基于声卡的合瓦形钟的“双音特性”研究

The Study "Double Sound Characteristics" of Hewa Shaped Bell Based Sound Card

针对合瓦形钟"一钟双音"的特殊声学现象,以麦克风作为声音采集装置,分别采集合瓦形钟的正、侧鼓位的声音信号,并用Matlab软件对其进行频谱分析。

For Hewa shaped bell ＂one-bell two-tone＂ special a caustic phenomena to the microphone as the sound collection devices,the positive and side of the drum bit sound signals were collected together,and the spectrum was analysed using MATLAB software.
