1.And we placed infrasonic microphones around the elephants as we did these experiments.

在进行些实验时，我们把次声传声器放置在大周围。

2.Elephants do that. Rhinos do that. Hippos do that. Crocodiles do that. Alligators do it. They produce infrasound.

大用次声交流，犀牛也。还有河马，鳄鱼，短吻鳄。它们都发出次声波。

3.Elephants, for example, talk with each other using infrasound– far below our human hearing range.

大用远低于人类听觉范围的次声波唠嗑。

4.It's possible you could have actually died from the sound wave impacting and smashing through your body.

你甚至可死于次声波对你的冲击和粉碎。

5.At the other end, in the deep infrasound, elephants and whales, tigers and some birds make sound.

另一端的低频次声，大、鲸鱼、老虎和一些鸟类制造样的声音。

6.But even if you didn't, you would be guaranteed to be permanently deaf for life afterwards.

但即使你幸免于难，次声波也你后半生终身失聪。

7.But this peacock is also making very loud infrasound with its tail, which you cannot hear, but female peahens can.

但只孔雀与此同时也在用它的尾巴制造次声巨响，你是听不到的，但雌性孔雀可以听见。

8.Anything below that is called infrasound.

低于此的任何东西都称为次声。机翻

9.So, that is how elephants use infrasound.

好了，是大使用次声波的方式。

10.But it travels even further through the earth as infrasonic rumbles.

但随着次声波的隆隆声，它在地球上传播得更远。机翻

11.These are extremely low sounds that we humans are unable to hear, but fans, wind turbines and traffic can produce them.

次声波的频率非常低，我们人类无法听到，但是它产生于风扇，风轮机和交通工具。

12.The system, the firm claims, produces frequencies from infrasonic to ultrasonic that are " essentially capable of effectively simulating any ship" .

该公司声称，该系统产生从次声波到超声波的频率，“基本上够有效地模拟任何船只”。机翻

13.Hidden sounds, because much acoustic communication in nature occurs in the high ultrasound, above your hearing range, or in the deep infrasound, below your hearing range.

隐秘声音，是因为自然界中很多声音的交流都在高频超声的频段，超过了你的听觉范围，或是在低频次声的频段，低于你的听觉范围。

14.And it turns out they're communicating to each other in infrasonic rumbles to warn each other of the threat of bees and to stay away from the area.

后来发现它们在次声波段隆隆低语地交流来警告彼此蜜蜂的威胁并且远离蜜蜂所在区域。
