Abstract

OBJECTIVE

This paper provides a detailed description of the Nucleus 6 system, and clinically evaluates user performance compared to the previous Nucleus 5 system in cochlear implant recipients. Additionally, it clinically evaluates a range of Nucleus 6 and Nucleus 5 programs to determine the performance benefits provided by new input processing technologies available in SmartSound iQ.

DESIGN

Speech understanding tests were used to clinically validate the default Nucleus 6 program, by comparing performance outcomes against up to five custom Nucleus 5 or Nucleus 6 programs in a range of listening environments. Clinical comparisons between programs were conducted across the following listening environments; quiet, speech weighted noise (co-located and spatially separated noise), and 4-talker babble (co-located and spatially separated noise).

STUDY SAMPLE

Twenty-one adult cochlear implant recipients participated.

RESULTS

Significant speech understanding benefits were found with the default Nucleus 6 program compared to the participants' preferred program using their Nucleus 5 processor and compared to a range of custom Nucleus 6 programs. All participants successfully accepted and upgraded to the new default Nucleus 6 SmartSound iQ program.

CONCLUSION

This study demonstrates the acceptance and clinical benefits of the Nucleus 6 cochlear implant system and SmartSound iQ.

摘要

目的

本文详细描述了 Nucleus 6 系统，并对人工耳蜗植入受者使用该系统与之前的 Nucleus 5 系统相比的用户表现进行了临床评估。此外，还对一系列 Nucleus 6 和 Nucleus 5 程序进行了临床评估，以确定 SmartSound iQ 中可用的新输入处理技术所带来的性能优势。

设计

通过在一系列聆听环境中，将性能结果与多达五个定制的 Nucleus 5 或 Nucleus 6 程序进行比较，使用言语理解测试对默认的 Nucleus 6 程序进行临床验证。在以下聆听环境中对程序进行临床比较：安静环境、言语加权噪声（共置和空间分离噪声）以及 4 人交谈嘈杂声（共置和空间分离噪声）。

研究样本

21 名成年人工耳蜗植入受者参与了研究。

结果

与使用 Nucleus 5 处理器的参与者首选程序以及一系列定制的 Nucleus 6 程序相比，默认的 Nucleus 6 程序在言语理解方面具有显著优势。所有参与者均成功接受并升级到新的默认 Nucleus 6 SmartSound iQ 程序。

结论

本研究证明了 Nucleus 6 人工耳蜗系统和 SmartSound iQ 的可接受性及临床优势。
