Pitch perception break-point at 170 Hz ?

Subject: Pitch perception break-point at 170 Hz ?

Dear readers of the list:

In speech pitch data (fundamental frequency f0) I found preliminary evidence that the human auditory system may process pitch < 170 Hz differently from pitch > 170 Hz. The effect was independent of sex.

Question: Has anybody come across or heard of results, either psychoacoustical or physiological, that may be relevant to a possible break point in human pitch perception at ~ 170 Hz ?
