Acoustic Change Complex (ACC) in Children with Selective Auditory Attention Deficit

Abstract

elective auditory attention (SAA) is defined as the ability to acknowledge some stimuli while ignoring other stimuli that occur at the same time. Difficulty in understanding speech in the presence of background noise is a commonly reported problem. This perceptual difficulty becomes increasingly severe as competing background noise levels increase (i.e., signal‐to‐noise ratio (SNR) decreases). As with speech recognition performance, neural responses as measured by evoked potentials are typically weakened when increasing levels of noise. It is not surprising then, that strong correlations exist between cortical auditory evoked potentials (CAEPs) and speech perception‐in‐noise measures
