Use of ear trumpets begins
1600
The use of ear trumpets for people who were partially deaf dates back to the 17th century. These acoustic devices collected and concentrated sound toward the ear.
Ear trumpets become increasingly common
1775 - 1799
By the late 18th century, the use of ear trumpets was becoming increasingly common as an aid for people with impaired hearing.
Frederick C. Rein begins ear-trumpet production
1800
Frederick C. Rein established the first firm to begin commercial production of ear trumpets in London in 1800, helping turn the devices into manufactured products.
Beethoven uses ear trumpets
1814
Ear trumpets were famously used by Ludwig van Beethoven around 1814 as the composer’s hearing deteriorated.

Rein designs an acoustic chair for King John VI
1819
In 1819, Frederick C. Rein was commissioned to design a special acoustic chair for the ailing King John VI of Portugal.
Hidden hearing aids gain popularity
1875 - 1899
Toward the late 19th century, hidden hearing aids became increasingly popular, reflecting a desire for hearing assistance that was less conspicuous.
Early electric and vacuum-tube aids
The telephone begins the move toward modern hearing aids
1876
The movement toward modern hearing aids began with the creation of the telephone, whose electrical transmission and amplification technologies provided a foundation for later hearing-aid development.

First electric hearing aid is created
1898
The first electric hearing aid was created in 1898, introducing electrical amplification into hearing assistance.
Miller Reese Hutchison creates the Akouphone
1898
Miller Reese Hutchison created the Akouphone in 1898. It was the first electric hearing aid and represented an important transition from purely acoustic devices.
Key Facts
- Early hearing assistance devices included hand-shaped acoustic horns and ear trumpets, which directed sound into the ear without electronic amplification.
- The first electric hearing aids appeared in the late 19th and early 20th centuries after the invention of the telephone made electronic sound amplification possible.
- Vacuum-tube hearing aids became available in the 1920s, but their large size and heavy batteries limited portability.
- The invention of the transistor in the 1940s enabled smaller, lighter, and more reliable hearing aids, including behind-the-ear models.
- Modern hearing aids use digital signal processing, adaptive noise reduction, Bluetooth connectivity, and rechargeable batteries; cochlear implants provide another option for some people with severe hearing loss.
