Electronic & Vacuum Tube Hearing Aids – Early 1900s

At the turn of the 20th century, hearing aids began moving from mechanical to electrical. Borrowing technology from telephone inventor Alexander Graham Bell, the first electrical hearing aid, called the Akouphone – was invented by Miller Hutchinson in 1898.


When did behind the ear hearing aids come out?

How did people hear before hearing aids?

In the 1920s, more electric hearing aids were invented, which used vacuum tubes to amplify sound. However, these were typically fragile and hot, making them not the ideal option for hearing aids. In the 1950s, transistors were introduced to replace vacuum tubes, which made hearing aids smaller and more affordable.

What was the hearing aid in 1920?

In addition to ear trumpets, there were hearing fans and speaking tubes. These instruments helped amplify sounds, while still being portable. However, these devices were generally bulky and had to be physically supported from below.

Are hearing aids better than 5 years ago?

These devices amplified soft sounds more than loud, requiring significantly less volume adjustment. In the last ten years digital processing has greatly improved automatic hearing aid function.

Do any famous people wear hearing aids?

There are noticeable technology advances every three to five years, primarily in processing speed and advances to digital signal processing and noise reduction,” says Collins. For example, the way hearing aids handle background noise and attempt to separate speech from noise is constantly improving.
