This is going to sound pretty weird, I'm sure, but could as many people
on-list perform the following experiment on themselves and their close
ones, as possible? Then report back (privately, so as not to ruin the
surprise for everybody else?)
Take a long (at least 30 seconds and possibly more) sequence of truly
random (AWGN) noise, either from a very long period PRNG or from a
primary randomness source. Then starting with very long periods of over
10 seconds, loop the noise, curtailing the period of repetition.
Dropping it, say, 200ms at a time at first, and in the end perhaps
something like 10ms at a time. When does your ear, perceptually
speaking, start to say that the noise repeats? Precisely?
I'd be interested in hearing what people on-list have to say about this
one. Especially the ones who are curious enough to find the precise
limit in milliseconds, and even subject their loved ones to the test.
Because, I mean, at least for me this was a total mindfuck, and if you
analyze it e.g. via the usual LTI theory of human hearing, the results
do not make any sense at all. I think, but I'm not too sure. Whence
the question. ;)
