A sonic boom is a sound associated with shock waves created when an object travels through the air faster than the speed of sound.
物体以超音速划过大气时,所产生的冲击波带来的声响形成音爆。
A sonic boom does not occur only at the moment an object crosses the sound barrier and neither is it heard in all directions emanating from the supersonic object.
音爆不止发生在物体穿越音障的时候。人们也无法在各个方向上都能听到物体以超音速穿越大气时发出的音爆。
