The reflected pressure of the fluid is similar between the plane acoustic wave and the point source acoustic wave.

因此，这两种不同入射声波的声波反射压力的变化既有不同，又有着相似之处。

Early ideas suggested blunting the nose of the plane to prevent the pressure waves joining up to form one intense shock wave, or lengthening the plane without increasing its weight to dampen the noise.
