Auditory neuropathy spectrum disorder (ANSD) is a form of auditory dysfunction in which peripheral processes can be normal, but neural transmission through the VIIIth nerve and auditory brainstem is disrupted. The perceptual consequences of ANSD are distinct from those of cochlear hearing loss and most commonly include distortion of temporal (timing) cues and altered frequency discrimination. These basic processing deficits can, in turn, affect functional hearing, resulting in severe impairment of speech perception particularly in the presence of background noise. This article will address the mechanisms underlying ANSD, illustrate it's effects in a detailed case study and show evidence for ..
