Background:
Coronavirus disease 2019 (COVID-19) and its effects on hearing performance have been an interesting topic for researchers recently.
Purpose:
The objective of this study was to assess the audiological profile of people affected by COVID-19 and also to compare them with a control group who has never had COVID-19.
Research Design:
An experimental study.
Study Sample:
The study group consisted of 54 participants, aged 18 to 60, who were diagnosed with COVID-19 by polymerase chain reaction and recovered at least 2 months prior to audiological assessment. The control group consisted of 60 subjects in the same age range who did not have a history of COVID-19 or hearing loss.
Data Collection And Analysis:
Post-COVID audiological data were compared. The pre-COVID-19 audiological data of 43 subjects in the study group were also compared with their post-COVID-19 data. All participants were evaluated with pure tone audiometry, acoustic immittancemetry, speech audiometry, and high-frequency audiometry.
Results:
Pure tone hearing thresholds, speech recognition and discrimination scores, and high-frequency hearing thresholds were all statistically different between the study and control groups (p < 0.05). There were statistically significant differences between the study group's pure tone hearing thresholds before and after COVID-19 (p < 0.05).
Conclusion:
COVID-19 can adversely affect hearing performance. Further studies including auditory brainstem response, otoacoustic emissions, and similar cross-check tests are needed to reveal further effects of COVID-19 on hearing.

Pulmonary Function Tests
Pulmonary Function Tests are crucial diagnostic tools for assessing respiratory function, particularly in patients with chronic respiratory disorders. They comprehensively evaluate lung volumes, ventilatory function, breathing mechanics, diffusion, and gas exchange. These tests help diagnose pulmonary diseases and play a significant role in monitoring disease progression, evaluating disability, and assessing response to therapy.
