Interesting - one of the links you posted earlier today mentioned that someone was having clumsiness issues...
Right, both hearing and balance depend on the inner ear, so these might indicate the virus having an effect there.
The last paragraph of the article I linked is encouraging:
Whether the hearing dysfunction persists for an extended period is not known due to the scar[c]e research on this matter; only three small studies so far. If the trend also follows other viruses, then the Covid-19-related hearing loss should not be permanent. “Most cases of sudden hearing loss are viral, and most patients are treated with steroids,” New York otolaryngologists at Icahn School of Medicine at Mount Sinai explained. “Patients with mild degrees of hearing loss usually recover.”
