問題詳情

Many people think New York is a noisy city. In fact,scientists who study noisesay that the average noise level in New York is 72. 5 decibels. This is a littlelouder than normal conversation,which is 65 decibels. The noise level is the resultof so many people and cars in the same area.Now even the insides of taxis are noisy. When you get into a taxi,you hear the voiceof a wellknown singer,sports reporter,or Broadway actress giving instructions.That’t right. The voice of a famous person tells you what to do. One popular singergives this message:“Cats have nine lives,but you have only one,so fasten your seatbelt!”Other voices say things such as“Don’t forget to collect all yourbelongings. ”（People often leave hats,umbrellas,and bags in taxis. ）There is a good reason for the messages. There are more than 12,000 cabs in NewYork,and every year taxis get into more than 15,000 accidents. In an accident,peoplewho don’t wear seat belts hit the partition,the glass wall separating the driverand passengers in the taxi. They can hurt their foreheads or break their noses orchins. Every year,about 11,000 people are injured in this way.Many people are annoyed by the voices. Cabdrivers in particular dislike themessages. “I play the messages 12 hours a day. I hear the same voices 60 times aday. It makes me crazy,”says Amir,a 45yearold cabdriver. “But if I don’t play themessages,I get fined ＄100. ”A lot of passengers complain,too. “It’s too muchnoise,”says a passenger. “I asked the driver to turn off the message,but he saidhe can’t. ”Other people think the voices are a great idea. One taxi driver says,“People liketo hear the famous voices,and they put on their seat belts more often. ”Andpassengers from out of town really like the idea. “Most of the time,taxi driversare in a bad mood,”says Melanie Benton,who visits New York often onbusiness,“It’s nice to hear a cheerful voice when you get into a cab. ”
