Acoustic Change Complex as a Neurophysiological Tool to Assess Auditory Discrimination Skill: A Review.

Area of Science:

• Auditory Neuroscience
• Neurophysiology
• Audiology

Background:

• Acoustic Change Complex (ACC) is an event-related potential.
• ACC reflects auditory discrimination skills.
• Growing research necessitates a review of ACC methodologies and findings.

Purpose of the Study:

• To review the literature on the clinical utility of ACC.
• To assess ACC's role in evaluating auditory discrimination.
• To synthesize findings across diverse populations.

Main Methods:

• Literature search of Medline, Pubmed, Google, and Google Scholar.
• Keywords included "acoustic change complex," "clinical utility of ACC," "ACC in children," "ACC in cochlear implant users," and "ACC in hearing loss."
• 31 relevant research papers were selected and reviewed.

Main Results:

• ACC demonstrates utility as an objective measure in audiology.
• Findings support ACC's application across various populations.
• ACC can supplement subjective audiological tests.

Conclusions:

• ACC is a valuable objective tool for audiology.
• ACC aids in assessing auditory discrimination skills.
• Further research can expand ACC's clinical applications.
