摘要
每个人都知道，耳朵是用来听的。但一项新的研究发现，对于一种叫做鹅嘴鲸的生物来说，听的过程是从喉咙里开始的。研究人员说，进行观察可能有助于解释鲸鱼是怎样听的。这项研究有可能帮助科学家弄懂水下声呐对动物的影响。声呐在技术上与雷达相似，有些船只使用声呐，通过发射声波的方法探测并确定水下物体的具体位置。
Ears are for hearing-everyone knows that. But for a creature called the Cuvier＇s beaked whale, hearing starts in the throat, a new study finds. The observation might help explain how all whales hear, researchers say. The work might also help scientists understand how animals are affected by underwater sonar. This radar-like technology, used by some ships, sends out sound waves to detect and locate underwater objects.
