I don't know if I've understand correctly what you mean, but I try to
reply :)

Because our ears just work like that.
But I think there are only a metter of visualization. For example,
complression curves are often reprented using dB scale. So that,
straight line correspond to a straight "feel" to our ears.
With that in mind, one could represent amplitude envelope just like
that. The problem here is that an amp envelope can be 0, that means
minus infinite dB -> the scale of the graph must be "mapped" in order to
suite clear visualization.

Cheers
