Specifically, snow tends to absorb higher frequencyacoustical waves.
特别的是雪倾向于保留高频的声波。
2
For a fixed sound source depth, the acoustical fields caused by high send frequency has strong sound intensity fluctuation, and their variation is sharp enough in an adjacent range.
对固定的声源深度，发射频率大的声场对应的声强起伏大，且相邻距离处起伏的强度很剧烈；
