Central Auditory Processing

When the brain hears… but doesn’t quite understand.

Auditory processing is the brain’s ability to understand the sounds that the ears perceive. The ears capture sounds and transform them into electrical signals, which are transmitted to the brain for analysis and comprehension.

The Role of Central Auditory Processing

Therefore, central auditory processing is everything that happens between the two ears.

These abilities develop from early childhood and continue to refine until adolescence. When one or more of these functions are impaired, it is referred to as an Auditory Processing Disorder (CAPD).

It is sometimes difficult to distinguish between language disorders, concentration disorders, behavioral disorders… It is important to involve several healthcare professionals for a comprehensive evaluation.

Depending on the auditory profile, different interventions may be considered. Each plan is entirely personalized to the individual being evaluated.

Central Auditory Processing Disorder (CAPD)

APD can lead to several difficulties:

  • Comprehension in noise
  • Comprehension of rapid speech
  • Difficulty following long or complex instructions
  • Frequently asking for repetition
  • Answering a question incoherently
  • Learning difficulties
  • Fatigue, anxiety

Functions of Central Auditory Processing

Auditory Discrimination

Differentiating two sounds. This allows for distinguishing voices, noises, and sound nuances that make up a conversation or an environment.

Binaural Integration

Ability to combine information from the right and left ears.

Sequential Organization

Ability to place sounds in the correct order. Essential for following a conversation or grasping the structure of a message.

Sound Localization

Identifying where a sound originates. This helps to orient oneself and understand the sound interactions around them.

FAQ

At what age can APD be diagnosed?

Generally from 7 years of age, the age at which the central auditory system is sufficiently mature to allow for reliable tests.

Is APD a form of deafness?

No. Peripheral hearing (the ears) functions well, but the brain misinterprets the information. One hears, but does not always understand.

Does APD disappear over time?

It does not disappear completely, but with appropriate intervention, it is possible to improve auditory comprehension and develop effective compensatory strategies.

Can APD affect adults?

Yes. It can be present since childhood without having been diagnosed, or appear later after trauma, a stroke, or aging of the auditory system.
