Effects of duration of pure-tone frequency discrimination |
These and other findings suggest that a temporal code (phase-locking) is used to code low frequency tones, but that the place code is used to code high frequency tones |
Well, tones are fine, but.. |
The pitch of a harmonic complex |
In fact, if you present the harmonics alone, you still hear the pitch of the fundamental |
