Physiological, Behavioural and Subjective Measures of Listening Effort
Switzerland17 participantsStarted 2018-10-08
Plain-language summary
Participants will perform two different listening tasks: (1) listening to, and repeating back, sentence lists presented in noise, and (2) listening to short radio excerpts and answering subsequent comprehension questions. At the same time participants are required to perform a manual target-tracking task on a touch screen. During this study, continuous, non-invasive physiological measurements (heart rate, skin conductance and hemoencephalography) will be made from participants. Using this paradigm we will be assessing the effect of different hearing aid processing algorithms on listening effort. The study takes the form of a three factor (listening task x algorithm x signal-to-noise ratio), within-subjects design. Each participant performs each listening task (about 4min long each) with each algorithm (reference, noise reduction I, noise reduction II), at two signal-to-noise ratios (+4 decibel and 0 decibel) twice (test-retest).

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
