Abstract:
Background
Tinnitus is an auditory sensation frequently following hearing loss. After cochlear injury, deafferented neurons become sensitive
to neighbouring intact edge-frequencies, guiding an enhanced central representation of these frequencies. As psychoacoustical
data 1–3] indicate enhanced frequency discrimination ability for edge-frequencies that may be related to a reorganization within the
auditory cortex, the aim of the present study was twofold: 1) to search for abnormal auditory mismatch responses in tinnitus
sufferers and 2) relate these to subjective indicators of tinnitus.
