1.Have you noticed the number of people listening to music very loudly on the trains and buses?Their music is so loud that you can even hear clearly what the singers are singing.The problem is that the music is coming out from their earphones!Doctors warn young people about the dangers of listening to music from earphones so loudly for a long time.In the United States,studies show that musicians and people who work at performance halls have experienced hearing problems after exposure (暴露) to loud music for just up to 30 minutes a day.These people slowly lose their hearing and need to turn up the music even more loudly to hear it properly,possibly causing further damage to it.
As we know,the ear has three parts-the outer part,the middle ear and the inner ear.There are tiny hairs in the inner ear.It is the tiny hairs that receive the soundwaves and then change them into what the brain (脑) can understand.Exposure to loud noise can damage the tiny hairs and this causes hearing loss (损伤).Usually,this kind of hearing loss can be treated if the noise isn't very sudden and loud.Exposure to loud noise for too long a time can cause lasting damage.People with serious hearing loss may need to have an operation,but even after the operation they may not hear as well as before.
You know you have been listening to loud music too long when you start hearing ringing noises in your ear.They may be signs that the tiny hairs in your inner ear have been damaged.
So next time you listen to music using your earphones,make sure it is not loud enough for others to hear.Remember that once hearing loss sets in,there is no turning back.
