Pitch is influenced by spontaneous otoacoustic emissions.
Binaural frequency discrimination was studied in musically trained normal subjects. The frequency chosen was that of a spontaneous oto-acoustic emission (SOAE) in one ear. The other ear was free from SOAEs in the test frequency range. Subjective frequency sensation was found to drift away from the frequency of the peak of the emission: Frequencies lower than that of the emission were perceived as being lower than they actually were; frequencies higher than that of the emission were felt to be higher than they actually were (test range, emission frequency +/- 30 Hz).
