Voice Tube
★Exhibit Content: Interactive science popularization experience of sound wave propagation and duct waveguide acoustics principles ★Interaction: Multi-person manual acoustic interactive demonstration ★Operation: 1. Observe the multiple sets of curved pipe structures of the speaking tube, make sounds at the pipe ports, and listen by pressing your ear to the port; 2. Multiple groups interact by conversing at both ends of the pipes, experiencing sound clarity and sound wave transmission delay phenomena. ★Exhibit Description: The "Speaking Tube" is a large-scale interactive exhibit for science popularization of acoustic waves, belonging to the acoustics science exhibition area, and is a recommended exhibit by the PopsciCat Exhibit Store. The exhibit consists of a black metal vertical steel frame, multiple sets of independent colored sealed curved sound transmission pipes, and horn mouths for receiving and emitting sound at both ends. The pipes are arranged in spiral, folded multi-layer curved structures. When a visitor speaks into one end of the pipe, sound waves travel directionally through the sealed pipe to the other end, allowing clear conversation even over a long distance. This intuitively demonstrates the confinement and directional transmission effects of the pipe waveguide on sound waves. Multiple people can simultaneously conduct comparative group experiences, intuitively understanding the propagation laws of sound waves in a medium. ★Scientific Principle: Sound is a mechanical longitudinal wave that transmits energy through the vibration of medium molecules. In this exhibit, the air inside the sealed pipes forms a continuous sound transmission medium. The pipe walls continuously reflect sound waves, creating a waveguide effect that confines sound energy to travel along the pipe direction, greatly reducing the loss of sound waves spreading into the surrounding space. During transmission, only a small amount of energy is attenuated, and the main sound frequencies are fully preserved. At the receiving end, air molecules replicate the original vibrations, achieving clear long-distance sound transmission. The exhibit intuitively demonstrates the physical mechanisms of directional sound transmission in a sealed medium and fidelity sound transmission.
