Hearing & Communication

Hearing and communication is at the heart of our work. Royal Dutch Kentalis is the pre-eminent specialist in the area of diagnostics, care and education for persons who are deaf, hard-of-hearing or deafblind, and to those who have a language impairment. With or without an intellectual disability or autism. 


How can inclusive education work for the deaf learner? What does it take to change from the special education paradigm to the inclusive education paradigm? Which steps help to improve hearing-aid service delivery to hard of hearing persons? We bridge the gap between research and practice, by translating theory in everyday needs and skills.

You're deaf if you have a hearing loss of ninety decibels or more. This means that Deaf children and adults are those that without assistive devices have little to none residual hearing. Some people are born deaf, but your hearing may decline later in life (age deafness). It also happens that people suddenly become deaf in one or both ears.

Hard of hearing people are those who without assistive devices have limited but functional residual hearing. A person who is not able to hear as well as someone with normal hearing – hearing thresholds of 25 dB or better in both ears – is said to have hearing loss. Hearing loss may be mild, moderate, severe or profound.

Deafblindness comes in many shapes and forms. Some people are entirely deaf and blind, some are visually impaired and deaf or hard of hearing and blind. Sometimes deafblindness is congenital, sometimes it occurs later in life.

Seven percent of the population has a Speech Language Impairment (SLI). SLI is a neurological developmental impairment, with a genetical component. People with SLI have difficulties in developing their language, whereas the general development, hearing and intelligence show no problems.

An autism spectrum disorder (ASD) consist of a range of conditions characterized by some degree of impaired social behaviour, communication and language, and a narrow range of interests and activities that are both unique to the individual and carried out repetitively.
