This exploration is inspired by a famous experiment performed by the German physicist and musician, Ernst Florens Friedrich Chladni. He lived from 1756 to 1827 and is called the father of Acoustics because of his work on vibrating plates. He demonstrated the visualization of the nodal lines by sprinkling a layer of powder onto the surface of the vibrating plate. These observed patterns are called Chladni patterns.
This research is based on state-of-the-art theory to develop software for virtually emulating the nodal lines of a vibrating plate. The main aim is to provide a digital and open-source platform to assist students in learning the resonance phenomena of a vibrating plate. By using the developed platform, students can dynamically visualize the nodal-line formation of a vibrating plate without physical equipment. Since the developed simulator can be operated anytime and anywhere with a personal computer, it can greatly reduce the time required for the physical experiment. Furthermore, the dynamic visualization technology makes the educational process more convenient, expands the number of participants, and deepens the understanding of physical insights. The developed platform can be used in classrooms as well as informal places. Consequently, enables lifelong learning for anyone, makes physics education more diverse and inclusive, makes scientific education more diverse and interesting, and especially reduces educational gaps between urban and rural regions, and makes education more equitable for the general public, as well as enhances access to physics knowledge and digital education.
Since traditional Chladni plate resonance experiments often require a large amount of materials and complex equipment that are not available to every region or student, this research developed simulation software to solve the problem of difficult access to resources. Compared with existing similar works in the world (such as ShaderToy, and thelig.ht Chladni experiment), the simulation software developed in this research can provide users with a learning environment of interactivity and diversity. Through advanced audio processing technology, this simulator can produce a sense of presence, especially the realism of the sand movement and the resonant sound. Users can freely adjust the parameters of the experiment to observe and experience the realistic changes. Moreover, the developed simulator also provides users with the functions of image and data storage for further numerical analyses and scientific investigations, and then learn the principles of physics in depth. T
o sum up, the digital simulation tool developed in this research not only reduces the complexity of the experiments but also provides the functionality for distance education. The open-source nature of the simulator allows users to further customize this software according to their teaching and experiential needs, thereby making more contributions and sharing it for the education field.
