前言：双峰刺激(BMS)已被证明对语后聋成人的音高排名有好处。然而，对于语前人工耳蜗者使用助听器(HAS)的持续时间而言，非植入耳对音调知觉的贡献仍不清楚。本研究旨在探讨在非植入耳中使用HAS的经历/持续时间是否能改善该人群的音高知觉能力。材料与方法：对29例先天性/语前深度聋儿童进行研究。测试刺激由两个连续的钢琴音组成，范围从C(256赫兹)到B(495赫兹)。结果：使用HAS的时间长短是影响儿童音高知觉正确率的主要因素。音高知觉的总正确率(O)可以通过使用HAS的持续时间(DUA)来预测(O=0.561×DUA，r(2)=0。讨论：使用HAS的经历似乎能提高语前人工耳蜗者的音调感知能力。这表明，在生活早期使用HAS，并通过术后康复计划对植入人工耳蜗术的语前聋儿童进行治疗将是有益的，尽管这种联系不能保证因果关系。需要进行一项纵向研究，以证明使用HAS的持续时间是否可以用听觉诱发电位来衡量这些儿童音乐表现的改善。
Introduction: Bimodal stimulation (BMS) has been shown to be beneficial for the performance of pitch ranking in postlingually deafened adults. However, the contribution of nonimplanted ears to pitch perception with respect to duration of hearing aid (HAs) use for prelingually cochlear implantees remained unclear. This study aimed to investigate whether experiences/duration of HAs use in the nonimplanted ear improved pitch perception ability in this population of subjects.Materials and Methods: Twenty-nine children with congenital/prelingual deafness of profound degree were studied. Test stimuli consisted of 2 sequential piano tones, ranging from C (256 Hz) to B (495 Hz). Children were asked to identify the pitch relationship between the 2 tones (i.e., same, higher, or lower).Results: Duration of HAs use was the major factor related to the correct rate for pitch perception. Overall correct rate for pitch perception (O) could be best predicted by duration of HAs use (DuA) (O = 0.561XDuA, r(2) = 0. 315, p = 0.002).Discussion: Experiences of HAs use appear to improve pitch perception ability in prelingually cochlear implantees. This suggests that incorporation of HAs use early in life and through the postoperative rehabilitation program for prelingually deafened children with cochlear implants would be beneficial, although an association does not guarantee causality. A longitudinal study is needed to show whether improvement of music performance with duration of HAs use in these children is measurable using auditory evoked potentials.
