People who wear headphones might want to throw them away while walking outside．A study finds that accidents involving walkers （41）Ethe devices have increased three times in recent years．
Researchers searched the National Injury Surveillance System，the U．S．Consumer Product Safety Commission，Google News archives and Westlaw Campus Research，and they found 116 cases of death or injury （42）Bwalkers with headphones．Cases in which people were using mobile phones （including hands-free devices） were not included．
Over the years the number of cases increased，from 16 in 2004 and 2005 to 47 in 2010 and 2011．The victims'average age was 21，and most （68%） were male．The （43）A （ 67% ）  were under the age of 30．Most （55%） were hit by trains，and 70 percent of the crashes，most of which were in urban areas，were （44）H．
In 74 percent of the cases，police or eyewitness reports said the walker had headphones on when hit．And 29 percent of reports made mention of horns or warning bells going off before the crash．

Hearing what's going on in the environment，they point out，could be more important than  （48）Dclues for walkers．But the authors add that this study doesn't show cause or relationship of headphone use and walker risk，and other factors could have been involved in the accidents，such as walkers being intoxicated（陶醉）or drivers being at fault．
More comprehensive information on such accidents is（49）J，the researchers said，to see which groups of people may be most at risk．
