Special Episode: Sianna sharing a heartwarming story how hearing aids were invented🦻🏼

Season 1

Sunday, September 21, 2025 • Duration 01:06

Did you know that the first electronic hearing aid in the world was invented because of friendship?

In 1898, an American inventor named Miller Reese Hutchison wanted to help his friend Lyman Gould, who became deaf after getting sick as a child. Even when steamboats made super loud noises, Lyman couldn’t hear them at all.

Miller spent four years studying hearing and invented the very first portable electronic hearing aid, called the ‘Akouphone.’ It used a carbon transmitter to make weak sounds louder—kind of like how a microphone works today! Although his friend still couldn’t learn to speak, Miller’s invention helped him hear more of the world around him.

Fun fact: the invention was inspired by telephone technology, because telephones could already make sounds louder or softer.
