摘要
本文对麻江型铜鼓进行了声学特性分析和其它有关项目的分析,我们发现麻江型铜鼓根据其基频和大小可分为两组,一组的基频在228—288Hz之间,另一组在340—412Hz之间,大多数麻江鼓的泛音都恰好是基音的倍频,这就是麻江鼓的声音特别悦耳的原因。麻江型铜鼓有雌雄之分。通过对雌雄铜鼓的考察和分析研究,搞清楚了它们的区别,其中公鼓的平均基频为350Hz左右,母鼓为280Hz左右。从而反映了中国古代南方民族已掌握了相当高的金属铸造技术。
Making a spectrum analysis and another analysis of Majiang drums, we found that they can be divided into two groups by their sizes and basic frequencies. The basic frequency of one group is between 228—288 Hz, and that of the other group is between 340—412 Hz. The overtone of most Majiang drums is coincidentally multiple of the basic frequency. This is the cause why the sound of Majiang drums is so melodious.
Why are Majiang drums divided into two groups? The existence of male and female bronze drums accounts for such a division. We have made an acoustic analysis and studied the distinction between male and female drums. According to the results of spectrum analysis, we conclude that male's average basic frequency is 385 Hz, female's is 280 Hz.
