| Date/time and place of an event note | Background: Auditory-evoked potentials have proven useful in the objective evaluation of sound<br/>encoding at different stages of the auditory pathway (brainstem and cortex). Yet, their utility for<br/>use in clinical assessment and empirical research relies critically on the precision and test–retest repeatability<br/>of the measure.<br/>Purpose: To determine how subcortical/cortical classes of auditory neural responses directly compare in<br/>terms of their internal consistency and test–retest reliability within and between listeners.<br/>Research Design: A descriptive cohort study describing the dispersion of electrophysiological measures.<br/>Study Sample: Eight young, normal-hearing female listeners.<br/>Data Collection and Analysis: Werecorded auditory brainstemresponses (ABRs), brainstem frequencyfollowing<br/>responses (FFRs), and cortical (P1-N1-P2) auditory-evoked potentials elicited by speech sounds<br/>in the same set of listeners. We reassessed responses within each of four different test sessions over a<br/>period of 1 mo, allowing us to detect possible changes in latency/amplitude characteristics with finer detail<br/>than in previous studies.<br/>Results: Our findings show that brainstem and cortical amplitude/latency measures are remarkably stable;<br/>with the exception of slight prolongation of the P1 wave, we found no significant variation in any<br/>response measure. Intraclass correlation analysis revealed that the speech-evoked FFR amplitude<br/>and latency measures achieved superior repeatability (intraclass correlation coefficient .0.85) among<br/>the more widely used obligatory brainstem (ABR) and cortical (P1-N1-P2) auditory-evoked potentials.<br/>Contrasting these intersubject effects, intrasubject variability (i.e., within-subject coefficient of variation)<br/>revealed that while latencies were more stable than amplitudes, brainstem and cortical responses did not<br/>differ in their variability at the single subject level.<br/>Conclusions: We conclude that (1) the variability of auditory neural responses increases with ascending<br/>level along the auditory neuroaxis (cortex.brainstem) between subjects but remains highly stable within<br/>subjects and (2) speech-FFRs might provide a more stable measure of auditory function than other conventional<br/>responses (e.g., click-ABR), given their lower inter- and intrasubject variability |
