supermarkets, department stores… Background music is supposed to influence (影响) your attitudes
(态度) and mood (心情).
     Companies pay millions of dollars every year for background music. It's supposed to make you feel
better about yourself and the people around you. Factories use it a lot. It makes the workers happy and
work better. It is said (据说) that in a factory, music can increase the production by 4.5 percent.
Workers do not easily get tired if they listen to music all day. A worker in San Francisco said:" If the
music stops, somebody always runs to the telephone to complain about it. "Background music was
started during World War II when some factories had their own orchestras to keep workers happy and
calm . Now, of course, the music is piped in (以电讯设备传送) by a machine and different kinds of
music are played at different time in a day. For example, the music they play are faster at 10 than 8,
because workers are usually slower then.
     It's also very interesting that fast music is played in restaurants where hamburger is sold. Before
playing fast music, customers spent 22 minutes eating hamburgers. When they started playing fast music,
they found that a customer spent only 17 minutes eating! So they have more people coming in and out to
buy hamburgers. It's good for business. You can see why music has become so popular. In Los Angeles
(洛杉矶), for example, 30 different companies are selling background music services.
     The Xerox Corporation (静电复印公司) in Rochester, N.Y.(纽约州的罗切斯特市), spends
more than $80,000 a year for background music. Prison warders (狱警) use it. Farmers also use it to
