An auditory processing disorder test is a series of listening tests given by an audiologist to check how well your brain makes sense of sounds and speech. People with auditory processing disorder (APD) usually pass a standard hearing test, yet their brain struggles to process what they hear, especially in noise. If you or your child often ask “what?” or lose track of speech when there is background noise, a formal audiology evaluation is the only way to find out whether APD is the cause.
Who Can Test for Auditory Processing Disorder?
An auditory processing disorder evaluation cannot be conducted by a general practitioner, pediatrician, or therapist alone. In the United States, an APD diagnosis can officially only be made by a licensed audiologist holding a doctoral degree in audiology (AuD or PhD), state licensure, and often clinical certification such as the Certificate of Clinical Competence in Audiology (CCC-A) from the American Speech-Language-Hearing Association (ASHA). ASHA guidelines established in 2005 emphasize that audiologists are the professionals qualified to diagnose APD, a position confirmed by medical centers including the Cleveland Clinic.
Diagnosing APD in children often involves a multidisciplinary team, though the audiologist remains the sole diagnostic lead:
- Licensed Audiologist: Leads the evaluation, administers the diagnostic battery, and interprets auditory processing performance.
- Speech-Language Pathologists (SLPs): Collaborate with the audiologist to delineate speech-language and cognitive factors, though they cannot diagnose APD independently.
- School Teachers: Contribute observational data regarding classroom learning and attention.
- Psychologists: Administer cognitive tests to evaluate general cognitive function.
Dedicated APD testing is specialized, and not every audiology clinic offers it. One practice in Northeast Indiana, for example, reports being the only dedicated APD provider within a 250-mile radius. To find an auditory processing disorder test near you, ask your pediatrician, family doctor, or an ENT for a referral, and call clinics ahead to confirm they run a full central auditory processing evaluation, not just a hearing test.
Minimum Age Requirements: Auditory Processing Disorder Test for Children vs. Adults
Age matters when you schedule an auditory processing evaluation, because brain function, language, and attention are still developing in young children. Clinical guidelines set these age limits:
- Children Under 7 Years: According to clinical guidelines from the NHS, the University Hospital Southampton, and the Weill Cornell Medical Center, comprehensive diagnostic APD test batteries are generally not administered to children under 7 years of age. While select private clinics assess speech-in-noise comprehension starting at 3.5 years (3;6 years), a reliable and definitive diagnostic battery requires reaching 7 years of age.
- Ages 5 to 6: Standardized diagnostic tools like the SCAN-3 Children battery include normative data starting at age 5, and the non-verbal Random Gap Detection Test (RGDT) can be administered at age 5. However, audiologists interpret results in 5-year-olds with caution.
- Children (Ages 7 to 12): Full diagnostic test batteries achieve clinical reliability from age 7 onward, as children reach the cognitive and auditory maturity necessary to complete standardized testing.
- Adolescents and Adults: Standardized batteries such as the SCAN-3 Adult & Adolescent protocol evaluate individuals from age 13 through 60 years.
Screening vs. Formal Diagnosis: How to Tell if You Have APD
Screening questionnaires help you, your child’s teacher, or you as an adult spot listening problems and decide whether a clinical evaluation makes sense. Recognized screening tools include:
- Fisher’s Auditory Problems Checklist: A 25-item screening questionnaire developed in 1976, completed by parents or teachers to identify listening difficulties.
- Auditory Processing Domain Questionnaire (APDQ): A free online screening tool designed for children and adolescents aged 7 to 17 that evaluates auditory processing, attention, and language performance.
- Evaluation of Children’s Listening and Processing Skills (ECLiPS): A psychometrically validated parent questionnaire that quantitatively measures Listening Difficulties (LiD).
- Screening Checklist for Auditory Processing in Adults (SCAP-A): A 12-item adult screening questionnaire assessing auditory memory, auditory attention, auditory closure/separation, and temporal ordering.
- Psychology.com Online Self-Test: An online questionnaire evaluating four categories: speech in noise, word discrimination, auditory memory and instructions, and attention and fatigue.
A typical screening question asks how often an individual says “What?” or “Huh?”, even in quiet listening environments; frequent requests for repetition are a strong indicator. However, questionnaires and online self-tests cannot establish an official medical diagnosis; clinical audiological testing is mandatory to confirm APD.
