“Loop current†would be measuring the DC component of what is found on a phone line. Georg Ohm figured out the directly proportional (linear) relationship of voltage and resistance back in the early 1800’s.
A voice signal transmitted over a copper wire is a sinusoidal waveform (AC) positioned on top of the DC component. So now if you meant the “voice signal†that is measurable in decibels, is a non-linear (logarithmic) scale, that would in fact be true.
I think I’ll stand by my concern, since in this case, it would seem an attenuator of any kind would be masking a symptom rather the correcting the issue.
