Proof-of-concept for a new ultra-low-cost hearing aid for age-related hearing loss — ScienceDaily

A new ultra-affordable and accessible hearing aid made from open-source electronics could soon be available worldwide, according to a study published September 23, 2020 in the open-access journal PLOS ONE by Soham Sinha from the Georgia Institute of Technology, Georgia, US, and colleagues.

While the price to manufacture hearing aids has decreased over time, the retail price for a pair of hearing aids ranges from $1,000 to $8,000
