Effect of Noise Reduction Algorithms on Physiological, Behavioural and Subjective Measures of Listening Effort
Effect of Noise Reduction Algorithms on Physiological, Behavioural and Subjective Measures of Listening Effort
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).
