简要总结
Participating in spoken conversation constitutes a multitasking situation with concurrent demands on sensorimotor (auditory, postural) and cognitive functioning (memory, updating, task switching and inhibition). As aging affects multisensory integration and cognitive control, these higher-order processes are likely to put accumulating constraints on listening as adults grow older. By training listening skills (not solely auditory skills), the investigators aim at improving overall communication and quality of life. Moreover, the investigators aim at freeing up cognitive resources in the listen task: the better one gets at a certain domain specific task, the less one needs to draw from other resources and, the more resources are free for another concurrent task. The interdisciplinary approach will inform us about ideal audiological rehabilitation or intervention approaches. Pre-posttests comprise behavioral measures to evaluate listening skills and transfer towards non-trained measures. The training is tablet-based and can be performed at home.
详细描述
Goals of the study:
- Investigate transfer of listening skills to non-trained listening.
- To develop evidence-based guidelines for clinical audiological rehabilitation.
- Investigate if the inclusion of cognitive control frees up cognitive resources to use for another concurrent task.
- Inform about retention following listening training
All participants will be assessed 4 times, with a 4-week interval in between. Participants in the first arm will perform the training during the first two weeks. 4 weeks after training ended and 8 weeks after training ended, retention of training gains will be assessed. Participants in the second arm will perform the delayed training. This is to control for procedural learning effects. After 4 weeks they will start training for 4 weeks. After training retention of training gains will be assessed after 4 weeks. The third arm will start with active control training (listening to stories) for 4 weeks, followed by training for 4 weeks. After these 8 weeks, retention was measured 4 weeks later. Participants are randomly allocated to a group. The efficacy of training will be determined with a within-subject design (i.e. baseline session outcomes will be compared to the final session outcomes of the randomized control trial.

结局指标
主要结局
phoneme identification in noise
时间窗: 12 weeks
The consonant identification task in noise consisted of 12 Dutch/Flemish vowels presented in an /a/ context. Stimuli were produced by a female speaker. In order not to obtain 100% at the start, stimuli were presented in speech-weighted noise.
Speech in noise intelligibility
时间窗: 12 weeks
LIST (Leuven intelligibility sentences test) sentences presented in speech-weighted noise. Participants are required to repeat sentences in noise. The Leuven Intelligibility Sentences Test (LIST) was specifically designed for speech perception in noise assessment in CI users. The test has high test-retest reliability and a steep slope making it very sensitive to small improvements in performance. An improvement of 2dB results in a clinically relevant improvement in speech discrimination in noise. Therefore, the primary endpoint to validate the active training will be an improvement of 2dB on speech perception in noise.
