Amazing: 16-Year-Old Invents $60 Hearing Aid!

A 16-year-old student from Louisville has created a device to test and amplify hearing for only $60. DuPont Manual student Mukund Venkatakrishnan worked on the device for two years and has finally completed most of the technological work. He presented the device at the Jefferson County Public Schools Idea Fest and recently won first place the Kentucky State Science and Engineering Fair. Mukund said the processor, which is responsible for amplifying volume by increasing the volume of an incoming signal, was the most expensive part – about $45. Other parts, added up to about $15. He spent hours a day working at FirstBuild, near the University of Louisville campus. Even when the building was closing, Mukund would continue working into the night, weekdays and weekends, whatever it took to complete the device.
