We know the sounds of cities are loud enough to cause great harm to people`s hearing in the U.S. One person out of twenty has got some hearing loss. And all over the world the situation is getting worse and worse all the time since the noise increases with the population.With the development of machines, noise has also increased greatly in the 20th century. We live surrounded by loud planes, trucks and electric tools. TV sets and radios add up to 90 or J00 decibels, a certain unit used to measure the loudness of sound. A normal dialogue reaches 55 decibels; a plane goes to 100, and an ordinary train, reaching the station, can be twice as loud as the loudest plane. Disco music reaches about 118. At decibels the ear stops hearing sound, and pain starts. How terrible if things go on like this!眾所周知,在美國,城市巨大的噪音對人們的聽力造成了極大的損害。每20個人中就有一個有不同程度的聽力損傷。就世界范圍看來,因為噪音隨著人口的不斷增長,而越來越嚴(yán)重,這種情況也愈發(fā)惡化。瘋狂英語 英語語法 新概念英語 走遍美國 四級聽力 英語音標(biāo) 英語入門 發(fā)音 美語 四級 新東方 七年級 賴世雄 zero是什么意思菏澤市中富德林華府英語學(xué)習(xí)交流群
