Research on the Characteristics and Double-Tone Rules of Chu-Han Chime Bells

In order to explore the acoustic characteristics of chimes and the law of double tones, this paper takes the Chu and Han dynasties (206~202 BC) in this paper, Chimes are used as an example for analysis. Firstly, the characteristics of Chu and Han chimes were collected, the chimes were classified, and their materials and production techniques were studied. Then, the electronic scanner was used to observe the surface of the chime, and the acoustic test software was used to analyze the law of the two tones and draw the sound principle of the chime. The results show that the chimes of the Chu and Han dynasties are mainly shaped with wide mouths and uniform hanging methods, and the chimes are mainly made of bronze, tin and iron, so the pitch is higher. The spacing between chimes varies depending on the shape and size, so it is easy to resonate. In addition, there is a resonance gap between the main drum and the left and right drums of the chime, which prolongs the sound propagation distance of the chime. Therefore, the Chu-Han chime is the culmination of Chinese chime technology, and its acoustic characteristics are reasonable, forming a resonance between the main drum and the left and right drums, and forming a resonance between the chimes, realizing two-way sound, which has an enlightening effect on modern music teaching.
