Hearing aids are the main intervention for people with hearing loss and have undergone significant digital technology advances over the last two decades. While satisfaction with HAs has improved, users often encounter difficulties in challenging listening conditions (Ohlenforst et al., 2017). The hearing aids hashave limitations. Disadvantages of hearing aids include that they don’t block out background noise, they don’t separate speech and noise in noisy environments, and they don’t allow people to hear sound at a distance (Ohlenforst et al., 2017). For this reason, many specialists recommend auditory and cognitive training. Thus, the current AC training has implications for people's clinical management with a decline in auditory and cognitive processing. The AC training changed brain structure in the DLPFC, and the ITG relates withto working memory and auditory processing, respectively. Additionally, the AC training change FC of the IFG and STG regions correlates with attention and auditory perception. We believe that this study has implications for improving auditory and cognitive training in older adults. Moreover, the findings reported here show a new method tofor training auditory and cognitive processes simultaneously. This method can be benefitedbeneficial mainly infor the elderly, who hashave declined auditory and cognitive abilities. Additionally, our auditory training method can improve auditory sensitivity and change brain structural and functional connectivity.
