　　Every year television stations receive hundreds ofcomplaints about the loudness of advertisements. However. federal rules forbid the practice of makingads louder than the programming. In addition, television stations always operate at the highestsound level allowed for reasons of efficiency. According to one NBC executive. no difference exists in the peak sound level of ads andprogramming. Given this information. whydo commercials sound so loud?

　　The sensation of sound involves a variety of factors in addition to its peak level. Advertisersare skilful at creating the impression of loudness through their expert use of such factors. Onemajor contributor to the perceived loudness of commercials is that much less variation insound level occurs during a commercial. In regular programming the intensity of soundvaries over a large range. However, sound levels in commercials tend to stay at or near peaklevels.

　　Other "tricks of the trade" are also used. Because low-frequency sounds can mask higherfrequency sounds. advertisers filter out any noises that may drown out the primarymessage. In addition, the human voice hasmore auditory (听觉的) impact in che middlefrequency ranges. Advertisers electronically vary voice sounds so that they stay within sucha frequency band. Another approach is to write the script so that lots of consonants(辅音) are used, because people are more aware of consonants than vowel (元音) sounds. Finally, advertisers try to begin commercials with sounds that are highly different from those of theprogramming within which the commercial is buried. Because people become adapted to thetype of sounds coming from programming. a dramatic change in sound quality draws viewerattention. For example. notice how many commercials begin with a cheerful song of sometype.

　　参考答案：

　　1.[A]第1段2句和第4句分别提到，联邦法律禁止广告声音大于节目的声音;国家广播公司的某个官员称，广告和节目的最大音量并无区别。由此可知，广告的声音强度并没有超过节目，因此A正确。

　　2.[B]第2段第1句指出，人们对声音的感觉会受音量峰值的影响，后面进一步说明为达到此目的，广告人使用的技巧。再结合本段最后一句，可知B项符合题意。

　　3.[C]第3段例数第2句提到，人们已经适应了节目中传来的那种声音，因此很多广告使用欢快的歌曲作为开头，希望以声音的强烈变化吸引观众的注意力。C正确，其他选项没有原文依据。

　　4.[D]第3段指出，广告人采用与节目明显不同的声音制作广告以吸引人们的注意力。最后一段也指出广告独特的音质能立即吸引人们的注意,因此D正确。A是将音量保持到最高的技巧，因而与题意不符;C明显与文中的表述相悖;B不能由文章推出。

　　5.[D]询问文章主旨。从全文来看，作者一开始就提出“为什么商业广告的声音听起来那么大”的问题，然后剖析其中的原因，说明技术人员是怎样利用有特质的声音来制作广告的。因此，D正确。
