Noise pollution is doing much harm to our health now．Noise is a kind of invisible(无形的)killer．More and more students enjoy listening to music very much．When they listen to MP3 players，they like to turn up the volume(音量)．While watching TV，they keep the volume up．But they haven’t realized that the noise is weakening(减弱)their hearing．In fact，the noise not only influences each member in the family，but also influences the neighbors．

Noise pollution is a source of misery to people in our society．If people are often disturbed by it，they may feel uncomfortable or sad．What’s worse，the noise can make people mad sometimes．If a worker works in a printing factory for too long，his hearing loss is much faster than a common person working in a quieter environment．So everybody must pay attention to noise pollution．

The following simple ways can be used to avoid(避免)noise：

★Try to use less noisy equipment(设备)(e．g．washing machines)．

★Keep the volume of TV，radio and music as low as possible，especially late at night．

★If your dog barks when left alone，make sure to leave it with a friend．

★If you have a party，tell your neighbors in advance(提前)and keep the noise a little lower．

I think the local environment protecting department(部门)will take measures to control the noise levels．But it’s everybody’s duty to keep a quiet environment．
