Comparison of Hearing Aid Fitting Outcomes Between Self-fit and Professional Fit for MDHearing Smart Hearing Aids

Comparison of Hearing Aid Fitting Outcomes Between Self-fit and Professional Fit for MDHearing Smart Hearing Aids

Hearing aids are commonly used to help people with hearing loss hear better in daily listening environments. MDHearing Smart hearing aids are designed to use the MDHearing app to adjust hearing aids to each individual's hearing loss. This study intends to show whether the MDHearing Smart hearing aids can be fitted by each user reliably and if each user can use the MDHearing app on their smartphone or tablet to make adjustments to achieve good aided benefit, which will be compared to those fitted by audiology professionals. This study includes three components: human factor study, self-fit study, and professional-fit study. The information obtained will be useful for both audiology professionals and people with impaired hearing.
