Auditory Processing Evaluation

Auditory Processing Disorder Overview

Listening is a very complex process. The actions of the outer, middle and inner ear send sounds, via the auditory nerve, to the brain. The brain then interprets the auditory information; for example, it tells us that a particular sound is a dog barking or a bird singing. A child who can hear well but cannot understand the sounds that he or she is hearing may have Auditory Processing Disorder (APD). Some think that APD is for the auditory system what Dyslexia is for the visual system.

Some Symptoms of APD:

  • Difficulty understanding when listening
  • Difficulty following auditory directions
  • Difficulty remembering multi-step instructions
  • Difficulty understanding in noisy or group situations
  • Difficulty taking notes in class
  • Difficulty copying from the board
  • Difficulty reading and spelling
  • Short attention span and fatigues easily
  • Verbal IQ lower than performance IQ

How is APD assessed?

Our team of Audiologists evaluates the child’s auditory processing skills using the following battery of tests:
  • A comprehensive hearing evaluation including tympanometric testing and acoustic reflexes evaluation
  • Otoacoustic emission evaluation
  • Screening questionnaire

Our offices the Buffalo model for diagnosing Auditory Processing, the tests include

  1. Speech in noise testing:   Single-syllable recorded word recognition lists are used to evaluate understanding in noise. Each ear is tested separately.
  2. Staggered spondaic word testing:  Binaural test with different words going to each ear. Some of the words are non-competing (arriving at the two ears at different times) and others are competing (arriving at the two ears at the same time). The patient is to repeat all the words heard.
  3. Phonemic synthesis testing:  The patient hears words presented sound-by-sound to both ears. The task is to identify the word that was given (a type of sound-blending task).

Next Step

An audiologist can determine the exact nature of your child’s issues through a routine hearing test, which will rule out any physical hearing problems by testing their ability to hear a range of frequencies. If no hearing loss is present, behavioral and electrophysiological testing is administered.
