title: The effect of 2000-4000 Hz hearing sensitivity on ABR results.
abstract: Pure-tone hearing sensitivity at 2000, 3000, and 4000 Hz and ABR results were reviewed for 458 patients with cochlear hearing loss. Wave V latency and waveform morphology data from the 916 ears yielded percentages of abnormal ABR results as a function of degree and slope of hearing loss. Threshold sensitivity at all three frequencies influenced ABR latency or waveform. A higher incidence of abnormal ABR results was observed when 3000 Hz thresholds were elevated than when 4000 Hz thresholds were elevated to the same levels. ABR results for various audiometric configurations are reported.
