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.
Conditions
Interventions
| Type | Name | Description |
|---|---|---|
| DEVICE | Hearing Aid without NR enabled | Each participant will be fitted with noise reduction disabled. Disabled means that no sound processing algorithm that removes noise from the speech signal is active. |
| DEVICE | Hearing Aid with NR(1) | Each participant will be fitted with the noise reduction program on the same hearing aid. The principle of the noise reduction algorithm is to remove noise from a speech signal with the aim of improving the speech intelligibility and comfort. |
| DEVICE | Hearing Aid with NR(2) | Each participant will be fitted with a second noise reduction program on the same hearing aid. The parameterization of this NR algorithm differs from that in NR(1). |
| DEVICE | Hearing Aid with NR(3) | Each participant will be fitted with a third noise reduction program on the same hearing aid. The parameterization of this NR algorithm differs from that in NR(1) and NR(2). |
