Your response might be to imagine flying around in the dark, seeing the world in the echoes of high-frequency sounds.
对此，你的反应也许是想到：能在黑暗之中自由飞翔，籍由高频音波反射看清世界，如此等等。That prompted the invention of the " long range acoustic device" ( LRAD), designed to keep small boats away from warships.
这激起了「距离音波装置」设计来防止小船只接近战舰的发明。I all over shiver along with the sound wave and feebly loosen to open frog strange, the Wu lives ear and visits backward.
我随着音波浑身发抖，无力地松开青蛙怪，捂住耳朵，向后探望。NPC D: You do realize that you didn't actually cast a spell there? You just shouted the word "Sonic" loudly.
你知道刚才自己根本没有施法吗？你仅仅鬼叫了一声“音波”而已。NPC D: Sonic? SONIC? ? Curse you, elf, for finding the one energy form that I did not think to ward my children against!
音波？音波？？该死的，精灵。你居然挑中了一种我根本没考虑过给孩子们加护的能量类型！The equivalent of symmetry in aural cues is pitch, the frequency profile of a sound wave that makes a C note sound different from a G-flat.
听觉线索的类似对称是音高，这种音波频率使C调有别于降G调。Unlike the Sonic Emitter, the Shatterer has no minimum range.
和音波塔不同，震裂者没有最短射程。Keep a Sonic Emitter ready if he's flanking you with anything, either Stealth Tanks or Scorpions .
保持一个音波炮处于待发状态，以备对方部队（隐形坦克或者蝎子）从侧翼向您进攻。It also introduces the basic character of the pipelines signal and the basic theory of the acoustic measurement.
介绍了输气管道泄漏信号的基本特征和音波泄漏检测方法的基本原理。
