Loss of synchrony capture of vowel formants with noise-induced hearing loss. Representative neural responses in cats to the vowel /ε/ (top) from a control auditory-nerve fiber (middle plots) and noise-exposed fiber (lower plots). The characteristic frequencies (CFs) of the fibers were near F₃. While the control fiber shows strong synchrony capture of TFS information near F₃ (i.e., near CF), the noise-exposed fiber shows synchrony to a broader range of lower frequency TFS information.
