How exactly do our eyes and ears work logarithmically?

Question

I’ve always heard that the decibel scale for hearing is logarithmic, and I’ve recently learned that our eyes view and compare objects logarithmically as well. How exactly does this process work, and is it different between the eyes and the ears?

Answer 1

1 lion and 2 lions look very different.

99 lions and 100 lions look about the same.

The difference in still one lion, but one lion matters less when there’s already 99.
