  1. Conductive hearing loss results from outer and middle ear problems that prevent sound reaching the inner ear.

  2. Sensorineural hearing loss caused by damage to sensory cells or nerve fibres in the inner ear.

  3. A combination of conductive and sensorineural hearing loss.

a bridge to the world

The ear is a highly complex organ that transforms sound waves into meaningful information presented to the brain. The brain then makes sense of this information. This is the core of how we develop hearing care. It helps you socialise and communicate with friends, family and colleagues. It connects you with the world around you. In short, the ability to hear is a significant part of a meaningful life.

Break free from limitations

Today, 1 in 10 people over the age of 50 has trouble hearing. The proper treatment for hearing loss is the key to remaining cognitive and socially active. The higher number of people being treated for hearing loss, the less a burden to society from an economic point of view: With treatment, you are able to stay longer on the job market and participate in the many aspects of social life.

Causes and types of hearing loss

Hearing loss can develop at any age and for any number of reasons. The most common cause is age or congenital defects.

However, hearing loss can also develop as a result of infection, after a head injury, if the eardrum is perforated and as a result of taking certain medications, most notably some cancer treatments.

If you recognise signs of hearing loss, you should visit a professional.

An obligation

With more than 10% of the population in OECD countries having trouble hearing, we – and the society in general – have an obligation to offer solutions that can help people and make a difference – on a personal, professional and social level.

the difficult work of hearing

treatment and solutions

Our products are built on the best technology available: Our own. We truly believe in innovation, developing our products from scratch, and in doing so to tailor them for specific audiological purposes. This is the core of our way of doing business, and we make sure that we optimise our processes and know-how so that our skills in innovation and R&D are shared across brands and businesses.

Always innovating

Our more than 12,000 employees are dedicated to innovation and raising the bar in our industry. We refuse to compromise, because we have a responsibility towards millions of people worldwide. Their needs are our daily motivation, and we continuously use feedback and input from current users to create even better solutions. This helps us develop solutions the way they always should be developed – based on facts.

Hearing aids

Since William Demant made a commitment to help people living with hearing loss with the establishment of Oticon a lot has happened in our company. Today, we offer a comprehensive range of solutions that cover all aspects of hearing healthcare. This of course includes hearing aids.

Simply put, a hearing aid is an electroacoustic device that turns up the volume of the world around the user. Hearing aids are usually used to alleviate age-related hearing loss. There are many types of hearing aids, but they all work in a fairly similar way: Sound enters through a microphone. It is then processed, amplified and delivered to a receiver or loudspeaker, which sends the output either directly to the user’s ear canal or via a thin wire to a receiver placed in the ear.

Hearing implants

People with severe to profound perceptive hearing loss, who only have limited benefits – or do not benefit at all – from traditional hearing aids can be helped through our selection of hearing implants.

Bone-anchored hearing systems use the body’s natural ability to transfer sound through bone conduction. The sound processor picks up sound waves just like a conventional hearing aid. But instead of sending waves through the ear canal, the processor transforms them into sound vibrations and sends them through the skull. This way, any problems in the ear canal or middle ear are bypassed.

If the cochlear is too badly damaged, amplifying the sound through a traditional hearing aid will not help. However, a cochlear implant system is an effective solution that can open up the world of hearing. In short, it works by stimulating the auditory nerve in response to sounds captured by a microphone.

Cochlear implants are designed for adults and children with severe to complete hearing loss.

Our products are founded on the best technology available: Our own.

Diagnostic instruments

The first step towards choosing the right hearing solution is getting the right diagnosis. Therefore, we design and manufacture testing equipment across the whole audiological spectrum: Audiometry, tympanometry, electrophysiology, hearing aid testing, balance investigation and rehabilitation are all within our scope.

Our products range from small portable devices to full clinical instruments. Having such a broad portfolio is one of our strengths, because it enables us to provide integrated solutions – whatever the situation.

When you purchase audiological equipment from one of our brands, you are not just guaranteed a quality product, but also extensive support and highly trained personnel with specialised knowledge. We operate in more than 100 countries through a carefully selected network of distributors and service centres to ensure that hearing healthcare professionals receive total support and service.


how cochlear
implants work

A behind-the-ear sound processor captures sound, digitalises it and sends it through an antenna to the implant's receiver, which is located under the skin by the temporal bone. The implant then transforms the digital information into an electric signal that is sent to an array of electrodes inserted in the cochlea. The electrodes stimulate the auditory nerve, which in turn transmits the sound to the brain.

the hearing healthcare market

The hearing healthcare market represents a wholesale value of USD 6 billion per year, with Europe and North America being by far the largest markets.

A growing market

13 million hearing aids are sold every year, and the market grows by 4-6% yearly, largely driven by demographic development.

For cochlear implants and bone anchored hearing systems growth rates are significantly higher than growth rates in hearing aids, 10-12% and 10-15% respectively. And many children need help: It is estimated that out of the 134 million babies born every year, approx. 150,000 are candidates for a cochlear implant.

The market for hearing-diagnostic equipment and accessories is a mature hearing care market with a current approximate growth rate at 0-2%.


Around 1 in 10 people over the age of 50 is living with a hearing loss. The biggest barrier preventing people from getting help is to get them to accept that they need a hearing device – and once they have purchased one, to actually wear it. In average, hearing impaired wait seven years from their hearing loss is recognised until they actually buy a hearing aid.
