Intra - and intersubject variability of acoustically evoked otoacoustic emissions.
Acoustically evoked otoacoustic emissions are further gaining clinical significance in monitoring cochlear function in adults. It is necessary to consider the intra- and intersubject variability of these measurements prior to interpretation of test results and for clinical implications. Acoustically evoked otoacoustic emission (OAE) measurements were performed in 32 normally hearing adults in three weekly repeated test sessions. Each ear was tested twice per session, and the results were statistically analyzed. All test candidates had measurable OAEs. Statistically significant differences in OAE amplitudes were neither found between two measurements at the same day, nor with weekly intervals. Also, the amplitude differences between right and left ear of the same candidate were not statistically different. OAE amplitudes in women were always higher than in men. These results indicate that monitoring of the inner ear status can be reliably performed using OAE measurements. Changes in OAE amplitudes effectively indicate changes in the cochlear function.
