A cross-sectional, experimental, and randomized repeated-measures design study was used to examine the objective and subjective value of telecoil and hearing loop systems. Word recognition and speech perception were tested in 12 older adult hearing aid users using the telecoil and microphone inputs in quiet and noise conditions. Participants were asked to subjectively rate cognitive listening effort and self-confidence for each condition. Significant improvement in speech perception with the telecoil over microphone input in both quiet and noise was found along with significantly less reported cognitive listening effort and high self-confidence. The use of telecoils with hearing aids should be recommended for older adults with hearing loss.

采用横断面、实验性和随机重复测量设计研究，以检验感应线圈和助听环路系统的客观和主观价值。在安静和嘈杂环境下，使用感应线圈和麦克风输入，对12名老年助听器使用者进行了单词识别和言语感知测试。要求参与者对每种环境下的认知聆听努力程度和自信心进行主观评分。结果发现，与使用麦克风输入相比，在安静和嘈杂环境下，使用感应线圈时言语感知均有显著改善，同时报告的认知聆听努力程度显著降低，自信心增强。对于有听力损失的老年人，建议使用带有感应线圈的助听器。
