Auditory nerve responses to short bursts of acoustic noise have been recorded by gross electrodes. For moderate stimulus intensities the amplitude of the response is independent of burst repetition rate for rates below approximately 10/sec. The curve of response amplitude vs rate then decreases except for a small “bump” in the curve near 600/sec. Synchronized responses were detected for repetition rates as high as 3000/sec by an average response computer. These data have been considered in terms of a model that accounts for the overlapping of the response waveforms. In terms of this model, the neural activity decreases monotonically with increasing rate above the rate 10/sec.
