No, it's a ratio; a value measured in dB. As such, it implies a resolution,
namely the number of divisions it makes sense to divide (quantize) the range
into.

No. Dynamic here is meaning 4. in Random House "4. of or pertaining to the
range of volume of musical sound." Dynamic ranges are basically volume
measurements; that is, a dynamic range is a ratio of volumes, loudnesses,
or, more generally, signal amplitudes.
