Introduction: The World Health Organization reports an incidence of hypoacusis of 5/1000 live births; 2.1% of the world population suffers from a hearing deficit. In Mexico, the Human Communication Institute of the Ministry of Health estimates that 5,600 are born with hearing loss per year. Undiagnosed hearing loss has adverse effects on language, social, emotional, cognitive, academic and professional development. Objective: To verify the sensitivity and specificity of Hearing Otoacoustic emissions in healthy newborns without risk factors. Material and Methods: Prospective study with a probabilistic, descriptive, transversal, quasi experimental and analytical design. We studied 815 healthy newborns without risk factors. EOA and Brainstem Auditory Evoked Potentials were performed with the BERAphone equipment. Sensitivity, specificity, Negative Predictive Value and Positive Predictive Value were determined, using the ROC curve. The AUC value was determined, Pearson’s X2 test was used, and Fisher’s Exact Test was used for the distribution of both tests. Results: 1630 auditory tests were performed. A sensitivity of 63.64% and a specificity of 98.95%, an AUC of 0.805%, VPP 29.17% and VPN 99.75%, LH +60.60% and LH -0.37% of all the tests were detected. The right ear had a sensitivity of 40.0% and a specificity of 98.64%; In the left ear sensitivity of 83.33% and specificity of 99.26%. Conclusions: Otacoustic emissions in newborns without risk factors have a regular sensitivity and high specificity.
