Introduction to the Sound Concentrating Pavilion: In the "sound perception" area, there is a sound concentrating hall. The interior of the pavilion is a sphere. When visitors stand at a designated position in the center of the pavilion and make sounds, they can hear amplified sounds. The principle is that when a person speaks, the sound waves emitted will be reflected back when encountering obstacles in the propagation process. Since the person's head is exactly at the center of the sphere, the reflected sound waves gather here, and the echo and the sound emitted by the person are reflected. Mixed together, the original sound is strengthened and amplified, so a stronger sound can be heard.
