Solve an Old Problem with a New Idea

Can you think of a solution to a problem that’s been around for a long time?

Alexander Graham Bell spent many years trying unsuccessfully to develop some way to help the deaf communicate. The knowledge he gained from his work eventually led to the invention of the telephone in 1875.

Miller Hutchinson, inspired by Bell’s telephone, developed a battery-powered hearing aid in 1902. Although large and bulky, it worked much like a telephone and quickly replaced the ear trumpet. Later, with the development of transistors and small batteries, hearing aids were made small enough to fit inside the ear.
