Despite the multitude of ongoing research studies on COVID-19, there are many unknowns about the disease. What is known, however, is that it is more than just a simple lung infection.
Current research suggests that the respiratory system is not the lone organ system bearing long-term effects from the disease. COVID-19 may impact cardiovascular, immune, and nervous systems. Coronaviruses also may cause peripheral neuropathy or Guillain-Barré syndrome, both of which could result in auditory neuropathy.
At this time, there is limited research related to COVID-19 and hearing loss. However, Kevin Munro and colleagues conducted a systematic review with current evidence and report some patients experience hearing loss and tinnitus.
Although their data have not been published, Munro reports that 3 of 25 COVID-19 patients who were discharged from a hospital reported hearing problems. At this time, there are no data examining the potential long-term effects of COVID-19 on hearing sensitivity. As a result, it will be important for audiologists to stay tuned for up-to-date literature on the short and long-term impacts of COVID-19 on hearing.

Lack of Physical Activity and Obesity in Individuals with Self-Identified Hearing and/or Visual Difficulties
It is reasonable that lack of physical activity would be one thing associated with obesity, but could difficulties hearing and/or seeing also be a factor influencing that relationship? What about gender? Pardhan and colleagues (2021) used data collected from the 2017 Spanish National Health Survey to evaluate the relationship between physical inactivity and obesity by…
Do you remember why Joseph Sauveur is important to our profession? If you do, you could have done better than a recent contestant on the legendary gameshow, Jeopardy. The question posed was: “Born hearing-impaired in 1653, Joseph Sauveur studied sound vibrations and coined this word for the science he pioneered.” While I was impressed that…
Sudden sensorineural hearing loss (SSNHL) can occur with or without symptoms of vertigo/vestibular dysfunction. In a recent study, investigators sought to determine the contribution of audiogram classification when evaluating vestibular dysfunction in those with SSNHL. A total of 50 subjects who had experienced SSNHL were divided into two groups, one without vertiginous symptoms and one…
