Detailed explanation-1: -Headphones cause damage to your ears the same way other loud noises do, resulting in what audiologists call “noise-induced hearing loss.” Over time the sounds from your headphones cause the hair cells in the cochlea to bend down too much or too severely. If they don’t get time to recover, the damage can be permanent.
Detailed explanation-2: -Overuse of headphones may cause permanent hearing loss by damaging the hair cells of the inner ear and the auditory nerve. People must take breaks when using headphones. They should also avoid exposure to noise above recommended levels.
Detailed explanation-3: -Headphones and earbuds can cause noise-induced hearing loss (NIHL), but it’s easy to avoid. Volume and exposure time are the two key factors in NIHL. Any noise louder than a vacuum cleaner at 75dB(SPL) can threaten your hearing.
Detailed explanation-4: -Normal use of in-ear devices don’t often cause a problem. But prolonged earphone use, such as if you leave them in all day, could: compress the earwax, making it less fluid and harder for the body to naturally expel. compact the earwax to the extent the body induces inflammation.
Detailed explanation-5: -The right headphones can also make a difference. Although earbuds are popular now, I’d caution against using them too excessively, for a few reasons. First, because they deliver sound directly into the ear canal, there’s a much greater risk of damaging your ears if the volume gets too loud.
