DIY Hearing Aid Costs $1 and can Build in 25 Minutes
Researchers at the Georgia Institute of Technology Georgia Tech have developed a hearing aid device that costs as low as $1 and is open-sourced for anyone to build themselves.
The device, known as LoCHAid, is easily manufactured and can be repaired quickly.
The project’s details were published in the journal PLOS ONE on Wednesday.
One of the downsides to growing old is a natural loss of hearing. Sounds become more muffled, with high pitched ones almost disappearing entirely, yet background noises such as traffic and construction become a disturbance.
