sonic boom

音标发音

Breaking the sound barrier generates a sonic boom, so supersonic travel is heavily restricted over land.
打破音障時會産生音爆，所以超音速飛行在陸地上空有諸多限制。
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英尺高処的超音速飛機可以制造出50英裡左右寬的音爆圓錐。
Generally, the higher the aircraft, the greater the distance the shock wave must travel, reducing the intensity of the sonic boom.
一般，飛機飛得越高，沖擊波（到達地麪）所需要移動的距離就越大，使得音爆強度減弱。

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