Within-subject variability during a hearing aid self-adjustment procedure
What is it about?
This study investigates the variability of participants' preference-based adjustments on hearing aid while they are listening to a speech-in-noise stimulus. The study explores how this variability depends on specific frequency bands being adjusted, and the influence of different user interface design. Results also show that although there is an underlying preference that participants reflect during the self-adjustment procedure, there may be shift in preferences during the procedure.
Why is it important?
This study is timely with the recent rise of self-fitting and over-the-counter hearing aids which may employ certain self-adjustment procedures that allow users to fine-tune their hearing aids. The self-adjustment procedure used in the current study is a unique one that allows analysis of variance and covariance of adjustments across individual frequency bands. In addition, it uniquely allows analysis of effect of user interface on variance and covariance structure.
