Echo Wall

This is a scenic spot in Beijing Temple of Heaven Park. When I went there in the early years, I could hear the effect of echoes. Now it is damaged by some buildings! I really don't know if it is protecting. [View] Unlike in the past, [Fun] Can't find the echo of the year, [Cost-effective] set up small attractions, second ticket sales! This trip is to play with grandsons, and there is a sense of history!

There are more people here, and the walls of the echo wall have been protected by railings. It is not very smooth to touch it by hand. The thousand-year-old city wall has been baptized by the wind and rain, and it has been very old and vicissitudes.

The echo wall of the Temple of Heaven is the round wall of Huang Xuyu, high 3.72 meters, thick 0.9 meters, circumference 193.2 meters, the wall is made of grinding bricks against the seams, the wall is covered with blue glazed tiles, and the fence is now protected under the wall. Visitors to this tour generally have to stick to the wall to try the echo wall echo, but there is no effect.

The echo wall is located in the Temple of Heaven Park. It is a circular wall of Huangxuanyu. The wall is slitted with Shandong Linqing bricks and is covered with blue glazed tube tiles. Because the arc of the wall is very regular, it becomes a good reflection body of sound waves. Two people stand at both ends of the wall and can hear the sound. The two people responded, one question and one answer, and the voice was long, which was strange. Feel the wisdom and magic of the ancients.

The echo wall is the round wall of the imperial palace, because the wall brick grinding bricks to the seam, extremely smooth, so become an excellent sound wave reflection body, it is said that two people stand in the east and west of the hall dialogue, the sound can be extended to the round wall effectively spread, both sides can talk freely. Many people test this echo function on the spot, and I don't know how the actual effect is. Anyway, if there are more people, the reflection effect is no better, and I can't hear it clearly. If you wait for a special clean time to try it, it is estimated that the effect can be good.
