We operate globally with a local presence through our companies in more than 30 countries and through trusted distributors in more than 130 countries. This way, we combine the best of two worlds: centralised and standardised processes that value local presence and initiatives.

Adding to our global orientation is a local presence. As a company represented in many countries, we act as a good citizen in the community. Besides from expected compliance with rules and regulations, this good citizenship includes the ambition that our employees and products contribute positively to the development of the community.

Demant covers five business areas: Hearing Care, Hearing Aids, Hearing Implants, Diagnostics and Communications.

We are the only company in the world that covers these five areas, and we harvest significant synergies from this unique position. Synergies that will help millions of people experience the joy of hearing for many years to come. Just as the Demant family envisioned it when they founded the company in 1904.

With our approach to hearing healthcare and technology, and our complete product range, Demant, our customers and partners are fully equipped to help people with various kinds of hearing loss and communication needs connect with the world and live their lives to the fullest.

Our unique position is a great advantage in a market that is growing. The hearing healthcare market represents a value
of around USD 24 billion per year, with Europe and North America being by far the largest markets. Global tracking of hearing loss, e.g. MarkeTrak, EuroTrak and JapanTrak, shows that around 1 in 10 people over the age of 50 is living with a hearing loss, and more than 18 million hearing aids and 85,000 hearing implants are sold every year.

The estimated value growth rates are 2-4% in the hearing aid market and 10-15% in the hearing implants market. This growth is largely driven by the underlying demographic development and, particularly for hearing implants, gradually increasing penetration rates. The estimated value growth rate in the diagnostics market is 3-5%.

The Communications market represents a value of around USD 6 billion, and the estimated value growth rate is around 12%.

William Demant Foundation is a commercial foundation which main purpose is to secure and expand the commercial activities of Demant A/S and William Demant Invest and to donate money to charitable causes.

Demant was founded in 1904. Back then, Hans Demant had a good reason for doing so: His wife Camilla suffered from a severe hearing loss, and Hans was determined to help her and others in a similar situation. From personal experience, Hans Demant knew about the complex psychological problems that people often experience when they have difficulty communicating.

In 1910, after his father passed away, William Demant took over the business and quickly proved to be an energetic businessman. He was both a visionary and personally engaged in treatment of hearing loss, and in 1957, he created William Demants og Hustru Ida Emilies Fond. The foundation was established to ensure that the company would continue as a business based on humanistic philosophy. Today, this foundation is known as William Demant Foundation.

William Demant Foundation's statutes declare that income must be used to support the needs of people with hearing loss as well as relevant organisations. The Foundation’s income derives from its investment under William Demant Invest.

William Demant Foundation sponsors social and educational programmes, publications, conferences, cultural activities and campaigns for researchers, hearing care professionals and the general public.

Eriksholm - design size - 960x700

Eriksholm Research Centre pursues audiological discoveries with the potential to significantly enhance user benefits in future hearing care. Research is carried out in close collaboration with academic research institutions, clinicians and people with hearing loss. Being part of Oticon ensures that the scientific insights are applied in solutions which empower people with hearing loss.

Eriksholm Research Centre is located in Helsingør, 50 km from Demant's headquarter. The location away from the company´s headquarter facilitates the mind-set and working environment necessary for carrying out good long-term and in-depth research, but at the same time, there is a constant flow of people and ideas between Eriksholm and the headquarter.

A very broad spread of topics is being investigated at Eriksholm, well organised under three strategic, mega-trend inspired research themes: Cognitive Hearing Science, Social Hearing Science, and Augmented Hearing Science.

Eriksholm engages in close collaboration with academic research groups from all over the world, and the vast majority of Eriksholm's research is published and presented at academic conferences. This reflects the fact that the researchers at Eriksholm are more concerned with understanding and discovery than with direct product development. Nevertheless, knowledge gained at Eriksholm feeds strongly into the innovations made in product development teams at the headquarter.

A strong culture of scientific enquiry characterises Eriksholm. Questions are never too complicated to ask. The atmosphere is one of individual learning and challenge, but with a strong team spirit. Research staff disciplines include audiology, psychoacoustics, acoustics, signal processing and anthropology.

In addition to the permanent staff, Eriksholm always has a number of MSc or PhD students.
