Background music may seem harmless, but it can have a powerful effect onthose who hear it. Recorded background music first found its way into factories,shop and restaurants in the US. But it soon spread to other arts of the world.Now it is becoming increasingly difficult to go shopping or eat a meal withoutlistening to music.

To begin with, "muzak" (音乐广播网) was intended simply to create a soothing(安慰) atmosphere. Recently, however, it's become big business -thanks in part torecent research. Dr. Ronald Milliman, an American marketing expert, has shownthat music can boost sales or increase factory production by as much as athird.

But, it has to be light music. A fast one has no effect at all on sales.Slow music can increase receipts by 38%. This is probably because shoppers slowdown and have more opportunity to spot items they like to buy. Yet, slow musicisn't always answer. Dr. Milliman found, for example, that in restaurants slowmusic meant customers took longer to eat their meals, which reduced overallsales. So restaurants owners might be well advised to play up-tempo music tokeep the customers moving - unless of course, the resulting indigestion leads tocomplaints!
