交通噪音可能会缩短寿命

　　Traffic noise can shorten your life, new research suggests. Having to endurerumbling1 lorries, honking2 horns and screeching3 tyres has been linked to shorter life expectancy4 and a higher risk of stroke.

　　一项新研究表明，交通噪音可能会让你的寿命缩短。长期忍受隆隆响的卡车声、哔哔的喇叭声、尖锐的轮胎声，容易缩短寿命，增加中风的风险。

　　People surrounded by daytime traffic noise louder than 60db were 4 per cent more likely to die than those where noise levels were 55db – roughly the level of a loud conversation.

　　The extra deaths mostly involved heart or artery5 disease - which could in turn be linked to raised blood pressure, sleep problems and stress brought on by noise, the scientists claim.

　　A total of 8.6 million living in London between 2003 and 2010 provided data for the study, reported in the European Heart Journal.

　　Lead scientist Dr Jaana Halonen, from the London School of Hygiene6 & Tropical Medicine, said: 'Road traffic noise has previously7 been associated with sleep problems and increased blood pressure, but our study is the first in the UK to show a link with deaths and strokes.'

　　In London, more than 1.6 million people are exposed to daytime road traffic noise louder than this threshold.

　　The study also found that adults living in areas with the noisiest daytime traffic were 5% more likely to be admitted to hospital for stroke than those from quieter neighbourhoods. For the elderly, this increase in risk rose to 9%.
