The History of Signia/Siemens Hearing Aids

Werner von Siemens said, “Every day is a new discovery.”  Siemens made a pivotal discovery in 1878 when he designed a telephone utilizing a horseshoe magnet, considerably improving the device’s sound quality. This innovation led to the understanding that the hard of hearing understand the person they are talking to much better if voice signals are amplified.

In the first steps in developing hearing aids, Reiniger, Gebbert & Schall, predecessors to the Sivantos Group, begin building electric audio metersThese produced a ringing sound by means of a special hammer that set magnetic coils into motion.

Siemens hearing aids production begins in Berlin, called the “Esha-Phonophor”.

Over 100 years later, the device can be viewed in Erlangen, Germany, in the medical museum – and it still works!

After the huge success of the first Phonophor hearing aids, Siemens & Halske expanded production activities at Berlin’s Wernerwerk plant. New materials and designs make the Phonophor lighter and more compact while advances in technology improve performance and sound quality.

In the 1930s many people with hearing loss still had to be convinced of the benefits of electric hearing aids. Alongside advertising and partnerships with ear specialists, the salesperson’s training is key. Hearing aid salesmen were predecessors to today’s hearing care professionals, advising people with hearing impairment how to use the new technology.

Early Signia Siemens hearing aid

At the end of World War II, almost all manufacturing plants in Berlin were destroyed or severely damaged. Siemens-Reiniger & Werke, based in Erlangen, became the branch of the company specializing in medical technology. They take over the audiological business in 1945. It does not take long to get their hearing aid business back up and running.

In 1951, Siemens launched the first hearing aids developed and produced in Erlangen, Germany. From then on, hearing aid production increased dramatically. The audiology division grew rapidly while introducing a number of new technologies. 

A new design is introduced: The Behind-The-Ear (BTE) hearing aid.

In 1966, Siemens succeeded in placing a hearing aid completely inside the ear (Siretta 339). A huge step forward in the view of many users.

This was a decade of economic growth, as Siemens began to capture markets in Europe and North America.

“You understand each other better with Siemens hearing aids” was a marketing slogan used by Siemens Hearing Aids in the 70s.

The ’80s were a decade of acquisitions. The purchase of the Rexton and Audio Service hearing aid companies significantly expanded the Signia/Siemens product portfolio.

Signia/Siemens began serving markets in Asia and became a true global market leader.

Following decades of gradual improvements, the 1990s ushered in a new era in hearing aid technology. In 1997, the world’s first completely digital hearing aid with two microphones is launched called “Prisma”.

Unity Computer Programming Software/System was introduced in 1996 allowing for the measuring and adjusting of Signia/Siemens hearing aids using a computer.

The early 2000s was a time of concentrating on traditional strengths and improving internal processes. Signia/Siemens’s most important focus: innovate products.

In 2014, Signia/Siemens introduced another world first: a wireless system connecting hearing aids in both ears to each other. Signia/Siemens hearing aids can now share and exchange audio signals with each other, thereby imitating the natural hearing processes.
