Abstract：
UNASSIGNED: The study investigated how auditory training affects effort exerted by hearing-impaired listeners in speech-in-noise task.
UNASSIGNED: Pupillometry was used to characterise listening effort during a hearing in noise test (HINT) before and after phoneme-in-noise identification training. Half of the study participants completed the training, while the other half formed an active control group.
UNASSIGNED: Twenty 63-to-79 years old experienced hearing-aid users.
UNASSIGNED: Higher peak pupil dilations (PPDs) were obtained at the end of the study compared to the beginning in both groups of the participants. The analysis of pupil dilation in an extended time window revealed, however, that the magnitude of pupillary response increased more in the training than in the control group. The effect of training on effort was observed in pupil responses even when no improvement in HINT was found.
UNASSIGNED: The results demonstrate that using a listening effort metric adds additional insights into the effectiveness of auditory training compared to the situation when only speech-in-noise performance is considered. Trends observed in pupil responses suggested increased effort-both after the training and the placebo intervention-most likely reflecting the effect of the individual\'s motivation.

摘要：
■该研究调查了听觉训练如何影响听力受损的听众在噪声中语音任务中所付出的努力。
■在噪声音素识别训练之前和之后，在噪声测试（HINT）中使用瞳孔测量法来表征听力。一半的研究参与者完成了培训，而另一半则组成了一个主动对照组。
■二十名63至79岁有经验的助听器使用者。
■与两组参与者的开始相比，在研究结束时获得了更高的瞳孔扩张峰（PPD）。在延长的时间窗口中对瞳孔扩张的分析显示，然而,训练中瞳孔反应的幅度比对照组增加更多。即使没有发现HINT的改善，也可以在瞳孔反应中观察到训练对努力的影响。
■结果表明，与仅考虑噪声中语音性能的情况相比，使用听力努力指标增加了对听觉训练有效性的更多见解。在学生反应中观察到的趋势表明，训练和安慰剂干预后的努力增加，最有可能反映出个人动机的影响。
