Ahead of World Hearing Day, experts have urged everyone to get themselves checked to prevent unsafe listening practices, with the World Health Organisation (WHO) estimating a rising trend of hearing impairment across the globe.
"Earlobes have two important functions - localisation of sound and reflecting the unwanted sound. Using earphones, one bypasses them. We think we are hearing very well, but today's earphone users are going to be tomorrow's hearing aid users," said Sudipta Chandra, ENT, head and neck cancer specialist.
However, there is no significant study that can provide a fixed duration of hours of earphone usage that is safe. Using headphone and portable speakers are fine if the volume is below 85 decibels.
As per a WHO estimate, there were 466 million persons in the world with hearing loss in 2018 and the figure is likely to increase to 630 million by 2030. Also, 1.1 billion young people are at risk due to unsafe listening practices.
"This year's theme of World Hearing Day is 'check your hearing'. People should act immediately as loss of hearing is preventable, curable and treatable," another ENT specialst M.N. Bhattacharya said on Thursday.
