In particular, hearing aids are designed to maximize the ability to hear
and understand the human speaking voice. Anything outside of that is
normally filtered out. Even within that range the sound will not
necessarily be reproduced evenly.

I would agree here. It's the sort of thing here where that info should
be fairly easy to obtain as the hearing aids are custom designed to
match the particular person's hearing.

I suppose it depends on the hearing test. The ones I did when in the
military covered from 50Hz to 8KHz and that was just a simple survey one
to see if you were qualified to be sent off to be shot. More
importantly, to hear orders, and the other warfare sounds you needed to
hear. The self test system I have here covers all the way to 20KHz with
many steps along the way. Though without calibration using a good sound
meter that one will not give you accurate absolute sound levels, but
only relative.
