Are ear trumpets still used?
Ear trumpets were made of sheet metal, silver, wood, snail shells or animal horns. They have largely been replaced in wealthier areas of the world by modern hearing aid technology that is much smaller and less obtrusive, albeit more expensive.
Who created the ear trumpet?
The device came in a number of shapes and sizes and was made of everything from animal horns to sheet iron. The collapsible ear trumpet was invented next in the late 18th century. The first commercial device was created by Frederick C. Rein in 1800.
How many decibels did an ear trumpet amplify sounds?
With ear trumpets, the amplification amounts to 20–30 dB, the main amplification, however, is in the frequency range below 2 kHz .
How did the Akouphone work?
The first electric hearing aid, called the Akouphone, was created by Miller Reese Hutchison in 1898. It used a carbon transmitter, so that the hearing aid could be portable.

What is the difference between an ear trumpet and a hearing aid?
In the 20th century, ear trumpets were supplanted by electronic hearing aids, which use different techniques to amplify and transmit sound to the user. An electronic hearing aid can be extremely small and the amplification quality is much better than that of an ear trumpet, allowing the user to hear more clearly.
What is a sound trumpet made of?
Ear trumpets were made of sheet metal, silver, wood, snail shells or animal horns. They have largely been replaced in wealthier areas of the world by modern hearing aid technology that is much smaller and less obtrusive, albeit more expensive. A sound trumpet does not “amplify” sound.
