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.
If you have any antique hearing aids, historical documentation, pictures of hearing aids or people wearing them - or any piece of Oticon-related historical information - we would be delighted to hear from you.

Did you know this?
Hearing aids from the 1920s often still work! Their components haven’t deteriorated as much as newer hearing aids containing rubber and foam rubber, that stiffen or crumble with time.
What did hearing aids cost in 1910, 1920, 1930 and 1940? An extrapolation of the old prices into current prices yields the following results (in USD): $5000, $2700, $1600 and $3250 respectively.
