的波长穿过冰有更快的速度旅行,和物理压力的大小变化导致声音不是100米。它更像是1米,所以这就类似于一个超大扬声器锥爆破空气波成冰,冰然后传送到麦克风的最明显的是在1 - 2米的深度。我能找到的最好的例证从风的压力差异和共振模式,大约5 - 15赫兹从这个1960的YouTube视频:https://youtu.be/TqTSyFz6DJc?t = 176扬声器锥的频率是由空气扰动冲击角的沙丘和雪风,产生1/2/3频率,也许从1/2/3不同的雪沙丘类型在同一地区,根据当地的沙丘形状,当暴风雨沙丘形状变化,相应的频率变化。[![在这里输入图像描述][1]][1]压缩雪吸收更高频率的弹性性质在深度和增加高浪在一起形成低波,所以冰的低频率的声音。不可能产生的频率是100米宽的横隔膜和压力差异,因为这会对应非常高的沙丘和长谷。高沙丘不太可能,和山谷风压力事件不会产生重大差异的压力。如果我是鲍勃moog,我想复制的物理共振过程沙丘,这将是一个相对容易的合成器设计。他们有地方低音音频锥在沙丘在不同的时间,不同的区域和测量频率和时间的3 d地图区域附近的人造声音发生器。 The unclear statements of the article say that: They measured Perturbation Velocity, a coefficient of flow dynamics for seizmology and of aerodynamics turbulance equations for physics? which kind of perturbation velocity is implied? Where are the equations for perturbation velocity and what a the name of the equations? Sound propagates through the firn layer, a study which may have already been measured and demonstrated by other snow and ice physicists? Sounds travel through snow, ice and water for different distances. To what distance and efficiency does firn transmit sound? there are graphs for snow acoustics and some of the research is hilarious: [one of the most complex pages of research i have ever seen][2] from this page: https://www.google.fr/search?q=sound+propagation+in+ice&num=100&source=lnms&tbm=isch&sa=X&ved=0ahUKEwjYptm3s5feAhVLOBoKHa2sBpEQ_AUIDigB&biw=1572&bih=808&dpr=1.5#imgrc=1z-RRNglm0UEGM: [1]: https://i.stack.imgur.com/KONZA.png [2]: http://rspa.royalsocietypublishing.org/content/471/2177/20140988
