Experts say that more than 1 billion young people cannot hear well.

They are between 12 and 34 years old. Young people often hear a loud continuous noise in their ears. Their hearing tests look normal. Later, their hearing test results are worse.

Experts know reasons why this situation happens. Young people listen to their headphones. They go to concerts. The music is too loud. Sometimes, music in restaurants is loud, too.

Decibels tell us how loud something is. The sound of a food mixer is 85 decibels. The sound of a train is 100 decibels. Experts say that it is safe to listen to 85 decibels at work.

Sometimes we can lose hearing when we hear something very loud only once. Loud noise kills the cells in our ears. We cannot fix the situation.

Difficult words: result (the information we get from a test or experiment), headphones (a device which people wear over their ears to listen to music), cell (the smallest part in the human body).
