Introduction: The Automated Auditory Brainstem Response (AABR) is an important tool to make Newborn Hearing Screening. However, some aspects that make it more difficult to exam, like time and intensity of acoustic stimulus, must be taken into consideration. Aim: Analyze the results of Newborn Hearing Screening with Automated Auditory Brainstem Response with new technologies that use the detection method in the frequency domain and stimulus repetition rate at 93Hz. Methodology: The Automated Auditory Brainstem Response was made at 200 newborns (93 female and 107 male), at 30 and 35dBnHL. Subsequently all newborns were submitted to the Auditory Brainstem Response (ABR) Diagnostic Mode, as golden standard test. Results: The sensibility and specificity were calculated through Fisher Exact Test taken into consideration the ABR Diagnostic Mode. The sensibility found at AABR at 35dBnNA was 100% and the specificity was 100%, at the intensity of 30dBnNA the sensibility found was 100% and the specificity was 97.23%. The average time to make the automated exam was 28.3 seconds in the 35 dBnHL and 32.9 seconds in the 30 dBnHL. The time was analyzed considering the state of consciousness of the newborn, based on the Brazelton Scale classification. It was possible to notice that when the newborn was quieter the examination time was quicker. Conclusion: The AABR made at frequency domain with stimulus repetition rate at 93Hz shows high sensibility and specificity, with relative short time to get the results. The state of consciousness influences the execution time of the exam.
