The effect of contralateral acoustic stimulation on transient evoked otoacoustic emissions (TEOAE) was used to investigate the functional maturity of the medial efferent olivocochlear system in full term neonates and a 6-week-old baby. The technique used was to record the TEOAE alternately with and without contralateral noise. The result was a reduction in TEOAE amplitude and latency. This was best illustrated with a difference waveform obtained from the subtraction of the TEOAE waveform recorded with contralateral noise, from the waveform recorded without contralateral noise. All the full term neonates and also the 6-week-old baby showed significant effects indicating functional maturity of the medial olivocochlear system.
对足月新生儿和一名6周大婴儿，采用对侧听觉刺激对瞬态诱发耳声发射（TEOAE）的影响，来研究内侧传出橄榄耳蜗系统的功能成熟度。所采用的技术是在有和没有对侧噪声的情况下交替记录TEOAE。结果是TEOAE的幅度和潜伏期降低。从没有对侧噪声时记录的TEOAE波形中减去有对侧噪声时记录的TEOAE波形得到的差值波形，能最好地说明这一点。所有足月新生儿以及这名6周大婴儿均显示出显著效应，表明内侧橄榄耳蜗系统功能成熟。
