sound-pulse decay

In the measurement of random-incidence scattering coefficient by synchronized averaging of the impluse responses, the sound energy decay curve obtained by the backward integration of the squared averaged impulse will be influenced by the correlated components among these responses.

用脉冲响应同步平均法测量无规入射散射系数时，叠加后再经反向能量积分得到的声能衰减曲线，会受到不同脉冲响应中散射成分相关的影响。
