Do you often listen to music at loud volumes（音量）？ Over one billion（十亿） young people are at risk of hearing loss （失聪）because of listening to loud noise for long periods of time．Listening to music or watching a TV show at loud volumes is harmful to your hearing．

The United Nations has standards for safe listening． It is not safe to listen to sounds that are louder than 85 decibels（dB 分贝） for eight hours or 100 dB for 15 minutes． The sound of a busy road is about 85 dB and the sound of a rock concert can be about 100 dB．

Loud noise is harmful to the inner ears（内耳）． most of us are born with about 16，000 hair cells（听毛细胞） in our inner ears． However， listening to loud noise for a long time can make these cells work too hard and cause some of them to die． This is what causes hearing loss．

Some people might think that their music isn't all that loud． But this can depend on where you are． For example， if you are in a noisy place like the subway， you might turn up your music too loud without realizing it． Later， when you listen to it at the same volume in a quiet place， you might feel uncomfortable．

The World Health Organization said the"safe level" for most sounds is below 80 dB for up to 40 hours a week． A level of 80 dB is roughly equal to（大约相当于） the noise of a subway．

Imagine a perfect day： the weather is good and everything seems fine． When， suddenly， your mobile phone loses its signal， the television has no programs， and you can't get online with your computer．

What has happened？ These are just the types of problems a solar storm（太阳风暴）might cause． You may not think of storms as putting our society in danger． But today， a solar storm is as serious as other bad events， such as earthquakes．

A solar storm is caused by solar flares（太阳耀斑）： large explosions（爆炸）near the sun that can give off lots of energy． The strong energy can stop the satellite systems（卫星系统）that control our computers， telecom networks and so on． These storms can even cause the power to go out for weeks or months．

In the past few months， scientists have recorded some of the strongest sun flares in years． The most recent one happened around Valentine's Day， 2011． It caused radio and satellite signals to go down in some northern cities in China．

"Solar flare activity is going to be much worse than what we've seen in the past． We're not talking about a few cities losing power， it could be half of the country， maybe more．" SolarStorm Warning．com， a US website about space weather， warned．

Scientists say that little can be done to predict such a storm． Governments around the world are trying to work together before the next storm， although they are not sure when that may happen．
