The conclusion of that study was that more research was needed and that the best would be to incorporate increased hygiene measures such as regular cleaning of the headphone to prevent a build-up of bacteria or fungus that can cause external canal infections as well as discouraging the sharing of headphones. The study, however, did have some flaws as the employees weren’t screened when they were first appointed, so there is no way of knowing if the employees with chronic ear infections perhaps got them while on duty. It did, however, make the symptoms worse in individuals who already had chronic middle ear infections. While this is theoretically true, a study on ear infection and hearing loss amongst headphone users found that prolonged use of headphones by call center attendants predisposes them to infection of the external ear canal. This creates the ideal environment for both introducing bacteria to the ear canal as well as promoting their growth. Yes, headphones can increase the temperature of the ear canal and, when worn for extended periods of time, can lock in humidity. Earphones seem a likely culprit, but : Can headphones cause ear infections?
A friend of mine recently got an ear infection, it wasn’t the worst, but as we were both constantly using our headphones, it popped up in conversation if the cause could be her headphones.
