I disagree here. While recording practice does specify a standard
level, mistakes happen -- extra dynamic range allows for a greater
margin of error when out in the field at 4am, in the dark... Also,
what about recording something like a thunderstorm, or a passing train
(not nature I know). There are definitely times when that extra
dynamic range is a great asset.
So for me it's not about the ability of the ear to discriminate, but
the tendency of the brain to make mistakes....
