Researchers claim that finding solutions and remembering things is much easier if your mobile phone is on silent, because ring tones -- and especially catchy songs -- drain your brain power, the Daily Mail reported.

Scientists at Washington University in St Louis found that students scored up to 25 per cent less on tests after being exposed to ringing mobile phones.

The worst results were posted after hearing a song they knew and liked.

The study was published in the Journal of Environmental Psychology.

手機靜音：明智選擇

??????? 據英國《每日郵報》報道，研究人員稱，手機保持靜音，思考問題、背誦記憶將更加高效。各種鈴音，尤其是好聽的歌，會消耗腦力。

???????美國圣路易斯華盛頓大學的科學家發現，學生們若在手機鈴聲泛濫的環境中考試，所得成績會低于實際水平，最多可能下降25%。

???????如果播放他們熟悉和喜愛的歌曲，成績最糟。

???????這項研究已發表在《環境心理學》雜志上。
