参考译文:如果你总是幻听,可能是因为咖啡喝得太多。研究人员称,一天5杯咖啡就能让你的耳朵不灵便。在一次试验中,饮用了“大量”咖啡因的志愿者认为自己听到了宾·克罗斯比唱的《白色圣诞节》,而事实上这首歌并没有播放。研究人员称咖啡因是“最常被使用的精神药物”。他们还称该研究表明,过量饮用咖啡导致的健康风险亟待解决。在测试中要求92名志愿者听一段不间断的白嗓音(用以掩盖令人心烦的杂音的声音)。 If you always listen, it may be because you drink too much coffee. Researchers say 5 cups of coffee a day can make your ears inconvenient. In one trial, volunteers who had consumed a lot of caffeine thought they had heard “White Christmas” sung by Bin Crosby, and the song was not actually played. Researchers call caffeine “the most commonly used psychotropic drug.” They also said the study shows that the health risks posed by over-consumption of coffee are urgent solutions. 92 volunteers were asked during the test to listen to an uninterrupted white voice (to cover up the annoying noise).
