Speak Up! The History Of Hearing Aids

As long as there have been human beings, there have been those who couldn’t hear as well as others. Long ago, most reasons a person couldn’t hear usually was due to injury or illness. Very few people made it past 30. When people were able to get old enough to go deaf due to age and not trauma, then the history of hearing aids began.

Trumpets And Horns

The hand cupped behind the ear was likely the beginning of the history of hearing aids. Technically, the outer ear is shaped like a cupped hand, trapping sound and channeling it to the organs that actually do the hearing in the inner ear. But the hand cupped behind the ear brings the sound even more directly to the ear. Once that was figured out, then the history of hearing aids made specifically to amplify faint sounds began.

The first made hearing aids were most likely seashells, hollowed out animal horns or tubes of bark. The first ones were most likely quite fragile, and it took centuries of trial and error before sturdier ones could be made. When they were made of metal or flexible tubing, they were shaped like trumpets and bells. Sometimes it looked as if the deaf person was putting an oversized pipe in his or her ear.

The history of hearing aids is about making sounds louder than they probably really are. Some of the oldest surviving hearing aids are from the 1700’s. One of the most famous users of a hearing aid trumpet was the great composer Beethoven, although it did not prevent him from becoming completely deaf.

Not much changed in the history of hearing aids during the 1800’s, except that the horns looked more like musical horns or ram’s horns than a pipe. A popular hearing aid of the time was called the London Dome and came in many sizes and outer ornamentation.

Changes

About 1899, the most advanced hearing aids in the world ran on carbon batteries. They looked a bit like the first telephones, large and with a lot of wires. The batteries usually lasted only about twelve hours. The whole contraption was worn as a large necklace. Even an electric version that came out in the 1920’s did little to improve things.

The real turning point in the history of hearing aids came in the 1950’s with electric transistor hearing aids. Now hearing aids were smaller, lighter and more reliable. As their name implied, they worked using the same technology of transistor radios.

In 1984, digital technology produced the latest wave of hearing aids.
