这是来自沪江的一篇英语科技文~~非常有趣。。。
我们都说看到彗星划过天空，可是我们能听到它划过的声音吗？
最近前几天，英仙座流星雨爆发，可惜正逢月满中天，皎洁的月光暗淡了流星的光彩。。。
不过据说呢，在2001年英仙座流星雨喷发时，很多天文爱好者“听”到了彗星的声音。
不过科学家并不以为然，根据光速和声速的差值，当我们看到彗星滑落的十分钟后才能
真正听到他们的声音，如果能传得到的话。
但是天文爱好者却坚称他们听见了类似炸培根时的“咝咝”声？
这是怎么回事呢？
日前，澳大利亚的Newcastle的Colin博士则从另一个角度解释了这一现象。
他称，在彗星会发射低U频率的无线电，这种无线电传播的速度与光相当，
虽然它本身的声音人是听不到的，但是他发射的声波会导致地面的物体发生共振，
而人的耳朵正在加入了这场运动之中。
因此，我们听到的“咝咝”声，是耳朵某部位发出的。
如同我们将海螺套在耳边时，听到大海澎湃的声音，
那不是大海，是我们的血液和身体在嘶喊，
海螺由于其光滑的曲面，反射了我们体内的声音。。

During the 2001 Leonid meteor storm, a number of people reported hearing meteors. Some exceptionally bright meteors were said to have been accompanied by a low hissing sound - like bacon sizzling.
These meteors are called ‘electrophonic' meteors by astronomers , they're seen and heard simultaneously. Many astronomers tend to dismiss these reports as fiction. Typically, a meteor burns up about 100 kilometers - or 60 miles - above the Earth's surface. Because sound travels so much more slowly than light does, the rumblings of a particularly large meteor shouldn't be heard for several minutes after the meteor's sighting.
But according to Dr. Colin Kaey at the University of Newcastle in Australia, electrophonic meteors are real. Kaey explains that meteors give off very low frequency radio which travel at the speed of light. Even though you can't directly hear radio waves, these waves can cause physical objects on the Earth's surface to vibrate. The radio waves cause a sound - which our ears might interpret as the sizzle of a meteor shooting by.
