Auditory Processing

A young child's hands are pictured pointing to a white card with a black capital letter B on it. Next to the card is another with the letter A on it.

Auditory Processing Disorder (APD) is a hearing condition that disrupts the way the brain processes sound and can only be diagnosed by an Audiologist. People with auditory processing issues have difficulty understanding speech even though they do not have peripheral hearing loss. While this disorder can affect individuals of all age groups, it is most commonly observed in children, with an estimated prevalence of 2-7% among school-aged children. APD can cause difficulty with learning how to read and write.

APD encompasses various distinct types, each characterized by its own unique set of symptoms. These symptoms can have a significant impact on an individual's life, making it challenging to excel in academic settings, work environments, and social interactions.

Despite ongoing research, the precise cause of APD remains unclear. However, it is believed to result from a combination of genetic and environmental factors. Potential contributing factors include brain injuries, premature birth, exposure to lead poisoning, recurrent middle ear infections (otitis media), underlying learning disabilities, and conditions like attention deficit hyperactivity disorder (ADHD).

What to Expect

An auditory processing evaluation is a comprehensive assessment that determines how well a person’s brain processes sound. Specific tests used to assess auditory processing disorders vary depending on the person’s age. Prior to your visit, we will provide a phone interview to see if we feel an auditory processing evaluation may be beneficial.

Here's what you can expect during your visit:

  • Case History 
    Our audiologists will interview you or the guardian about hearing history, medical history, developmental milestones, and any concerns you have about your hearing or your child’s hearing. This will also include questionnaires for the parent/caregiver and/or patient.

  • Hearing Test
    Before evaluating auditory processing skills, a standard hearing test will be performed to rule out any hearing loss or issues with the peripheral auditory system or to determine if you have normal hearing sensitivity.

  • Speech Testing
    Various tests will be performed in quiet and in noise. These tests will show where the patient is having difficulty processing sound.

  • Results and Consultation
    Following the evaluation, the audiologist will go over the general findings, followed by a comprehensive report detailing the areas of auditory processing concern. This report will be provided within a week following the evaluation. Auditory training and follow up may be recommended.

    Results Discussion
    After the tests are completed, the audiologist will discuss the results with you. They will review the audiogram (unless previously performed) and all other peripheral hearing tests. The specific APD tests will be reviewed and explained. Within one week of the evaluation, a full, written, comprehensive report will be given that will outline the specific areas where difficulty may be noted.

    Treatment Options
    Depending on your results, the audiologist may discuss treatment options, which could include auditory training, hearing aids, assistive listening devices, medical referrals, or strategies for communication improvement.

    Follow-Up
    If auditory training is recommended, a 12-week outline will be provided to further discuss the training sessions.

  • There is no cure for APD, but there are a number of treatments that can help people manage their symptoms. Treatment options may include: auditory training, speech therapy, hearing aids, environmental modifications, compensatory strategies, classroom & educational support, and family & individual support.
