Testing Process

The testing process:

The Central Auditory Processing evaluation is broken down into two parts and requires two separate appointments.

The first appointment is called “Pre-APD” and consists of the following evaluations:

  1. Case history
  2. Audiogram
  3. Tympanogram, acoustic reflexes and acoustic reflex decay
  4. Otoacoustic emissions
  5. Auditory Brainstem testing

The second part of the evaluation is called the APD appointment, and is done entirely in the sound booth using standardized testing materials.

It is important to note that each testing session spans from one to two hours depending on the amount of supplemental tests that may be used. Additional testing may be required based on the individual performance of the child. Once APD testing has been completed, the audiologist will present the findings and make appropriate recommendations for the next step.
