When a wave travels uniformly in all directions from a small source, the intensity varies inversely as the square of the distance.
当波从小扰动源向各个方向均匀传播时，其强度的变化与距离的平方成反比。
Some maneuvers — pushovers, acceleration and "s" turns — can amplify the intensity of the shock wave.
一些飞行动作——拉升、加速和S型转弯——会增大冲击波的强度。
Generally, the higher the aircraft, the greater the distance the shock wave must travel, reducing the intensity of the sonic boom.
一般，飞机飞得越高，冲击波(到达地面)所需要移动的距离就越大，使得音爆强度减弱。
