Resumen:
Introduction: The most common cause of tinnitus is theexposure to noise; in the case of adolescents, music is the main sound sourcethey are exposed to. Currently, one of the hypotheses about the genesis oftinnitus is related to the deterioration in the functioning of the medialolivocochlear system (MOCS). Aim: The aim of this study was to determine thepresence or absence of tinnitus in adolescents with normal hearing and torelate it to: (a) the functioning of the MOCS, by the contralateral suppression(CS) of the transient evoked otoacoustic emissions (TEOAEs), and (b) themusical general exposure (MGE). Materials and Methods: A cross-sectionaldescriptive correlational study was conducted. The sample was composed byadolescents with between the ages ofbetween 14 and 15. Two questionnaires wereadministered, one in relation to the subjective report of tinnitus, and theother in relation to recreational activities to know the MGE. Results: Theresults showed that the amplitude of frequencies (1000, 1500, 2000, and 3000Hz) Hz and global amplitude of TEOAEs, with and without acoustic contralateralstimulation, was were higher in the group without tinnitus, with astatistically significant difference (p P < 0.05). The suppressive effectwas higher in the group without tinnitus; however, there was no statisticallysignificant difference. On the other handContrastingly, a significantassociation (p P < 0.05) between exposure to music and tinnitus wasobserved; 72.41 % of the adolescents with high exposure to music had tinnitus.Discussion and Conclusion: The results of the present investigation provide acontribution to the hypothesis of ?the participation of the MOCS?.?Furthermore, a high MGE can be considered a risk factor for the onset oftinnitus.
