From Human Need to Smart Technology

Hearing well has always been essential for communication, relationships, and feeling part of the world. But the journey to restoring hearing has not been easy.

From the first animal horns used to amplify sound to today’s sophisticated digital hearing aids, the history of these devices is, in fact, the story of the fight to stay connected.

This journey is not only about inventions, but about the human will to keep listening and actively participating in life.

The First Attempts to Amplify Sound (before the 17th century)

Centuries before hearing aids existed, humans had already devised ways to improve hearing.

The earliest references come from civilisations that used natural objects like sea shells, animal horns or metal tubes to channel sound towards the ear.

In Greece and Rome, the use of acoustic horns or funnels during speeches or theatre performances was documented. These tools were not true hearing aids, but they represented an early step in understanding acoustics and the need to assist human hearing.

The First Mechanical Hearing Aids (17th – 19th centuries)

The true starting point arrived in the 17th century, with the invention of ear trumpets, considered the first recognised hearing aids.

These were conical tubes made of metal, wood or ivory that concentrated sound and directed it into the ear canal. Despite their simplicity, they significantly improved speech perception in quiet environments.

In the 18th century, ear trumpets became popular among the upper classes and well-known historical figures, such as Ludwig van Beethoven, who used several models after partially losing his hearing.

During the 19th century, smaller and more discreet versions were developed, such as folding trumpets or devices built into walking sticks or furniture, demonstrating the creativity of the time.

The Arrival of Electricity: The First Electric Hearing Aids (1900 – 1930)

The 20th century changed everything.

With the discovery of electricity and the development of carbon microphones, it became possible to actively amplify sound.

One of the pioneers was Miller Reese Hutchison, who in 1902 invented the Akouphone, considered the first portable electric hearing aid. It ran on batteries with a small amplifier and marked the beginning of a new era.

Although these devices were bulky and expensive, the improvement in sound quality was revolutionary for the time.

The Era of Vacuum Tubes and Miniaturisation (1930 – 1950)

Vacuum tubes improved sound amplification and quality, but required power and took up space. The first portable models consisted of a control box connected by a cable to an earpiece.

From the 1940s onwards, with the miniaturisation of components, hearing aids began to shrink in size and become more discreet. This enabled wider adoption, especially after the Second World War, when many soldiers with hearing damage needed technological support to regain hearing.

Transistors and Modern Hearing Aids (1950 – 1980)

With the arrival of the transistor in 1947, hearing aids made a huge leap.

These components replaced vacuum tubes, reducing power consumption and device size.

This led to the development of behind-the-ear (BTE) hearing aids and later in-the-ear (ITE) models, which were much more comfortable and aesthetically pleasing.

During the 1970s and 80s, improvements in frequency response and automatic volume controls were introduced, allowing better adaptation to different environments.

Digital and Smart Hearing Aids (1990 – Today)

By the late 20th century, hearing aids had fully entered the digital age.

Digital signal processing made it possible to analyse and filter sound in real time, eliminating noise and improving speech clarity.

Moreover, advances in computing and microelectronics led to increasingly small, efficient and customisable devices.

Today, hearing aids can connect to mobile phones via Bluetooth, store listening environments and even self-adjust depending on movement or the direction of the voice.

They are the result of centuries of innovation with a single goal: to restore the natural ability to hear.

Conclusion: A Story That Keeps Evolving

The history of the hearing aid is a fascinating journey that combines human need, technological ingenuity and scientific progress. From the first ear trumpets of the 17th century to today’s smart digital devices, each advance has marked a step forward in how we hear, understand and connect with the world.

Modern hearing aids, such as those from Oticon, are the result of this constant evolution: devices capable of adapting to our surroundings, improving speech comprehension and reducing the mental effort involved in listening.

Today, hearing technology not only helps restore sound, but also preserves auditory and cognitive health, helping us stay active, communicative and connected with life.

The history of the hearing aid does not stop.

Every new generation of devices represents another step towards a future where hearing better means living better.
