目的：本研究的目的是调查年龄对听力努力的影响。方法：使用双任务范例来评估不同背景噪声条件下的听力努力。包括 60 名年龄从 20 岁到 77 岁不等的成年人。主要语音识别任务和辅助记忆任务分别和同时执行。使用多元回归分析来评估年龄和听力阈值如何影响语音识别和听力努力得分。结果：多元回归分析的结果表明，年龄是听力努力的重要决定因素，即使语音识别中与年龄相关的方差被部分排除，听力努力也会随着年龄的增长而增加。根据回归方程和听力努力中位数得分，发现听力努力在四十岁开始增加。 结论：这项研究是对从年轻人到老年人听力努力的首次探索，结果表明，与听力敏感性无关，听力努力随着年龄的增长而增加。更具体地说，需要进一步研究对言语交流很重要的认知功能，同时探索它们与听力努力之间可能的关系。
Purpose: The objective of this study was to investigate the effect of age on listening effort.Method: A dual-task paradigm was used to evaluate listening effort in different conditions of background noise. Sixty adults ranging in age from 20 to 77 years were included. A primary speech-recognition task and a secondary memory task were performed both separately and simultaneously. Multiple regression analyses were used to evaluate how age and hearing thresholds affect speech recognition and listening effort scores.Results: Results of the multiple regression analyses showed that age is a significant determinant of listening effort, whereby listening effort increases with increasing age even when age-related variance in speech recognition is partialled out. On the basis of the regression equations and the median score for listening effort, it was found that listening effort started to increase in the fourth decade of life.Conclusions: This study was a first exploration of listening effort from young to older adults and showed that, independent of hearing sensitivity, listening effort increases with age. To be more specific, there is a need to further investigate the cognitive functions important for speech communication while exploring their possible relationship with listening effort.
