喷流被用来大致模拟大气湍流的局部区域，模拟一个单一的理想化的“涡流”。射流被布置在UTIAS 80英尺音爆发生器喇叭中，以便对着音爆传播方向或与音爆传播方向一起吹。这两种情况分别产生了尖峰和圆形的爆炸声特征，定性上与理论雅阁。与湍流大气条件下超音速飞行产生的信号相似，特别是以尖峰“超级繁荣”为标志。
A jet flow was used to model roughly a localized region of atmospheric turbulence, simulating a single idealized “eddy.” The jet was arranged in the UTIAS 80‐ft sonic‐boom generator horn so as to blow either against or with the direction of boom propagation. The two cases produced spiked and rounded boom signatures, respectively, qualitatively in accord with theory. The resemblance to signatures resulting from supersonic flight under turbulent atmospheric conditions was especially marked with the spiked “superbooms.”