How Do You Test for Auditory Processing Disorder? The Diagnostic Steps
A full clinical evaluation for auditory processing disorder takes place in an audiology clinic, and the APD test battery alone takes 1.5 to 3 hours. Here is what to expect:
- Comprehensive Audiological Evaluation (CAE): The audiologist begins with baseline testing to rule out peripheral hearing loss and middle ear dysfunction before APD testing begins.
- APD Diagnostic Test Battery Administration: The patient undergoes a 1.5- to 3-hour battery of multiple short tests designed to evaluate specific auditory strengths and weaknesses.
- Sound Presentation Under Headphones: Wearing specialized headphones, the patient listens to calibrated speech and non-speech stimuli presented under varying listening conditions, such as background noise or competing words delivered to each ear simultaneously (dichotic listening).
- Normative Scoring and Profiling: The audiologist analyzes the results against age-matched norms, calculating scaled scores, percentile ranks, and ear advantage scores to generate an individual auditory profile.
In addition to behavioral test batteries, medical centers such as the Mayo Clinic may use objective tests including tympanometry, acoustic reflex testing, Auditory Brainstem Response (ABR), and evoked potential tests to assess the auditory pathway from the inner ear to the brainstem. Clinically, APD is typically diagnosed when a patient demonstrates abnormal scores (below normative thresholds) on two or more subtests across the battery.
Core Categories in an Auditory Processing Disorder Test Battery
A complete auditory processing evaluation checks four areas of listening:
| Test Category | What It Measures | Standard Diagnostic Subtests & Minimum Ages |
|---|---|---|
| Dichotic Listening | Binaural integration and binaural separation (processing different signals presented to each ear simultaneously) | Pediatric Speech Intelligibility (ages 3+), Competing Sentences (ages 5+), Dichotic Digits (ages 7+), Synthetic Sentence Identification (ages 11+) |
| Temporal Processing | Temporal resolution, pattern recognition, and sound sequencing | Random Gap Detection Test (RGDT, nonverbal, ages 5+), Gaps-In-Noise (GIN, ages 7+), Pitch Pattern Sequence / Frequency Pattern Test (ages 8+), Duration Pattern Sequence (ages 11+) |
| Monaural Low Redundancy | Auditory closure (interpreting degraded, filtered, or time-altered speech) | Time Compressed Sentence Test (ages 6+), Low Pass Filtered Tests (ages 11+), Synthetic Sentence Identification – Ipsilateral Competing Message (ages 11+) |
| Binaural Interaction | Combining auditory information across both ears | Masking Level Difference (MLD), Spondee Binaural Fusion, Rapid Alternating Speech (all suitable for children and adults) |
Standardized diagnostic tools like the SCAN-3 incorporate core subtests—Filtered Words, Auditory Figure-Ground, Competing Words, and Competing Sentences. It can be used as a 10-to-15-minute screening or as a full 30-to-45-minute diagnostic battery. Dedicated subtests offer specific diagnostic insights: the Frequency Pattern Test (Pitch Pattern Sequence) is a non-verbal test for ages 8 and older that assesses temporal processing and identifies lesions of the left temporal cortex, while the Gaps-In-Noise (GIN) test measures temporal resolution sensitive to central auditory nervous system dysfunction. Auditec bundles several of these standardized measures (including GIN, RGDT, Pitch Pattern, Duration Pattern, and MLD) into a diagnostic test package (CD170-9) for audiologists.
Common Myths vs. Facts About Auditory Processing Disorder
These are the most common misconceptions about APD:
- Myth 1: APD is a form of peripheral hearing loss. Fact: Individuals with APD typically show normal pure-tone hearing sensitivity. However, when listening to speech in noise, children with APD can perform up to 40% worse than their peers, highlighting a central processing deficit rather than a hearing threshold loss.
- Myth 2: Any child struggling with listening in school has APD. Fact: True APD is relatively rare. Estimates range from about 2% to 5%, depending on the source and the population studied (Great Ormond Street Hospital, Weill Cornell, Nationwide Children’s Hospital). One Houston audiology practice estimates that about 15% of school-age children show some level of auditory processing difficulty, but not all of them meet the formal criteria for APD.
