Science Museum Forest New Corner "Sound"

The new corner "Sound" opened on the 5th floor of the Science Museum Forest is an displays room where you can not only listen to sounds but also observe them with the eyes of science. Learn about the three major elements of sound (amplitude, frequency, and timbre) through various “waveforms” drawn by four experience devices: “Jumbo Piano,” “Laser Dance,” “Aqua Wave,” and “Cladni Pattern (relocated).” You can learn while playing. Among them, the "Jumbo Piano" is an interactive device that converts the waveform of the performance of a giant piano in real time and projects it on the screen, and is popular not only with children but also with a wide range of generations. In accordance with displays basic plan presented by the customer, we examined and produced the equipment, contents, and graphics to realize the image.

"Laser Dance" and "Aqua Wave" are devices that visualize waveforms by vibrating thin membranes and basins. Although it can be easily reproduced in a laboratory, it is a device that assumes unmanned, automated, and permanent installation. There were many challenges to clear, such as the durability of materials, maintenance of physical conditions such as tension, and specifications to maximize phenomena, and the degree of difficulty was high.
Also, the "jumbo piano" is a device where you step on the keyboard with your feet, and the major issue was how to extract the electric trigger while ensuring the durability and maintainability of the keyboard. It was a request to clear all preliminary experiments related to realization, and to drop it down to the dimensions and specifications that can be produced, and it was required to satisfy the visitors of the science museum.

In order to solve the above problems, the staff worked together to conduct all kinds of experiments. It was carried out in cooperation with partner companies, such as "selection and replacement method of thin film", "water supply method to water basin", "mirror shape for laser reflection", "optimal frequency for visualization", "durability test of materials", etc.
We also verified the operation interface by creating multiple demo screens that take into consideration the device characteristics and user psychology.
During the on-site period, windows were installed in temporary partitions to create expectations for visitors, and the construction was completed without any accidents, taking social good into consideration.
