Brief Summary:
Participants will perform two different listening tasks: (1) listening to, and repeating back, sentence lists presented in noise, and (2) Subjective rating of effort \& performance following each condition. During this study, continuous, non-invasive physiological measurements (skin conductance, changes in pupil dilation) will be recorded 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 one factor (algorithm), within-subjects design.
Each participant performs the Speech perception task with each algorithm (reference, noise reduction I, noise reduction II, noise reduction III), at two individualized signal-to-noise ratios (SRT90 and SRT50). Additionally subjective performance ratings in real-life will be collected.
