Psychologists now believe that noise has a considerable effect on people’s attitudes and behavior. Experiments have proved that in noisy situations (even temporary ones ), people behave more irritably and less cooperatively; in more permanent noisy situations, many people cannot work hard, and they suffer from severe anxiety as well as other psychologecal problems. However psychologists distinguish between“sound”and “noise”.“Sound”is measured physically in decibels.“Noise”cannot be measured in the same way because it refers to the psychological effect of sound and its level of “intensity”depends on the situation. Thus, for passengers at an airport who expect to hear airplanes taking off and landing, there may be a lot of sound, but not much noise (that is, they are not botered by the noise). By contrast, if you are at a concert and two people behind you are whispering you feel they are talking noisily even if there

Passage Four
Unwanted sound, or noise, such as that produced by airplanes, traffic, or industrial machinery, is considered a form of pollution. Noise pollution is at its worst in densely populated areas. It can cause hearing loss, stress, high blood pressure, sleep loss, distraction (注意力分散), and lost productivity!
Sounds are produced, by objects that vibrate (振动), at a rate that the ear can detect. This rate is called frequency and is measured in hertz (赫兹), or vibrations per second. Most humans can hear sounds between 20 and 20,000 hertz, while dogs can hear high pitched sounds (高频声音) up to 50,000 hertz. While high frequency sounds tend to be more hazardous (危险的) and more annoying to heating than low frequency sounds, most noise pollution damage is related to the intensity of the sound. Measured in decibels (分贝), noise intensity can range from zero, the quietest sound the human ear can detect, to over 60 decibels. Conversation takes place at around 40 deci
A. In streets.
B. In airports.
C. In subway stations.
D. In concerts.
