Background: Early identification of hearing loss and early intervention are crucial to maximize the develop-ment of receptive and expressive language abilities and communicative experience. Therefore, the need for uni-versal newborn hearing screening has been ratified by the Joint Committee on Infant Hearing. Objective physiolog-ical techniques which are not influenced by sleep or seda-tion, have to be applied to be able to provide adequate in-tervention before 6 months of age. Auditory steady-state potentials evoked by amplitude modulated noise or tran-sient stimuli might be useful in providing rapid and objec -tive tests of hearing during screening procedures.Objective: The aim of this study was to evaluate the use of auditory steady-state evoked potentials with white noise stimuli as a screening tool. Method: This study was approved by the Human Re-search Ethics Committee. The population of the study was composed of 30 newborns. The equipment used in the study was the MASTER. The stimuli was white noise amplitude modulated between 80 and 110 Hz, the elec-trodes position were: FZ active, M1 reference and M2 ground. All stimuli were presented at 40 dBSPL to 70 dB-SPL intensities. The ears were recorded simultaneously.Results: The data was inserted in Microsoft Ex-cel 2002 for Windows program, were analyzed speci-ficity, sensibility and likehood ratio. For the intensity of 50dBSPL considered as the point of pass-fail, the results for sensibility were 100%, specificity: 100% and LR+: ∞, which shows a near relation between ASSR screening and the gold standard assessment. There was a high fail index (10%), probably because were evaluated high risk children with risk factors for hearing loss (prematurity and low-weight), and the media of age was 28 days, its known that in this age, changes in ear canal-recorded sound levels across the assessment period can be observed, what may reflect differences in ear canal volume, canal resonance and middle eat mechanical properties.Conclusion: This work showed that the use of audi-tory steady state with white noise in hearing screening is possible, and a alternative tool for hearing screening as-sessment. Clinical application of the ASSR procedure in the neonatal population will need to take into account de -velopmental changes occurring in the first weeks of life. More studies have to be made to solidify these findings.Key words: auditory, steady state, hearing screening, white noise.
