A sonic boom is the thunder-like noise a person on the ground hears when an aircraft or other type of aerospace vehicle flies overhead faster than the speed of sound or supersonic.
音爆是当飞机或其它类型的飞行器以超音速飞过头顶时,地面上的人听到的类似雷声的噪音。
The lateral spreading of the sonic boom depends only upon altitude, speed and the atmosphere -- and is independent of the vehicle's shape, size, and weight.
音爆的横向伸展取决于高度、速度和大气,而跟飞行器的形状、大小和重量无关。
A sonic boom is the loud crash and shaking that happens when a jet plane goes faster than the speed of sound.
声爆是当喷气式飞机超音速行驶时产生的巨大碰撞和摇动声。
In this case, the 33 megajoules launched the shot 5,500 feet per second, exceeding the speed of sound and releasing a sonic boom.
如若这样,那么3千3百万焦耳发射出的炮弹速度高达每秒5500英尺,这一速度超越了音速,会产生音爆。

“sonic speed”是英语词组,中文译为声速(或音速),指声音在特定介质中传播的速度。以下是详细解释:
如需更完整的定义或应用案例,可参考声学相关权威资料(如、4、7)。
该单词由两个部分组成,sonic表示“音速的”,speed则表示“速度”。
sonic一般用来描述声音或者声波。例如:
speed通常用来描述物体运动的快慢。例如:
总之,sonic speed即为音速,是指物体在空气中传播时所达到的速度。
