title: Frequency composition of spontaneous cochlear emissions.
abstract: Spontaneous cochlear emissions consist of one or more sinus tones. Oscillations and frequency shifts clearly widen averaged traces. Multiple peaks, if present, are spaced at intervals of 2-3% of the frequency, and increase with frequency. A frequency jump by the same amount was seen in one case. This appears to represent the distance between hair cells, and suggests that individual hair cells play a leading role in these oscillations.
