Since the beginning of the COVID-19 pandemic, there have been reports on the possible hearing loss caused by the disease. A new study finds no evidence of damage to the auditory system as a result of COVID-19 infection.

Participants included eight asymptomatic individuals who had tested positive for COVID-19 and eight healthy volunteers who served as a control group, none of whom reported any previous hearing loss. The study provided for the first time quantitative measures for hearing quality following exposure to the virus.

The team measured electrical data from the brainstem to test the entire route of soundwaves through the ear until electric waves are ultimately received in the brain. They also examined the activity of the inner ear hair cells that intensify and tune the sound and found no difference between the COVID-19-positive subjects and the control group.

This study proposes that the COVID virus does not cause extensive neurological damage but is rather spotty, mostly affecting the sense of smell. Moreover, the hearing impairment among some patients is mostly transient and secondary to fluid buildup in the middle ear, as for the common cold, and therefore likely passes once the acute disease is over.
