Truth: Headphones or hearables can lead to permanent hearing loss.
According to a 2011 study published in the Journal of the American Medical Association, the prolonged use of headphones and earbuds has led to a major increase in the prevalence of hearing loss in adolescence and young adults. Having a sound projected directly into your ear canal can increase a sound’s volume by 6 to 9 decibels — enough to cause some serious problems. Not only can the inner ear be damaged by the loudness of noise, but it can also be damaged by the length of exposure. If the ear is not given enough time to recover between episodes of noise exposure, permanent damage can occur.
