探究钢管中声音节点的位置

Research in the Steel Pipe Sound Node Position

每根钢管都有一个声音节点,在此节点上固定钢管敲击时,就会发出特别清脆悦耳的声音。实验发现节点位置处于钢管长度的三分之一处,声音频率反比与钢管长度。空气柱与钢管的共振可以说明这个现象。

Each pipe has a sound node, the node on the fixed pipe percussion, will issue a special clear sweet voice. In this paper, for the same kind of materials with different length of pipe sound node posi- tion if there are common characteristics and on this node fixed steel percussion sound frequency rela- tion for doing the study, gives the experimental conclusion.
