Previous research on acoustic scattering was generally on the premise that the incident waves were plane waves.

声散射问题的研究一般建立在入射波为平面波的基础上。

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.
