No. In the norm, the higher-frequencies (moving hair cells in the
front of the cochlea) are perceived as higher-pitched, while
lower-frequencies (moving hair cells at the back of the cochlea) are
perceived as low-pitched.
If this was reversed it would be interesting. Lower-frequencies would
be higher-pitched and higher-frequencies would be lower-pitched.
A cassette played at higher speed than recorded while sound abnormally
low-pitched. If played at a lower speed than recorded, it would sound
Faster vibrations would be lower-pitched and slower vibrations would
I always wonder what it would be like.
On my MIDI keyboard when I play a higher note for a tone instrument
(e.g. an accordian) I feel the vibration to be faster. When playing a
lower note, I feel the vibration to be slower. If the "pitch
receptors" in my cochleae were switched, I would feel the higher-notes
to vibrate slower than the lower-notes. Right?
