Analysis of the Latency of Auditory Brainstem Response Wave V in Infants According to Age, Hearing Threshold and Stimulus Intensity

Background and Objectives The latency of auditory brainstem response (ABR) wave V shifts depending on age, hearing threshold, stimulus intensity. This study was performed to examine the latencies ABR in infants with normal sensorineural loss.Subjects Method retrospective review 318 (539 ears) performed. patients were divided into four groups according age at time test (group A: 0-2 months, group B: 3-5 C: 6-8 D: 9-11 months). using click sound under sedation, intensity adjusted by 10 dB intervals. analyzed intensity.Results Normal detected 320 ears (wave threshold 20 dBnHL or less) loss found 219 ears. Wave decreased increase both hearing-impaired infants. higher thresholds showed longer same normative data varying could be determined.Conclusion present examined will help audiologists evaluate who are referred for test.
