The World Health Organization wants to limit noise levels in nightclubs to stop millennials going deaf. Some 466million people already have debilitating hearing loss, up from 360million in 2010. William Shapiro, a clinical associate professor at New York University Langone, explained in January 2018 that damaging the inner-ear's hair cells is how headphone-related hearing loss begins. These tiny, sensory hair cells are crucial to helping us detect sound waves – but are very fragile. The hair cells do not regenerate, so damage to them is permanent — a common cause among people with some types of hearing loss.
