Table 1.

Means and SD of wave I latency (in ms), and absolute amplitude (in μV) for monaurally stimulated ABRs for ipsilateral and midline electrode montages. Also shown is the number of subjects showing an identifiable wave I for each ear and montage.

For midline montage, monaural waveforms were measured twice, once in each session. If a subject had a wave I value at only one measurement session for a given ear stimulation, that value was used, but if a subject had a wave I at both measurement sessions, the average was used in calculating the mean.
