The aim of this study was to compare, in users of bimodal cochlear implants, the performance obtained using their own hearing aids (adjusted with the standard NAL-NL1 fitting formula) with the performance using the Phonak Naìda Link Ultra Power hearing aid adjusted with both NAL-NL1 and a new bimodal system (Adaptive Phonak Digital Bimodal (APDB)) developed by Advanced Bionics and Phonak Corporations.
Eleven bimodal users (Naìda CI Q70 + contralateral hearing aid) were enrolled in our study. The users' own hearing aids were replaced with the Phonak Naìda Link Ultra Power and fitted following the new formula. Speech intelligibility was assessed in quiet and noisy conditions, and comparisons were made with the results obtained with the users' previous hearing aids and with the Naída Link hearing aids fitted with the NAL-NL1 generic prescription formula.
Using Phonak Naìda Link Ultra Power hearing aids with the Adaptive Phonak Digital Bimodal fitting formula, performance was significantly better than that with the users' own rehabilitation systems, especially in challenging hearing situations for all analyzed subjects.
Speech intelligibility tests in quiet settings did not reveal a significant difference in performance between the new fitting formula and NAL-NL1 fittings (using the Naída Link hearing aids), whereas the performance difference between the two fittings was very significant in noisy test conditions.
本研究的目的是比较双模式人工耳蜗使用者使用其自身助听器（按照标准NAL-NL1适配公式进行调试）的表现与使用经NAL-NL1以及由先进生物科技公司和峰力公司开发的新型双模式系统（自适应峰力数字双模式（APDB））调试的峰力Naìda Link Ultra Power助听器的表现。
11名双模式使用者（Naìda CI Q70 + 对侧助听器）参与了我们的研究。将使用者自身的助听器更换为峰力Naìda Link Ultra Power，并按照新公式进行适配。在安静和嘈杂环境下评估言语可懂度，并与使用者之前的助听器以及按照NAL-NL1通用处方公式适配的Naída Link助听器所获得的结果进行比较。
对于所有分析对象，使用采用自适应峰力数字双模式适配公式的峰力Naìda Link Ultra Power助听器时，表现显著优于使用其自身康复系统时的表现，尤其是在具有挑战性的听力环境中。
在安静环境下进行的言语可懂度测试未显示新适配公式与NAL-NL1适配（使用Naída Link助听器）在表现上存在显著差异，而在嘈杂测试环境中，两种适配之间的表现差异非常显著。
