The goal of this investigation was to determine the potential benefit of using electromagnetically coupled frequency modulation (FM) neck-loop receivers to address common communication difficulties of adults and adolescents with cochlear implants (CIs).
Fourteen participants with CIs used the neck-loop FM receiver for a trial period and participated in pre- and post trial sessions consisting of speech-recognition-in-noise measures with and without the FM system and a subjective rating scale. Most participants also recorded their experiences during the FM-system trial period in a journal.
The results suggested significantly improved speech recognition in noise with the neck-loop FM system before and after the trial period, with no changes in performance between test sessions. On average, the rating scale and journals revealed improvements with the FM system, relative to the CI alone, in noisy environments or situations at a distance from the primary talker or sound source.
The results of the study suggest that neck-loop FM receivers significantly improved speech recognition in noise and everyday listening challenges of people using the CIs in 2 separate test sessions. Additional research is warranted for other types of neck-loop receivers and CI sound processors.
本研究的目的是确定使用电磁耦合调频（FM）颈圈式接收器来解决成人和青少年人工耳蜗（CI）使用者常见沟通困难的潜在益处。
14名人工耳蜗使用者在试验期使用颈圈式FM接收器，并参加了试验前和试验后的测试环节，包括有和没有FM系统时的噪声环境下言语识别测试以及主观评分量表。大多数参与者还在日记中记录了他们在FM系统试验期的经历。
结果表明，试验期前后，颈圈式FM系统在噪声环境下的言语识别能力显著提高，测试环节之间的表现没有变化。平均而言，评分量表和日记显示，相对于仅使用人工耳蜗，FM系统在嘈杂环境或与主要说话者或声源有一定距离的情况下有改善。
研究结果表明，在两个独立的测试环节中，颈圈式FM接收器显著提高了人工耳蜗使用者在噪声环境下的言语识别能力以及日常聆听能力。对于其他类型的颈圈式接收器和人工耳蜗声音处理器，还需要进行更多研究。
