Baseline Hearing Evaluation
We begin with a thorough hearing test to rule out hearing loss and establish a clear picture of your auditory system before auditory processing testing begins.

Auditory Processing Disorder (APD) occurs when the brain has difficulty interpreting what the ears hear, and it is one of the most commonly missed diagnoses in both children and adults. Someone with APD may pass a standard hearing test yet still struggle to follow conversations, understand speech in noisy environments, or retain spoken information. At Sound Hearing Audiology and Speech, auditory processing testing is conducted by Dr. Robin Zeller, whose dual certification in Audiology and Speech-Language Pathology gives her a uniquely comprehensive perspective on how hearing, processing, and communication intersect.
We begin with a thorough hearing test to rule out hearing loss and establish a clear picture of your auditory system before auditory processing testing begins.
Dr. Zeller administers a battery of tests that assess how the brain handles sound, including processing in noise, auditory memory, and sound discrimination.
We review findings in detail and provide personalized recommendations including therapy, assistive technology, school accommodations, or further referrals as needed.
APD is frequently misidentified as attention difficulties, learning disabilities, or behavioral issues, leaving individuals without the right support for years, sometimes decades.
Auditory processing testing by a qualified audiologist ensures an accurate diagnosis and a clear path forward, replacing years of frustration with targeted, effective support.


At Sound Hearing Audiology and Speech, Auditory processing testing is performed exclusively by Dr. Robin Zeller, a dually certified audiologist and speech-language pathologist with decades of diagnostic experience across school, clinical, and research settings. Her rare combination of credentials means she evaluates not just how the auditory system functions, but how processing difficulties connect to speech, language, and learning in a way that few practitioners are equipped to do. If you suspect APD in yourself or your child, call us today at (516) 932-7577. Dr. Zeller is here to provide the thorough, expert evaluation you deserve.
Children with APD may struggle to follow multi-step directions, have difficulty hearing in noisy classrooms, or seem inattentive despite normal hearing test results. If your child has been flagged for attention or learning difficulties but hearing tests came back normal, APD is worth investigating.
Yes. APD in adults is more common than many people realize, and often goes unrecognized for years. Adults may notice difficulty following conversations in noise, trouble retaining verbal information, or fatigue from listening, all of which warrant a professional evaluation.
Formal auditory processing testing is typically conducted from age 7 onward, when the auditory system is developed enough to produce reliable results. Dr. Zeller can advise on appropriate screening and monitoring options for younger children who may be showing early signs.
Hearing loss affects how well sound is detected by the ears, while APD affects how the brain interprets and processes that sound. It is possible to have both conditions simultaneously, which is why a comprehensive evaluation that assesses both is so important.
A complete auditory processing evaluation typically takes two to three hours, allowing time for baseline hearing testing, the full processing battery, and a thorough results discussion. Dr. Zeller ensures you leave with a clear understanding of the findings and what they mean going forward.
Coverage varies by insurance plan, and our staff can help you verify your benefits ahead of your appointment. We work to make testing as accessible as possible so that cost is never a barrier to getting the answers you need.
