History of Hearing Aids


History of Hearing Aids

1600s & 1700s

During the 1600s and 1700s the “trumpet” style hearing aid was used. As you can see the trumpet had one wide end to gather and amplify sound through the narrow end to direct sound to one ear. Trumpets were made from animal horn, sea shell, glass and later, copper and brass.


1800s

During this era is when efforts to conceal the hearing aid with flesh colors began. Hearing aids were still quite large at this time but were designed to be integrated into collars, head wear and clothing. Royal members had hearing aids built right into their thrones for discretion.

1900s

The advent of electricity introduced a new generation of hearing aids in the 1900s. Electronic amplified sound through a carbon microphone and battery were worn around the neck in boxes containing visible wires. Smaller batteries were created to reduce the size of the hearing aid and a simple switch was added to turn the device on or off.  By mid-1990s hearing aid technology allowed more customization for any user’s lifestyle. Sound could be altered to be amplified, filtered, and reduced when needed in any surrounding.

Hearing Aids Today

Hearing aids today are smaller than ever in a light compact form yet are still powerful and offer complete comfort for the user. They adapt to the change in surroundings and can be streamed through telephones, stereos, televisions and computers to keep up with modern technology. Hearing aids are made in sleek designs with customized options and colors for complete personalization.
