How can you say that a sinusoid of 5 kHz elicits a perception of pitch? You cannot make pitch-matching experiments with harmonic complexes as references in this range. At 5 kHz there usually is no longer a perception of pitch chroma. This effect of "frozen chroma" is commonly taken as sign that the pitch extractor is no longer functional. Also, such stimuli never occur in natural sounds. Therefore our hearing is not adapted to them. I see no reason why the percept a sinusoid of 5 kHz can be called pitch. I suggest that you tell your students to call the percept a percept of timbre.
