Could you stand the noise of a street-sweeper truck going up and down the street outside of your house three times a week at 4 a.m.? The noise —described by Blomberg as “loud as a NASCAR(全国赛车联合会) race car but at a speed of 5 miles per hour” — annoyed him so much that he tried to persuade the city to reschedule street sweeping to begin at 6 a.m. He also founded the nonprofit Noise Pollution Clearinghouse, an organization that provides research and information to others whose request for quiet might otherwise fall on deaf ears.
Hearing loss, in fact, is the most obvious medical consequence of noise pollution, but it is hardly the only one, explains environmental psychologist Arline Bronaft. In her research, Bronzaft found that constant noise exposure could reduce children’s learning ability and cognitive(认知的) development. Beyond all that, regularly, “you’ve got to take a break
from sound,” says Bronzaft.
The bad news, says Blomberg, is that “the last century was the noisiest in history.” The good news, he continues, is that the greener we get, the quieter we’ll also get. Electric cars and lawn equipment, for instance, make less noise, just as more fuel-efficient vehicles do. Improved technology can also provide measures to make the problem less serious. Fire engines and police cars could replace those loud sirens(警报器) with other models; and you can turn down the volume inside your home by replacing noisy household appliances with quieter, energy-saving models.
“ I don’t think you can name a noise source that I can’t find a way to make quieter,” says Blomberg. But the real challenge is to change people’s attitudes. “ In the 1960s, we made it unacceptable to throw litter out of the window of your car,” he says. Today it’s time to recognize that “noise is to the soundscape as litter is to the landscape.” The goal is to “create a culture where you do not throw your aural (听觉的) litter out of the window.
