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.
Perspectives
This manuscript is particularly interesting by analyzing the data obtained from a strong applied research together with earlier findings from basic science. The study employs unique statistical analysis techniques that are rarely used in audiology, which readers may find particularly intriguing. The methodology employed in the study involves two slightly different experiments to validate and corroborate the findings across distinct experimental settings. The nearly year-long publication process allowed for substantial refinements, resulting in a manuscript of heightened quality.
