My two cents as a person in the field:
the human hearing system is kind of an LTI... only at very low level
processing. The consistency of measured signal (= perceiving the same
signal the same way at all time as somebody wrote here) is present in
the ear canal up to brainstem - inferior
As someone already pointed out, spend an evening to hack a website for this.

don’t.

If there, by chance, happens to be a feature in the noise that
catches the ear and creates a sort of (possibly first subconscious)
memory, then the choo-choo effect will be more audible as that feature
can be more easily recognized again, reinforcing the memory. I

It may be fine to think of the ear as doing a Fourier transform as a first,
crude approximation. For a more accurate description however, some nonlinear
effects would have to be considered. And some of this already happens in the
ear.
As for hearing being LTI, think about forward and backward

Yes.
So if we have N digital poles, can we create N digital zeros at the
same frequencies, convolve those two filters and arrive at a digital

Small correction:
the correct name is MM5837, which is a 16 bit shiftregister device. It’s bad
but can be replaced by the MM5437, a 23 bit device which can be clocked
externally and has a much longer period.

It doesn't react in a linear fashion to frequency or loudness, but it

the same signal the same way at all times, disregarding aging, hearing

One of the easiest ways to see that hearing must be nonlinear is

So in the digital sense, or in combination with the analog domain,
is it reasonable to think about correctable operations, which as

*and* it's converse, we end up with the same signal or something similar.
