As you can imagine, sonic booms can be disruptive to life on the ground.

To understand how this might work, it's important to understand how a sonic boom happens.

要工作原理，必须先音爆是如何产生的。

When I heard a sonic boom for the first time, I finally understood why it was such a big deal.

当我第一次听到音爆的时候，我终于明白它为何如此重要。

But they've had to spend decades researching ways to fix issues with supersonic travel like a little thing called Sonic boom.

但是此前他们已经花数十年的时间来研究如何决超音速行的问题，比如一个叫做音爆的“小”问题。

But what exactly causes the sonic boom in the first place?

但是，究竟是什么导致音爆？

It's similar to a sonic boom but with light instead of sound.

它类似于音爆，但用的是光而不是声音。

As they reached Mach 2 the sonic booms could be heard throughout the desert below.

当他们达到2马赫时， 整个沙漠都可以听到音爆。

The air exited tunnels with a sonic boom that could be heard 400 meters away.

开隧道时会发出音爆， 400 米外都能听到。

It's designed to go supersonic without making the loud sonic boom, that -- that we've been accustomed to hearing for decades now.

它的设计目的是达到超音速，而不会产生巨大的音爆，我们已经听几十年。

Since a bullet moves faster than the speed of sound it creates a sonic boom.

由于子弹的移动速度比音速快， 因此会产生音爆。

When an object moves at supersonic speed, it generates a continuous moving shockwave known as a sonic boom.

当物体以超音速运动时，它会产生连续移动的冲击波，称为音爆。

This Sonic boom, an enormous amount of sound energy created when an aircraft breaks the sound barrier, which is about 750 miles per hour.

音爆指的是机突破音障时产生的巨大声能，时速约为 750 英里。

When they were retired in 2003 mainly due to unsustainable operational costs, and complaints about the thunderous sonic boom nothing took their place until now.

在2003年退休，主要是因为不可持续的运营成本，和乘客对雷鸣般的音爆的抱怨，它们一直无法被取代，直到现在。

This means that because of the laws of physics, a sonic boom will occur once the bullet passes Mach 1.

这意味着， 由于物理定律， 一旦子弹超过 1 马赫， 就会发生音爆。

The laws of physics will never allow a gun to be completely silent because of the sonic boom from the bullet.

物理定律永远不会让枪因为子弹的音爆而完全静音。

There is no way to stop the sonic boom of a bullet unless you can break the laws of physics.

除非你能打破物理定律，否则没有办法阻止子弹的音爆。

It flew over and even smash windows of skyscrapers as the famous sonic boom reverberated from the aircraft down to ground level.

当著名的音爆从机回荡到地面时，它过甚至砸碎摩天大楼的窗户。

The world below became a blur as I broke the sound barrier, the sonic boom echoing through the air like a symphony of thunder.

当我打破音障时，下面的世界变得模糊起来，音爆在中回荡，就像雷鸣般的交响乐。

The downside, supersonic travel creates a shock wave or sonic boom that is loud and disruptive over land, which is why it's only intended for long hauls across oceans.

不利的一面是，超音速行会产生一种冲击波或音潮，横跨陆地的时候声音会很响亮且具有破坏性，这就是为什么它只能适用于横跨海洋的长途旅行。
