The transiently evoked otoacoustic emission amplitude of 42 preterm babies (84 ears; post-conceptional age [PCA] 30-36 weeks) was compared with the TEOAE amplitude of 39 full-term babies (78 ears; PCA 37-45 weeks) in order to trace the inner ear maturation characteristics. An ILO-92 otoacoustic emission recording system was used with linear clicks of 70 dB peak equivalent SPL. The results obtained indicated: (1) There was no statistically significant difference between preterm and full-term ears; (2) There was no significant difference between males and females; (3) There was a significant difference between left and right ear TEOAE amplitude; (4) The interaction of ear with age in relation to TEOAE amplitude was statistically significant; (5) Noise and stimulus parameters did not reveal any significant differences between right and left ears; (6) A positive correlation existed between birthweight and TEOAE amplitude; and (7) A negative correlation existed between aminoglycoside treatment and TEOAE amplitude. The results indicate subtle changes in TEOAE amplitude over time, showing a natural development of the inner ear function during the process of maturation.
为了探寻内耳成熟特征，比较了42名早产儿（84耳；孕龄[PCA]30 - 36周）的瞬态诱发耳声发射幅度与39名足月儿（78耳；PCA 37 - 45周）的TEOAE幅度。使用ILO - 92耳声发射记录系统，采用峰值等效声压级为70 dB的线性短声。获得的结果表明：（1）早产儿耳和足月儿耳之间无统计学显著差异；（2）男性和女性之间无显著差异；（3）左耳和右耳的TEOAE幅度存在显著差异；（4）耳与年龄在TEOAE幅度方面的交互作用具有统计学显著性；（5）噪声和刺激参数在右耳和左耳之间未显示出任何显著差异；（6）出生体重与TEOAE幅度呈正相关；（7）氨基糖苷类药物治疗与TEOAE幅度呈负相关。结果表明TEOAE幅度随时间有细微变化，显示出内耳功能在成熟过程中的自然发育。
