Abstract
The effects of stimulus presentation rate on the various components of the cochlear and early brainstem response were investigated. In one experiment, examining stimulus rates 2 to 20 per second, a significant reduction in peak-to-peak amplitude with increasing rate was found only for the NP, response. In the second experiment, increasing the rate from 12 to 50 per second resulted in a significant decrease in all peak-to-peak amplitudes measured. Increasing the stimulus rate resulted in a significantly increased latency of alt waves except N5. The amount of latency change increased with successive waves.
