P.P.S. Another little question: do you know of a similar
graph with the limit of audibility of pre-echo (ore
pre-ringing, or whathever it is called)? Something like
limit of audibility with respect to pre-delay vs level
and/or frequency?

I believe that the phrase you are looking for is "temporal
masking".

Here's a fairly classic item about it:
