PURPOSE: to compare the findings of TEOAE with tympanometry in 226 and 1000 Hz in infants. METHOD: the study was conducted in the Department of Otolaryngology, Hospital Santa Juliana Maceio - Alagoas. We selected infants of both genders, aged from newborn to six months. We excluded those with cleft palate, external and/or middle ear malformation, syndromes, and family history of hearing loss. The following procedures were conducted: anamnesis in order to identify hearing impairment and to select the sample according to the criteria of inclusion and exclusion; otorrinolaringological assessment using otoscopy and hearing evaluation that consisted of transient evoked otoacoustic emissions (TEOAE) and tympanometry with 226 and 1000Hz probe tones. In order to analyze the qualitative variables, we used the test for Equality of Two Proportions, and the Chi-Square for Independence and the confidence interval for the average used for the analysis of the results of quantitative variables. RESULTS: comparing the results of TEOAE with the tympanometry results that were obtained with 226Hz and 1000Hz probe tones, we observed an association of TEOAE with the 1000Hz probe for both ears, the infants with TEOAEs absence had altered tympanogram results and the ones where the TEOAEs were present had normal tympanograms. CONCLUSION: There was a higher correlation between the results of the 1000 Hz probe tympanometry and the TEOAE in order to identify normal ear responses and middle ear disorders.
