sonic boom

音标发音

Breaking the sound barrier generates a sonic boom, so supersonic travel is heavily restricted over land.
打破音障时会产生音爆，所以超音速飞行在陆地上空有诸多限制。
An aircraft, for example, flying supersonic at 50,000 feet can produce a sonic boom cone about 50 miles wide.
例如，一架50,000英尺高处的超音速飞机可以制造出50英里左右宽的音爆圆锥。
Generally, the higher the aircraft, the greater the distance the shock wave must travel, reducing the intensity of the sonic boom.
一般，飞机飞得越高，冲击波（到达地面）所需要移动的距离就越大，使得音爆强度减弱。

Of course, we all know that there is one little problem with super-sonic flight: the sonic boom.
