Abstract :

Hearing care professionals and hearing aid manufacturers still report untenable levels of remakes, returns for credit, and
cases of failure to fit for a variety of reasons. Hearing aid discomfort, own-voice artifacts, and cost/benefit perceptions
top the list of reported reasons. In the present study, the status of the keratin or corneum stratum in the external auditory
canal (EAC) has been found to negatively or positively affect hearing aid adaptation. These include keratin’s role in preventing
oversensitivity in EAC mechanoreceptors (hair follicles, Meissner corpuscles and Pacinian corpuscles) and their subsequent
neuroreflexes (Arnold’s Branch, Trigeminal, and Lymphatic Reflex), which affect own-voice perception, insertion and removal,
wearing comfort, and coupler adaptation.
