PURPOSE: to determine the ABR thresholds and the latency of V wave in hearing infants at the frequencies: 0.5, 1, 2 and 4 kHz. METHODS: 23 infants with no risk factors concerning hearing loss that had transient otoacoustic emissions (TOAE) and automatic auditory brainstem response (A-ABR), bilaterally present, were evaluated. RESULTS: ABR thresholds were obtained in average, namely: 34.2 dBHL, 25.4 dBHL, 19 dBHL and 17.5 dBHL for frequencies of 0.5, 1, 2 and 4 kHz, respectively. The mean latency of V wave at 70 and 20 dBHL, respectively, at a 0.5 kHz frequency were 10.75 ms and 15.2 ms, 1 kHz 8.9 ms and 13.4 ms; 7.7 ms and 10.2 ms at 2 kHz, and as for4 kHz they were 7.3 ms and 9.4 ms. CONCLUSIONS: the found values can be used in clinical practice in order to guide the differential diagnosis of hearing loss, complementing the evaluation as for hearing infants.
