助兴音乐 　　你下次去银行,商店或超市时,停下来听一下你听到了什么?71和你听的音乐很相似,但是不一样.那是因为这个音乐是为了使你感到轻松或给你额外的能量而特别设计的.有时你甚至没有意识到在放音乐,但是不管怎么样你会对音乐有反应. 　　安静的背景音乐常常被叫做“电梯音乐”,因为我们经常在电梯里听见.但是最近我们在越来越多的地方听见了,并且它有了个新名字“Muzak”（录音助兴音乐）.每天大约有三分之一的美国人能听到Muzak,这种音乐每次放15分钟,中间有个短暂停.在上午10-11点,下午3-4点,人们感到疲倦时,它总是更加的充满活力. 　　如果仔细听Muzak,你可能会听出许多歌曲的名字.一些音乐人或曲作家不想让他们的音乐成为Muzak,但是有些人却很高兴他们的音乐被选作Muzak.为什么呢?73 　　音乐经常在公共场所播放,因为当你在机场或饭店时音乐能让你感觉不是很寂寞.已经证实Muzak确实是有这种效果.当听到Muzak时,疲倦的办公室工作人员突然会更有精神.74超市顾客会多买38%的商品. 　　75他们说总听见一样的音乐很令人厌烦.但是有些人喜欢在公共场所听到Muzak.他们说这能让他们感觉放松和安静.无论如何,Muzak影响着每个人.一些农民竟然说他们的牛听见Muzak能产更多的奶.muzak 　　Thenexttimeyougointoabank,astore,orasupermarket,stopandlisten.Whatdoyouhear?71It'ssimilartothemusicyoulistento,butit'snotexactlythesame.That'sbecausethismusicwasespeciallydesignedtorelaxyou,ortogiveyouextraenergy.Sometimesyoudon'tevenrealizethemusicisplaying,butyoureacttothemusicanyway. 　　Quietbackgroundmusicusedtobecalled"elevator(电梯)music"becauseweoftenhearditinelevators.Butlatelywehearitinmoreandmoreplaces,andithasanewname"Muzak".Aboutone-thirdofthepeopleinAmericalistento"Muzak"everyday.Themusicplaysfor15minutesatatime,withshortpausesinbetween.Itisalwaysmorelivelybetweentenandeleveninthemorning,andbetweenthreeandfourintheafternoon,whenpeoplearemoretired.72 　　IfyoulistentoMuzakcarefully,youwillprobablyrecognizethenamesofmanyofthesongs.Somemusiciansorsongwritersdon'twanttheirsongstobeusedasMuzak,butothersarehappywhentheirsongsarechosen.Why?73 　　Musicisoftenplayedinpublicplacesbecauseitisdesignedtomakepeoplefeellesslonelywhentheyareinanairportorahotel.IthasbeenproventhatMuzakdoeswhatitisdesignedtodo.TiredofficeworkerssuddenlyhavemoreenergywhentheyhearthepleasantsoundofMuzakinthebackground.74Supermarketshoppersbuy38percentmoregroceries. 　　75.Theysayit'sboringtohearthesamesongsallthetime.ButotherpeopleenjoyhearingMuzakinpublicplaces.Theysayithelpsthemrelaxandfeelcalm.Onewayoranother,Muzakaffectseveryone.SomefarmersevensaytheircowsgivemoremilkwhentheyhearMuzak!
