The amplitude taper and phase correction are obtained by redistributing energy and changing phase velocity in different region inside the horn respectively.
在喇叭内部不同区域中重新分配能量和改变相速来获得幅度锥削和相位校正。

The greater the amplitude change of head wave of transverse velocity is, the severer the damage is, the later the arriving time of the first wave hollow and the longer the damaged element will be.
Electrophysiological, there were sensory conduction velocity slowing, amplitude decrement of nerve action potentials, abnormal spontaneous activities and increased polyphonic motor unit potentials.
