The Eriksholm Collection

The Eriksholm Collection charts the history of hearing aids and hosts a unique collection of mechanical, electrical and electronic instruments.

 

As one of the most complete collections in the world, it provides an impressive overview of the advances in hearing-aid technology over the last century.

 

Two-centuries worth of mechanical devices

In addition to more than 800 historic hearing aids, the collection also contains about 50 different brands of mechanical devices from the US and Europe, dating from 1800 to 1950.

 

The first hearing aid developed by Oticon in 1946.

 

Much more than hearing aids

The Eriksholm collection comprises a great deal of historic documentation. This includes

  • Technical reports and sketches of mechanical designs
  • Descriptions of development processes and technical specifications
  • Sales promotion materials (consumer brochures, product brochures, instructions for use)
  • Photos and audiological fitting guides 
  • Original audio/video tapes, plus DVDs and CD-ROMs containing product information

 

The Oticon Business Archive

The third part of the collection - the Oticon Business Archive - contains documentation from the company’s early years, e.g. ledgers from 1904-1940; business letters from 1920-1950; memos and business plans from the 1950s, and guest books. This archive also contains historic photographs of Oticon locations from all over the world.
