Auditory Processing Disorders

What is an Auditory Processing Disorder (APD)?

Jack Katz, one of the most respected researchers in the field simply defines auditory processing as “what we do with what we hear”!

Children and adults with APD have normal hearing and intelligence but problems listening, storing, retrieving and organising what they hear.

What causes APD?

We can divide children and adults into 4 groups based on suspected cause.

1. Patients with evidence or suggestion of neurological damage.  For example anoxia, birth trauma, head injury etc.

2. Patients who have a reasonably strong history of APD, speech and language difficulties, or learning difficulties.

3. Patients who have a history of ear infections especially with fluctuating hearing.

4. Patients with unknown cause.  This group can include children with developmental delays in their auditory system or unexplained developmental difficulties.

What can be done for APD?

There are 3 possible approaches to the management and treatment of APD.  The Audiologist or Speech Pathologist may recommend a combination of some or all of these approaches.

• Environmental modification:

  • Improving the listening environment

  • Preferential seating in class

  • Repeating and rephrasing

  • Using visual aids

• Enhancing the signal using:

  • Personal FM systems

  • Classroom amplification

• Direct therapy focusing on the areas of difficulty identified in the assessment

What other professionals may need to be consulted?

• Paediatrician or GP  for general health check 

• Optometrist for vision assessment and also visual processing and eye movement 

• Psychologist for intelligence testing to help identify any strengths or weaknesses and to give insight into the person’s learning styles

• Speech Pathologist for full language and speech evaluation including narrative and phonological awareness assessment
