- 1. Hearing Aids over the Years Nowadays, whenever we think of hearing aids we picture a tiny device hidden behind the ears, responsible for amplifying sound waves in order to help people with hearing disabilities. However, what we don’t know is that they weren’t always that tiny or compact. Over the years, hearing aids have evolved and gone to major changes. 17th century The first hearing aids, known as ear trumpets, were made during this period. These are tubular devices, made out of metal, silver, wood, shells or animal horns that collect sound waves and lead them to the ear. Back then, people hid these devices in their fans, canes and jewelries to avoid being ridiculed by their peers. 18th century The invention of the telephone had a great impact on the evolution of the hearing aid because they use almost the same kind of technology. The first hearing electric hearing aid, called Akouphone, was created around 1898 by American electrical engineer Miller Reese Hutchison. It was later manufactured by a company called Siemens. One major flaw with the Akouphone is its design, as it is big, bulky and not portable. 19th century World War II’s military technology has helped in the development of hearing aids. This gave inventors the idea of miniaturization. By this period, hearing aids were created small enough to fit hand bags. In this period, transistors, which also played in the advancement of hearing aids, were also invented. The first vacuum hearing aid was made in the 1920s, while the first digital hearing aid was created in the 1960s. 20th – 21st century Through today’s modern technology, hearing aids have become a lot more advanced than its previous versions. They are now equipped with power microchips. What’s more, they are also waterproof and can last a lot longer. Visit Ledesma.com.ph for more info and help you to know more.
