With hearing aids starting out as primitive ear trumpets two centuries ago, the contrast between those and today’s digital models is remarkable. Hearing aids have served so many people in their quest to hear better. To see how far hearing aids have actually come in 200 years, all you have to do is contrast them with today’s hearing aids only weigh a few ounces, providing an unmatched versatility. They offer the user lots more advantages, including the ability to connect to Bluetooth and filter out distracting background noise. Here is a quick look at the history of hearing aids and just how much they’ve advanced.

Revolutionary Advancements

As the 18th century approached, they went through even more advancements. As such, several versions were created for the very wealthy, such as the Reynolds Trumpet. This was personally made for the famous painter Joshua Reynolds, featuring a horn-shaped instrument that basically funneled sound into the inner ear. The ear trumpet was invented back in the 17th century, which were beneficial only to those who suffered from a partial hearing impairment. These were large, cumbersome devices that only served to amplify sound within the immediate environment. Just think of an old phonograph with the conical sphere and you’ll get a good mental picture of what these resembled.

Wearing Them on the Ear

These models had a battery pack that had to attach to the user’s leg which posed obvious imitations. More compact models emerged during World War II for more reliable service to the user thanks to the invention of printed circuit boards.

It wasn’t till the late 1930’s that hearing aids that could be worn on the ear with relative comfort got popular. These devices were made by a Chicago electronics manufacturer, featuring a thin wire connected to an earpiece and receiver.

Unique Possibilities

These were designed to boost the basics of the telephone as well as the electrical signal to improve hearing. The 17th and 18th centuries brought with them devices that offered only limited amplification qualities. This invention was a catalyst for advancement leading to electrical transmission of speech. Thomas Edison was inspired by this invention and came up with the carbon transmitter for the telephone in 1878. When the 19th century came about, electrical technologies emerged spurred on by the invention of the telephone by Alexander Graham Bell in 1876.

Modern Devices

Behind-the-ear models, invented in 1964 by Zenith Radio, featured digital signal-processing chips. Then along came hybrid analog-digital models and then fully digital models by 1996. By the year 2000, programmable hearing aids were on the scene that gave users increased flexibility, customization and comfort. In today’s world, 90 percent of all hearing aids worn by Americans are digital in nature.

Vacuum Tubes

Vacuum tubes, put out by Western Electric Co., came next in New York City in 1920. Manufactures built upon the technology that came from Lee De Forest’s finding of the three-component tube years earlier. They offered not only better amplification but also better frequency. However, they were quite large and not very practical. They got smaller as the years wore on, though, until they got to about the size of a small box. The inconvenience of it all still wasn’t very helpful, plus the comfort level left much to be desired.

Learning from the past, scientists have been able to plow ahead in their discoveries for the future.