- Myth 3: Speaking louder resolves the issue. Fact: Increasing volume does not resolve APD because the dysfunction occurs at the neural processing level. Repeating or rephrasing statements into clearer sentences is an effective accommodation.
- Myth 4: An online questionnaire provides a formal medical diagnosis. Fact: Questionnaires and online self-assessments cannot diagnose APD. Audiological testing conducted by a licensed audiologist is required.
Practical Next Steps, Accommodations, and Therapy
After a confirmed diagnosis, your audiologist puts together a personal plan that combines classroom changes, assistive listening technology, and auditory training.
Classroom and Environmental Accommodations
In the United States, students with APD can qualify for school support and accommodations under the Individuals with Disabilities Education Act (IDEA), often as a specific learning disability. Common adjustments include:
- Strategic Classroom Seating: Seating the student at the front of the classroom with their back to the window reduces auditory distractions and makes speech easier to follow in a noisy room.
- FM Systems (Frequency-Modulated Systems): The teacher wears a microphone that transmits speech directly to a wireless receiver or earpiece worn by the child, bypassing ambient classroom noise.
- Acoustic Modifications: Installing carpets and upholstered furniture helps absorb sound and reduce room reverberation.
Computer-Based Auditory Training Software
Auditory training can be done one-on-one with an audiologist or online at home to help with understanding speech in noise. Commonly used programs include:
- Fast ForWord: A computer-based brain training program with adaptive exercises for auditory discrimination, auditory memory for sequences, and following instructions. Providers cite neuroimaging studies in support of its use for central auditory processing disorder (CAPD).
- Sound Storm: A game app for children aged 6 to 12 with spatial processing disorder; its developer describes it as clinically validated.
- Earobics: Alongside Fast ForWord, Earobics represents one of the two most frequently cited computer-based auditory training (CBAT) programs in APD research.
Other apps exist, but check that they are still maintained before you rely on them. The Auditory Training app for iOS and Apple Watch, for example, was built for people with APD but has since dropped its audio support.
Daily Communication Tips for People with APD
Small changes in how you talk make daily listening easier:
- Maintain Face-to-Face Contact: Speak directly face-to-face so lip reading and visual facial cues support auditory processing.
- Break Down Complex Instructions: Deliver verbal instructions in short, individual steps, presenting no more than two steps at a time.
- Pair Speech with Visual Aids: Supplement verbal instructions with visual aids, such as written notes, lists, or diagrams, as individuals with APD are often visual learners.
- Reduce Background Noise: Turn off competing sound sources like televisions or radios during conversations, and use rooms with carpets and upholstered furniture to reduce echo.
- Rephrase Unclear Information: If a message is not understood, repeat or rephrase the sentence rather than speaking louder.
Frequently Asked Questions
How can I tell if I have an auditory processing disorder?
Common indicators include difficulty understanding speech in noisy settings, frequently asking “What?” or “Huh?” even in quiet rooms, and struggling with complex verbal instructions despite normal pure-tone hearing. A licensed audiologist must perform formal testing to determine whether APD is present.
Who can test for auditory processing disorder?
Only a licensed audiologist holding an AuD or PhD, along with state licensing and clinical credentials such as the CCC-A, is qualified to diagnose APD. Speech-language pathologists, psychologists, and educators assist with multidisciplinary observations, but they cannot diagnose APD independently.
What is a listening disability?
The term listening difficulties (LiD), often called a listening disability, describes functional trouble understanding speech in everyday environments without meeting full diagnostic criteria for APD. Validated parent questionnaires like ECLiPS help quantify LiD and differentiate functional listening challenges from central neurological auditory processing deficits.
What software is available for people with auditory processing disorder?
Commonly used computer-based auditory training programs include Fast ForWord, which trains auditory discrimination and memory sequences through adaptive exercises, and Sound Storm, a game app for children aged 6 to 12 with spatial processing disorder. Earobics is also widely cited in APD auditory training research.
What are some practical tips for people with auditory processing disorder?
Key strategies include speaking face-to-face, limiting instructions to no more than two steps at a time, using visual notes and aids, cutting background noise from televisions or radios, and rephrasing statements rather than raising vocal volume.
