  • Title: Auditory brainstem responses in a case of high-frequency conductive hearing loss.
    Author: Gorga MP, Reiland JK, Beauchaine KA.
    Journal: J Speech Hear Disord; 1985 Nov; 50(4):346-50. PubMed ID: 4057976.
    Abstract:
    Click-evoked auditory brainstem responses were measured in a patient with high-frequency conductive hearing loss. As is typical in cases of conductive hearing loss, Wave I latency was prolonged beyond normal limits. Interpeak latency differences were just below the lower limits of the normal range. The Wave V latency-intensity function, however, was abnormally steep. This pattern is explained by the hypothesis that the slope of the latency-intensity function is determined principally by the configuration of the hearing loss. In cases of high-frequency hearing loss (regardless of the etiology), the response may be dominated by more apical regions of the cochlea at lower intensities and thus have a longer latency.
