Presumably the documentation that comes with this mythical
non existent proggie would explain these basic points and
advise the end user how best to set up the tests and apply
any results... and optionally offer to tweak some system
wide EQ settings based on results.

I've had one formal hearing test and I had to step inside
a small booth, close the door, and put on a pair of passive
noise cancelling headphones... took about 15 minutes and I
walked away with a crude printout and another appointment
for the following year. I remember looking at the printout
and thinking "how could I use something like Jamin to master
what I generally listen to according to these results and
automatically apply any compensation?".
