APD stands for Auditory Processing Disorder

Auditory processing is a term used to describe what happens when the brain recognizes and interprets the sounds around you, so someone who may have ADP has difficulty interpreting information heard.


Researchers are learning more about how the brain works, and have yet to find out what causes ADP.


Persons with APD often:

  • Have trouble paying attention to and remembering information
  • Appear to have poor listening skills or behavior problems
  • Need more time to process information
  • Develop a dislike for locations with lots of background noise

Testing for APD

All APD evaluations at CMU include a hearing evaluation. Due to the variablitiy in children's development at ages and the lack of adequate testing tools for young children, APD evaluations will not be scheduled for children until they are seven (7) years old.

Auditory Processing Disorders are often confused with, or complicated by, the existence of other issues related to language and learning. Therefore, it is our policy that prior to an APD evaluation at CMU's Carls Center that we review other contributing factors to rule out hearing loss, language disorders, learning disabilities and cognitive/behavioral disabilities.

Ruling out these difficulties will better enable us to identify a weakness in auditory processing skills. As a result, we require a language evaluation prior to the APD appointment and have it faxed to our office at 989-774-1891 at least one (1) week prior to the scheduled appointment.

In order to help us conduct your child's testing efficiently and give you appropriate recommendations, we ask that you bring the following information to the appointment if possible:

  • The results of your child's most recent hearing test, if he/she has had one.
  • A copy of your child's Individualized Education Plan (IEP) if the child is receiving any special eduactional services.
  • A copy of the speech and language evaluation and/or therapy goals for this year if your child is receiving speech-language servcices.

How Long Will the Testing Take?

All auditory processing evaluations performed at Central Michigan University include a complete hearing evaluation. Due to the complex nature of APD testing, the appointment is expected to take several hours. Breaks will be provided as needed, and the testing may need to be completed over two dates.

Please do not hesitate to call our office 989-774-3904 and ask to speak with one of the Audiologists if you have any questions. If you are unable to keep your appointment, please call the office to reschedule. Failure to not notify the clinic prior to your appointment time may result in problems or delays with rescheduling for this very important evaluation.
