At least, this is my rudimentary understanding of the concept.

Maybe I'm misunderstanding you. Are you saying that a reduction of 1/5 of measured db equates to about a 1/4 reduction in perceived loudness of the individual?

I understand that human hearing is logarithmic in nature (able to differentiate volume of quiet noises effectively while differentiation of loud noises is harder), but I'm not sure I quite follow your statement.
