The JIAS (Sound Therapy) Programme

Johansen Individualised Auditory Stimulation

Johansen Individualised Auditory Stimulation (also known as Johansen Sound Therapy) was developed in Denmark by Dr. Kjeld Johansen, director of the Baltic Dyslexic Research Laboratory, from the original work by Christian A. Volf.

How does it work?

JIAS has been developed to stimulate the nerve pathways into and within the brain. It is directed particularly to the pathways between the right ear and the left hemisphere of the brain, where information from the ears is first received and from there on down to the deeper processing areas.


Various forms of brain scanning have shown that this stimulation produces increased numbers of connectors in the form of dendrites and synapses. Connections within the language centres therefore speed up and are made considerably more efficient with the result that the processing of language is more efficient.

Inner Ear

Concentration and understanding improves as information is dealt with more quickly and does not swamp the child in the way they did before. More information is able to be dealt with at a time. Literacy skills (reading and spelling) are often seen to improve as the child becomes more proficient at analysing the sound structure of words.

JIAS Sound Therapy can be of benefit to children, adolescents and adults with a variety of speech and/or language difficulties, both spoken and written (including specific learning difficulties and dyslexia). Children for whom reading and spelling are problematic often find it easier to analyse the sound structure of words, following the Johansen Sound Therapy programme. Together with good targeted teaching, this can help their literacy skills significantly. For older individuals, the programme may take longer to complete than for younger people.

Difficulties which may benefit from JIAS

Johansen IAS can be of benefit to children, adolescents and adults with a variety of speech and/or language difficulties, both spoken and written. These might include difficulties with one or several of the following:

  • Speech Sounds (pronouncing speech sounds correctly)

  • Receptive Language (understanding of language)

  • Expressive Language (speaking)

  • Auditory Processing/ listening

  • Written Language (dyslexia)

  • Reading

  • Spelling

  • Phonological awareness (awareness of speech sounds)

  • Dyspraxia

  • Autism Spectrum Disorders

  • Understanding and remembering information and instructions

  • Concentration

  • Self confidence and self esteem

  • Behaviour – when it may be due to poor communication skills

  • Hypersensitivity to loud or particular sounds / noises

The JIAS Individual Programme

Full Diagnostic Assessment


Areas Assessed:

  • Audiogram assessment, where the left and right ears are tested and ear dominance is determined. The audiogram indicates the listening ability and auditory perception at a variety of frequencies and decibel levels in relation to the Optimum Listening Curve. It also helps to identify areas of weakness in language perception as well as hyper and hyposensitivity to sounds.

  • Laterality Test

  • Dichotic Listening Test

The assessment takes approximately 1 hour.

Following the assessment, a verbal report of findings will be discussed and recommendations made. A written report will be sent out 2 weeks after your initial assessment.


The treatment involves listening to a series of specially recorded music CD's for 10 minutes a day, 6 days a week, for a specified time frame. The average programme lasts 9 months.

The CD's/downloaded music can be listened to at any time of the day, through headphones (with a definite left and right ear) on a personal stereo/device. Music specific to individuals and may not be listened to by anyone else.



After the specified listening period, a review is required to determine the changes that have taken place in the listening profile. An audiogram is required at each review. New music is then made, taking into account the changes indicated by the new Audiogram results.

Reviews take approximately 30 minutes.
