This is exactly the kind of wellness-tech I love: accessible wellness technology. Take a look (or listen) to this NPR report on a new affordable hearing aid that is completely adjustable using your own smart phone or computer. Developed by a Chicago-based company called Sound World Solutions, bring the cost of their assistive hearing device from thousands of dollars down to $299 per ear. While the rest of the hearing aid manufacturers base their strategy on high profits and low yield, SWS uses available technology to produce a high quality product that people can afford.
Hearing loss can be more devastating than many people think. It can be very isolating which affects mood, activity level, and overall health. Furthermore, being cut off socially is probably the last thing someone with mild cognitive impairment or dementia needs.
While the customizable features of this product may be difficult for someone with dementia to manage on their own, it may be a more elegant and useful option to the shrill and uncomfortable sound amplifiers currently available on the market (priced at around $100 per unit).
