Hearing Loss and
Relationship between hearing loss and cognitive function,
how DNN supports the brain?
Firstly, the degraded sound quality exacerbates listening efforts and hence, strains the thinking and memory system. Secondly, hearing loss causes the aging brain to shrink more quickly. Thirdly, the increased communication difficulties undermine individuals’ social life, thereby reducing intellectual stimulation from people interaction. If hearing loss is left untreated, not only one’s daily functioning is hindered but may also lead to cognitive decline.
As alleviation, studies showed that hearing aids help with certain extent of brain recovery, in turn, reducing the likelihood or delaying the development of dementia. To understand this better, we shall start by discussing how we listen and how the brain makes sense of sounds. The subsystems ‘orient’ and ‘focus’ in the brain allow us to form and select sound with minimal effort.
