Sound Quality Ratings While Streaming Primary · 60 minutes

Hearing aid recordings of different coupling options will be presented via a Multiple Stimuli with Reference and Anchor (MUSHRA) paradigm, where participants will rate and compare sound quality attributes between them. Ratings will be made on a scale where 0 would the minimum value and 100 would be the maximum value. Fullness: Higher scores indicate that participants found the recording to be fuller (thicker/richer sound). Higher scores indicate a better outcome. Sharpness: Higher scores indicate that participants found the recording to be sharper (thinner/more shrill). Lower scores indicat

Situational Preference Ratings Secondary · 60 Minutes

Hearing aid recordings of different listening situations through different coupling options will be presented via a Multiple Stimuli with Reference and Anchor (MUSHRA) paradigm, where participants will indicate preferences between different recordings. Ratings will be made on a scale where 0 would the minimum value and 100 would be the maximum value. Higher scores indicate increased preferred sound quality. Higher scores will indicate that participants had an increased preference towards that recording when compared to the other recordings. In this measure, on
