Science Museum Forest New Corner "Sound"

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