河北省张家口市2021届高三上学期英语期末考试试卷
Restaurants, schools, dentist offices are all keeping more windows open to let in more fresh air. Now researchers at Nanyang Technological University in Singapore have come up with a device that's like noise-cancelling headphones-but for a building.
It works on the same principle, so it detects noise that's coming into the windows and then cancels the noise. A microphone samples incoming noise, and then sends the speakers instructions on what sort of antinoise to give out. The result is to cancel out the incoming sound.
At the same time it allows air to keep flowing into and out of the window. The device is just a prototype—so it's still expensive. And it doesn't block out all sounds. It masks sound at frequencies from 300 to 1,000 Hz.
The technology will probably come in handy in Singapore as this country already has a lot of green buildings that use natural ventilation. But the downside is: when you have lots of openings in the buildings, the noise comes in. The group of window speakers could do the trick—especially if people prefer peace and quiet to a good view, which folks at home tend to do all night.
A. But this also lets in more noise.
B. The green buildings are energy-saving.
C. This includes the noise of freeways, trains and planes.
D. So you need some way to manage the increasing noise.
E. The headphones are designed for us to cover up our ears.
F. Compared with a closed window, the antinoise device is almost as good.
G. The device looks like a group of small speakers and fits over an open window.
