Ear buds and headphones can contribute to hearing loss even listening just 15 minutes a day, if the volume is at or above 85 decibels. The louder the sound, the faster hearing damage occurs. Most smartphones and tablets can produce volumes over 100 decibels.
How earbuds and headphones cause hearing damage?
Exposure to loud sounds—at or above 85 decibels—is a leading cause of hearing loss, because it damages the cells of your inner ear. When it comes to noise-induced hearing loss, it all depends on how loud and how long.
Earbuds and headphones sit in or close to the ear canal, which places sound very close to the inner ear. This proximity has the effect of boosting sound by an equivalent of nine decibels. That's like going from a tinkling bell to the drone of a lawn mower. Also, many people boost the volume to block out background noise.
These days, many people wear earbuds for hours on end. Even moderately loud sound can cause hearing damage if you listen for too long. For example, listening to a 90-decibel sound for three hours can be as damaging as hearing a 155 decibel-sound (like a jet taking off) for just thirty seconds.
Remember the 60/60 rule; listen at 60% or the volume just 60 minutes a day.
