sound signals by as much as six to nine dB•
Indian Council of Medical Research (ICMR) reported 10.7% of population
suffering from hearing impairment is due to earphone use

themselves at risk for permanent noise induced hearing loss if
exposed for extended periods of time (years).
• These results are alarming as more and more children are using PLDs

30. • Hearing loss induced by personal listening devices (PLDs)
• may evolve into a significant social and public health problem
• in future years.
• Prolonged exposure to loud music leads to a
significant/subclinical damage to hair cells of the cochlea

• Ear infections due to use of earphones
sharing earphones with others is definitely not safe as the bacteria from
other s ears travel to your ears and cause infections.
• Blockage of air passage
• Side effects on brain
