| Summary: | The literature has reports on the influence of spontaneous otoacoustic emission (SOAE) on transiently evoked otoacoustic emission (TEOAE), but most do not take factors such as age, gender, and hearing level into consideration. We focused on these conditions. Subjects were 78 women with normal hearing aged 19 to 24 years (mean = 21.4). All had pure tone thresholds of 15 dB HL or better at 1 kHz, 2 kHz, and 4 kHz. ILO88 was used to record TEOAE and SOAE. Echo power (EP) and reproducibility (Repro) were compared between groups with and without SOAE. No significant audiometric difference was seen between groups. Total echo power (TEP) and whole reproducibility (WR) were significantly greater in the group having SOAE, consistent with previous reports (p < 0.01). EP and Repro classified by frequency bands were also significantly greater in the group having SOAE at 1 kHz to 4 kHz. Subjects were divided based on the number of SOAE and the above parameters compared. We found that as the SOAE number increased, EP and Repro increased. In conclusion, the existence of SOAE influences TEOAE parameters and must be taken into account during clinical testing. |
