMO, any reduction of volume resulting from lowered string height is down, purely and simply, to less torque on the bridge. A vibrating string doesn't care how far away the frets are ... it does react to the height above the soundboard at the bridge. |

That assumption would be incorrect, the max deflection would be the same distance from the nut(or fret if fretted) as the original pick point was from the saddle. It's actually two waves going in opposite directions on the string.
