The Sound of Life
A visual representation of the key people, places and points in time over the course of the invention and development of the hearing aid.
Few inventions have taken such radical changes in shape, function and materials like the hearing aid has. Many of these variations have been affected by other significant inventions –such as the telephone and the carbon transmitter– as well as events such as World War II, which left a countless number of impaired soldiers and catapulted medical research.
This graphic study reflects the evolution and impact of hearing aid devices, looking at the variation in size and acoustic gain over the years, from the first hearing aid device, the bizarre animal wooden ears, to the soundAmp, an iPhone app that collects sound by the microphone, amplifies and processes it in realtime and sends it to your earbuds.
