ESTUDO DAS EMISSÕES OTOACÚSTICAS - PRODUTO DE DISTORÇÃO DURANTE A PRÁTICA ESPORTIVA ASSOCIADA À EXPOSIÇÃO À MÚSICA.

Purpose: to study the hearing of individuals in a fitness gym while exercising, analyzing their distortion product evoked otoacustic emissions (DPOAE) test after and before exposure to electronically amplified music. Methods: a questionnaire was applied to 20 individuals and evaluated through DPOAE test after and before physical exercises with electronically amplified music exposure. Results: most of the individuals (65%) had extra-occupational exposure. The most frequent complaints were headache and insomnia (40%); hearing difficulty (35%); aural fullness (25%); irritability and nervousness (25%); dizziness (20%); and tinnitus (15%) after exercises. Although DPOAE occurred in 100% of the ears before the exposure (moment 1 - M1), 25% failed on the second test, after the exercises (moment 2 - M2). The frequencies that most failed in the DPOAE test were 3 KHz, 4KHz and 5KHz. Conclusion: this study shows that individuals exposed to electronic amplified music, may have hearing loss complaints and have signs of such loss. [ABSTRACT FROM AUTHOR]
