City noise never stops. The World Health Organization says that loud noises, like those from traffic or machines, can be a very harmful type of pollution. They can make people feel more stressed (有压力的), have trouble sleeping, and even cause heart problems. ①
City sounds are also making life difficult for some animals, for example, the funnel-weaving spiders (漏斗网蜘蛛).
② Funnel-weaving spiders make special webs that are not sticky (黏性的). They wait in their webs for bugs. Then, they quickly move to bite. To do this, the spider needs to feel the vibrations (震动) right away when an insect touches its web. But their webs often stick to things like trees, rocks and buildings. These objects act like highways that carry vibrations from environmental noise such as traffic. If there's too much noise around, it can be difficult for the spider to notice the insects.
③ Scientists notice city spiders making changes in their webs. The spiders adapt (适应) to noise by creating thicker webs with stronger silk and more connection points. Think of it like how we hang thick curtains (窗帘) to reduce traffic noise. Spiders just improve their webs instead! These designs act like natural noise-canceling headphones (降噪耳机), sending fewer vibrations to the spider. As a result, the spider can better feel the vibrations that really matter. ④
A team led by scientist Brandi Pessman at the University of Nebraska-Lincoln found out about this clever change. Their study helps us learn more about how animals deal with environmental noise. Humans might get better sound proofing (隔音) ideas from it too!
