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.
