ABSTRACT

Background: The visual reinforcement audiometry and steady-state evoked potential are tests that allow to identify auditory thresholds.
Objective: To compare the date obtained throw the visual reinforcement audiometry and the steady-state evoked potential in the determination of the auditory threshold in pediatric patients.
Material and Method: A cross-sectional, comparative, observational and descriptive study was done from February to September 2017 in children participating in a visual reinforcement audiometry and a steady-state evoked potential in 500, 1000, 2000 and 4000 Hz. Descriptive statistic tests and error graphs were also performed to evaluate the trend of the data, t-Student test to determine significant difference for samples related to p ‹ 0.05, confidence intervals for the mean and probabilistic intersection of AB.
Results: In most evaluations, the values are inverse with respect to the averages and standard deviations. The highest correlations were found in the frequency of 2000 Hz with TDH39. The probability of greater coincidence between both tests with TDH39 and free field was found in the right ear at the frequency of 500 Hz.
Conclusion: It is necessary to perform the visual reinforcement audiometry in a random way in both ears and evaluated frequencies in order to obtain specific results in the auditory threshold determination, as well as to try to ensure an adequate previous conditioning.
