How does it work?

Johansen IAS is a home based Sound Therapy programme which involves listening to specially recorded music for ten minutes a day. The music is specifically designed to gently change and organise auditory processing by stimulating the nerve pathways into and within the brain in particular the areas dealing with language. It addresses underlying auditory processing which helps noticing discrimination and organisation of the detail of sound.

Learning to Listen Well

Even with normal hearing, a child's ability to listen well and process what they hear maybe disorganised for different reasons, including:

  • Inconsistent early hearing because of ear infections or Glue Ear
  • Poor attention
  • Delayed language development
  • Inherited differences in how they learn, such as dyslexia

When listening is difficult, inefficient or inconsistent it may affect the development of:

  • Attention and concentration
  • Understanding spoken language
  • Clear speech
  • Social communication
  • Noticing letter sounds for reading and spelling
  • Confidence and self esteem

The Programme

  • The initial assessment includes gathering background information, the use of checklists, standardised tests and audiometry as appropriate for the age and abilities of the individual.
  • An individually customised programme of CDs is listened to for 10 minutes a day over 9-12 months at home. The CDs are customised according to information obtained from individual assessment, including audiometry where appropriate.
  • A review will take place every 6-8 wks, depending on age of client. This enables assessment on progress and planning of next steps of programme.


  • Listen for 10mins every day
  • Listening at a regular time is very helpful in establishing a good routine
  • Listen in a quiet room
  • Do not eat, drink, talk, watch TV/Video, read or write while listening
  • Try to relax while listening
  • Many children like to listen in bed
  • If attention is a problem colouring, playing peacefully with Lego, simple puzzles or plasticine may help

Equipment Required


  • Good headphones are very important
  • Cheaper headphones may alter the balance of the music as they often have built-in 'bass boost'
  • More expensive headphones are more likely to be designed for the classical music market with a balanced input across all frequencies.
  • It is crucial to wear the headphones on the correct ears!!


  • The CD player should have a frequency response range at least 40Hz to 16000Hz
  • If there is a built in Equaliser, Bass Boost or Left/right balance control... Switch off.
  • The music the child listens to should be as it is on the CD, not altered or filtered in any way
  • The music should not be downloaded to an i-Pod or equivalent as this compromises quality

Neural Plasticity

Stimulation can encourage maturation and change because of 'Neural Plasticity'. This is an umbrella term for changes to the organisation of pathways in the brain, including those for hearing and language, and the resulting behaviour.

Some maturation and change happens over time and may be independent of experience.

Some changes are dependent upon activity or experience. Some changes happen more readily during 'sensitive periods' in development.

Although it is accepted that 'the younger the brain the greater the plasticity', more recent evidence indicates that age is only one factor in neuro plasticity and change can be observed even into old age, if stimulation is sufficient-

  • Frequency (often enough)
  • Duration (for long enough)
  • Intensity (strong enough)
  • AND - There is sufficient motivation (co-operation)
