“Millions of young people will lose their hearing in five years if they listen to MP3 or MP4 players at a too high voice every day,” scientists say recently.

Do you often listen to MP3 players at a too high voice? Are you frightened to hear this?

The sizes of MP3 players are very small, but small MP3 players make it easy to take hundreds of songs with you. So many young people carry them and listen to music every day. MP3 players are very popular among students. 

The scientists say teenagers should be far from high volume (音量), including mobile phones’ noise. A study says, “High volume and long listening time can cause hearing problems.” They think if young people listen at more than 89 decibels (分贝) every day, they will lose their hearing in five years. A scientist said, “So many young people often use personal music players and mobile phones at a high voice. I am afraid that they may be losing their hearing.

So let’s turn our MP3 players down!
