The British Medical Journal published a study which showed that 1 billion young people were at risk of hearing loss.

Researchers shared their analysis of data from 2000 to 2021 on unsafe listening practices. If the volume is too loud for too long, headphones, a concert, or even a restaurant could cause irreversible damage. Young people are complaining about persistent ringing in their ears, although their hearing tests look normal. However, several years later, their hearing reduces.

The loud sounds damage sensory cells in the cochlea, the snail-looking part in the inner ear. Once these cells die, you can’t get them back. 85 decibels sound like a blender, 100 decibels sound like a subway train, and 120 decibels sound like a concert or a siren.

According to experts, 85 decibels during a 40-hour work week is the maximum safe limit. Just 2.5 hours of 92 decibels can damage your ears. However, only one episode of intense noise exposure can lead to lifelong hearing loss.

Difficult words: irreversible (impossible to change or return to a previous condition), persistent (continue over a long period of time), exposure (affected by something).
