Abstract

Objective: Previous studies have already documented improved speech intelligibility and music performance with the use of Nonlinear Frequency Compression (NFC) but as it is widely acknowledged that hearing aid users may gain increasing benefit with longer experience it is interesting to look into long-term effects of this technology. Speech perception benefit with extended use of NFC has been reported for children and cochlear implantees showed a significant improvement in melody recognition after extended use. Aim: The purpose of this study was to determine the long term effect on the perception of music with NFC in adult hearing aid users and whether speech intelligibility in noise changed with extended use of NFC. Design and Sample: As real-life use and experience of NFC hearing aids is necessary to reveal its true potential, the study described in this article was performed roughly three years after the initial study to address any long-term aspects and therefore a comparitive research design was implemented. A subgroup of the participants (n=9) of the study described in Uys, Pottas, Vinck and Van Dijk was recruited to check for their music performance and speech intelligibility after 3 years’ experience with NFC. Results and Conclusion: The results confirm the general observation of increased benefit from the hearing devices when making use of the high-frequency cues provided by NFC. Whereas the majority of parameters describing the subjective perception did not change, those parameters relating to the performance - especially melody identification and speech understanding in noise - did improve over the longer period. This leads to the conclusion that it is prudent to intensify the evaluation into the long-term effects of NFC technology.
非线性频率压缩对音乐表现和语音感知的长期影响
目的:先前的研究已经记录了使用非线性频率压缩(NFC)可以提高语音清晰度和音乐表现,但由于人们普遍认为助听器用户可以通过更长的经验获得更多的好处,因此研究这项技术的长期影响是很有趣的。长期使用近距离通信对儿童的语音感知有好处,耳蜗植入者在长期使用后显示出旋律识别的显着改善。目的:本研究的目的是确定成年助听器使用者使用近距离通信对音乐感知的长期影响,以及噪音中的语音清晰度是否随着近距离通信的延长而改变。设计和样本:由于NFC助听器的实际使用和体验是揭示其真正潜力的必要条件,因此本文中描述的研究是在初始研究后大约三年进行的,以解决任何长期方面的问题,因此实施了比较研究设计。在Uys, Pottas, Vinck和Van Dijk所描述的研究中,研究人员招募了一组参与者(n=9),以检查他们在使用近距离无线通信3年后的音乐表现和语音清晰度。结果和结论:研究结果证实了使用近场通信提供的高频信号时,听力设备带来的益处增加的普遍观察。尽管描述主观感知的大多数参数没有改变,但那些与表演有关的参数——尤其是在噪音中识别旋律和理解语音——在较长时间内确实有所改善。由此得出结论,加强对NFC技术的长期影响的评估是谨慎的。
