You didn't make it clear in your previous post that it was actually the
auditory testing centre that tested your ability to differentiate
between waveforms at 14KHz. I don't doubt that their equipment is both
capable of this level of performance and of uncompromising quality.
This does imply that you can sense 28KHz components in the sound, which
is a rather super-human ability. Have you ever been in the presence of
an old ultrasonic remote control and been annoyed by it? Can you hear
the squeal from ultrasonic proximity detectors? Those woofer stopper
things that emit ultrasonic noise to quieten noisy dogs must drive you
mad too!
