Auditory Processing Disorder

What Is Auditory Processing Disorder?

Auditory Processing Disorder (APD) affects how the brain processes what the ears hear — not hearing itself. Students with APD may have trouble distinguishing similar sounds, following multi-step verbal directions, or filtering out background noise, even though their hearing tests normally.

A Related Concept: Language Processing Disorder

Language Processing Disorder (LPD) is a specific type of Auditory Processing Disorder. While APD affects how the brain interprets all incoming sound — including background noise, sound sequencing, and sound location — LPD relates specifically to processing language, and can affect either expressive language (what a student says) or receptive language (how well they understand what others say). The supports below address both APD and LPD, since both involve the same underlying language-processing skills.

How Porter Academy Addresses Auditory Processing and Language Processing Disorders

• Language & Literacy, incorporating the Lindamood-Bell program, directly targets the sensory-cognitive and language-processing skills that underlie auditory processing (see our Reading & Language Arts page for more)
• Multi-sensory instruction throughout the day means students aren’t relying on auditory input alone — information is layered with visual and hands-on components
• Small group instruction reduces competing background noise and makes it easier for students to follow along
• Visual supports and written handouts reduce reliance on verbal instructions alone
• Occupational Therapy works on sensory processing broadly, which supports the same underlying skills involved in auditory processing
