Abstract
ABSTRACT Purpose: to verify the auditory acuity and correlate auditory thresholds of pure tone audiometry (PTA) with transient-evoked otoacoustic emissions (TEOAE) and distortion-product otoacoustic emissions (DPOAE) in post-COVID-19 adults. Methods: an analytical cross-sectional study, conducted between October 2021 and October 2022, with 63 post-COVID-19 adults (age range 20-53 years old). The following were performed: PTA, TEOAE, and DPOAE. The results were presented descriptively, and Spearman’s correlation test was used. Results: no hearing loss was identified. Most frequency bands were present in both emissions tests. There was a negative and significant correlation between the PTA and TEOAE thresholds in the frequency bands of 500-1500 Hz and 1500-2500 Hz on the left and between the PTA and DPOAE thresholds in the frequency bands of 1000, 2000, and 4000 Hz on the right and 1000, 2000, 3000, 4000, 6000, and 8000 Hz on the left. Conclusion: post-COVID-19 adults presented auditory thresholds within normal limits, with a response to TEOAE and DPOAE. There was a negative correlation between TEOAE and DPOAE and the PTA air threshold, indicating that higher PTA thresholds are associated with lower emission response amplitude.
