对水杯以敲击和吹两种方式发出的频率的区别,已经有不少文章了.笔者查阅了相关文章后,在参考的基础上进行了实验,得到的结论并不能与以往观点完全相同,从而尝试从不同角度对其做出解释.1工具选择为了使数据更易于采集,要求声波衰减系数小,频率调节范围大,于是笔者选择脚高8.5cm There are already many articles on the difference between the frequency of tapping and blowing in drinking cups. After consulting the relevant articles, the author conducted experiments on the basis of the reference, and the conclusions obtained are not exactly the same as those in the past. So try to explain it from different angles. 1 tool selection In order to make the data easier to collect, the acoustic attenuation coefficient is required to be small, and the frequency adjustment range is large, so the author chose to have a foot height of 8.5cm.
