“…For the frequency of 500 Hz, the mean latency found at 80 dBnHL was of 8.53±0.17 ms, and at 30 dBnHL, of 13.73±0.57 ms. Only one study assessed latency at 80 dBnHL 34 , and the mean latency of wave V found was longer than in the present study (Full-term children: 11.0±0.7 ms; preterm children: 12.1±0.3 ms). At the intensity of 30 dBnHL, some studies have found mean latencies similar to those in the present study 18,20,35 . In the frequency of 1000 Hz, at 80 dBnHL, the latency time was 8.61±0.38 ms, shorter than the results of another study conducted in Brazil frequency suggest responses at intensities lower than 20 dBnHL 10,14,[19][20][21][22] .…”

Objetivo determinar os níveis mínimos de resposta (NMR) e a latência da onda V do Potencial Evocado Auditivo de Tronco encefálico por Frequência específica (PEATE-FE) em neonatos ouvintes normais nas frequências de 0.5, 1, 2 e 4 kHz por via aérea e via óssea e determinar valores normativos. Métodos foram avaliados neonatos com audição normal, sendo realizado o PEATE-FE nas frequências de 0.5, 1, 2 e 4 kHz, tanto por via aérea (VA) quanto por via óssea (VO). Para cada frequência, foram avaliadas 12 orelhas em um total de 18 neonatos. A análise dos resultados avaliou o tempo de latência e a presença da onda V até a intensidade de 20 dBnNA para quatro intensidades e para os dois tipos de condução (aérea e óssea). Resultados observou-se aumento da latência da onda V com a diminuição da intensidade e maiores latências nas frequências mais baixas, tanto na VA quanto na VO. Porém, em fortes intensidades, em ambas condições, não houve diferença entre as latências de 0.5 e 1 kHz, contrariando os achados da literatura. Para VA, na frequência de 500 Hz, houve presença da onda V até 30 dBnNA em todas as orelhas, e em 1000 Hz, 11 orelhas (91,66 %) apresentaram resposta em 20 dBnNA; nas demais frequências, 100% das orelhas avaliadas apresentaram resposta em 20 dBnNA. Na VO, a presença da onda V em 20 dBnNA foi observada em todas as frequências estudadas. Conclusão os valores descritos podem ser considerados normativos e utilizados na clinica como padrão de normalidade, auxiliando no diagnóstico diferencial da perda auditiva ao nascimento.

“…In infants beyond the neonatal period, Kulekci et al (2007) provided age-specific norms for 500 Hz AC-TBABR and click ABR for ages from newborn (39 to 40 weeks) to 2 to 4 yr. For 500 Hz, mean latencies of 11.13 (Ϯ1.30) for 55 dB nHL and 13.16 (Ϯ1.23) were obtained from 12 infants in the age range of 2 to 4 mo, which compares well with the data in the current study (compare with Table 3 and Fig. 3).…”

AC- and BC-TBABR results can be readily obtained in young infants under natural sleep and were used to classify the type of HL based on the absolute threshold and the size of the ABG. Differences in wave V latency functions for TBABR by AC and BC and wave I and V latencies of the high-level click ABR also distinguish between infants with and without TBABR ABGs. Ear-specific behavioral responses can be obtained at levels under 20 dB HL in normal-hearing infants younger than 1 yr using VRA, and these behavioral thresholds correlate well with TBABR thresholds obtained on average 6.5 mo previously in this population. The current results suggest that protocols for obtaining AC- and BC-TBABR and behavioral thresholds that meet guidelines for early intervention are clinically feasible.

“…The sample of the research was seventy-seven infants and children ranging from conceptional age of 40 weeks (term babies) to 4 years were tested with both click and tonal ABR without any risk factors for hearing loss. Külekçi, et al, (2007)'s results indicate that five hundred hertz of tonal ABR wave V latency did not mature until to 2-4 years old but, click ABR wave V latency reached maturity at the same age range. Researchers have suggested that difficulties with temporal interactions or retrieval may be associated with age.…”

Background: Measuring hearing functional capabilities by Auditory Brainstem Responses (ABR) may contribute to better treatment, and possible differences in this process may have important clinical implications. Objectives: To measure the validity and reliability of ABR through screening, estimating, and intraoperative monitoring auditory capabilities of Arab infants and children and the degree of their seriousness.
