![]() These processes include: auditory discrimination, temporal resolution, temporal sequencing of pitch patterns, binaural integration, binaural separation, auditory figure ground (i.e., auditory closure), neural synchronization and related functions. Following the basic audiological evaluation that establishes hearing sensitivity, an audiologist then determines which specific auditory process to examine. Associated difficulties (e.g., ADHD, dyslexia, language impairment) can lead to additional symptoms including: resistance to remediation for reading deficits and other auditory-based learning, difficulty listening in quiet, difficulty following simple or complex auditory directions, difficulty maintaining auditory attention and frequent requests for repetitions.īehavioral central auditory tests and electrophysiological procedures reveal deficits in specific neurobiological activities underlying auditory processing dysfunction. The classic, direct symptoms of CAPD involve difficulty recognizing speech in the presence of background noise or other competing signals, and difficulty recognizing rapidly presented speech. Current research has been directed at determining the likely, abnormal neural activity that may underlie deviations in auditory perception, as well as methods and strategies for remediation of these conditions.ĬAPD is a condition found in children and adults that typically presents with normal hearing. There are a number of relay points along the pathway that contribute to the complex neural activities of decoding, analysis along frequency, intensity and time domains, distribution, and interpretation of the incoming auditory signal. After sound is decoded in the cochlea or inner ear, it travels via the VIIIth cranial nerve to the brainstem and ultimately to higher areas of the brain. CAPD is an umbrella term that covers a variety of difficulties in processing auditory input due to the interactions of the auditory periphery and the CANS.

There are also online therapy programs that can be beneficial. Adults can benefit from deficit-specific auditory processing therapy and hearing assistive technology ( low-gain hearing aids for auditory processing disorder and/or remote microphone systems). If weaknesses are identified, it is not too late to get help. An APD evaluation uses a battery of tests to assess the integrity of the central auditory nervous system. If an individual passes a basic hearing test but still struggles to understand what they hear, it is imperative to go beyond the basic audiological evaluation to determine the source of this “hidden” hearing problem.
