摘要
该研究旨在通过设备编程减少耳蜗间频率和响度失配,改善单侧耳聋(SSD)人工耳蜗(CI)受者的预后。在实验1a中,为了更好地匹配对侧耳的张力性,减少耳间频率失配,我们创建了一个改进的频率分配表(FAT)。20名有经验的SSD-CI用户用他们的日常FAT完成了本地化和语音识别测试。使用改良FAT 6周后重复测试。参与者将两种脂肪进行了两周的比较,然后再次进行测试。对于10例新植入的SSD-CI受体(实验1b), A组使用制造商默认的FAT编程,B组使用激活时修改的FAT编程。每个FAT使用6周后完成语音识别和定位。然后参与者在测试前比较两种脂肪。在实验2中,15名经验丰富的SSD-CI用户使用他们的日常程序和修改的响度程序进行评估,该程序旨在获得0.25至6 kHz范围内约20 dB HL的可听性和耳朵之间的平衡响度。进行了三次测试,类似于实验1a。实验1a和实验2中经验丰富的参与者在使用修改后的程序时,与日常程序相比,在一项噪音语音任务中表现出显著的改善。新植入的受体在两种脂肪之间的结果没有显著差异。结果表明,修改程序,以减少内部不匹配,可以改善结果。在激活后的第一个月比较脂肪可能为时过早,因为SSD-CI接受者正在适应电听力。
Improving Outcomes of Single-Sided Deaf Cochlear Implant Users by Reducing Interaural Frequency and Loudness Mismatches through Device Programming.
The study aimed to improve outcomes in Nucleus cochlear implant (CI) recipients with single-sided deafness (SSD) by reducing interaural frequency and loudness mismatches through device programming. In Experiment 1a, a modified frequency allocation table (FAT) was created to better match the tonotopicity of the contralateral ear and reduce interaural frequency mismatch. Twenty experienced SSD-CI users completed localization and speech recognition tests with their everyday FAT. Tests were repeated after 6 weeks' use of the modified FAT. Participants compared both FATs for 2 weeks before being tested again with each. For 10 newly implanted SSD-CI recipients (Experiment 1b), Group A was programmed with the manufacturer's default FAT and Group B with the modified FAT at activation. Speech recognition and localization were completed, after 6 weeks' use of each FAT. Participants then compared both FATs before testing with each. In Experiment 2, 15 experienced SSD-CI users were evaluated with their everyday program and a modified loudness program, which was created to obtain audibility of ∼20 dB HL from 0.25 to 6 kHz and balanced loudness between ears. Three test sessions occurred, resembling Experiment 1a. Experienced participants in Experiments 1a and 2 showed significant improvement in one speech-in-noise task with a modified program compared to the everyday program. Newly implanted recipients showed no significant difference in results between FATs. Results indicate that modified programs, created to reduce interaural mismatches, may improve outcomes. The first month after activation might be too early to compare FATs as SSD-CI recipients are adjusting to electric hearing.

期刊介绍:
Trends in Hearing is an open access journal completely dedicated to publishing original research and reviews focusing on human hearing, hearing loss, hearing aids, auditory implants, and aural rehabilitation. Under its former name, Trends in Amplification, the journal established itself as a forum for concise explorations of all areas of translational hearing research by leaders in the field. Trends in Hearing has now expanded its focus to include original research articles, with the goal of becoming the premier venue for research related to human hearing and hearing loss.
