Electrocochleography during noise-induced temporary threshold shifts.

The responses of the auditory nerve and brain stem auditory nuclei were recorded non-traumatically in human subjects by means of electrocochleography before, during and after exposure to white noise intensities which produced temporary threshold shifts. The largest decrement (amplitude decrease and latency increase) was seen in the response of the auditory nerve. Large intersubject variability was seen in the effects of the noise exposure on response amplitude, latency and recovery rates.
