Where is the largest sound bar in the world???

The world's largest natural sound wall listed in the Guinness Book of Records is actually in China! Zhangshiyan, located in Zanhuang County, Shijiazhuang City, Hebei Province, is 400 kilometers away from Beijing, and is the most majestic and beautiful section of Taihang Mountain.

Zhangshiyan, a national scenic spot, is located in Zanhuang County in the southwest of Shijiazhuang (52 kilometers to Zanhuang County), about 110 kilometers away from Shijiazhuang, the capital of Hebei Province, and is the essence of Taihang Mountain Forest Park. Its highlight is the large natural echo wall. The scenic area is about 120 square kilometers, standing at the highest point of the scenic spot, Huang'an Yuan (1774 meters above sea level), you can see two provinces and five counties.

The landform of the whole tourist area has been identified as "Zhangshiyan landform" by the national tourism and geological departments. The Zhangshiyan landform named after Zhangshiyan, together with the Danxia landform and the Zhangjiajie landform, is known as the three major tourist sandstone landforms in China.

The landscape of Zhangshiyan is mainly "Danya, Biling, strange peaks, and hidden valleys". Its landscape characteristics can be roughly summarized as "three stacks with nine sets, four screens and eight scenes". Three stacks are three ancient roads; Nine sets are nine valleys that connect three ancient roads; The four screens are the four sub-scenic areas that seem to be the same as the four barriers as a whole and are relatively independent (Nine Female Peak, Yuantong Temple, Paper Paste Cover, and Frozen Ling Back).

There are eight famous scenic spots in these four scenic spots: Nine Immortals Gathering, Rock Banhua Palace, Raining on a Sunny Day, Echoing Giant Cliff, Huaiquan Coolness, Frozen Ling Jade Pillar, Heavy Door Lock Cui, and Stacked Hanging Bells. There are paths connecting these three stacks, four screens, and eight scenic spots, and nine sets, and 120 scenic spots are interspersed.

Among them, the natural echo wall, the frozen Ling jade pillar, the fog cave, and the Buddha light are the "four uniques of Zhangyan"; Rainfall on a sunny day, stone milk spirit spring, cloud cliff beads, silver waterfall falling lake are the four unique waterscapes of Zhangyan again. The majestic Zhangyan three stacks, the Qixiu Nine Female Peaks are breathtaking; A string of natural attractions such as the first-line sky, Sanxiu Gorge, Huaiquanyu, Ruquan Cave, and the Great Heavenly Ladder are fascinating. The thousand-year-old temple Huaiquan Temple, the Jade Emperor Temple and the Thousand Buddha Monument of the Three Stacks of Shengjing, the Dawangtai, the Yijun Village and other cultural landscapes are good places to explore the ancient world.

The natural ecology of Zhangshiyan is good, and the foothills and stack tops are covered by trees, shrubs, vines and grasses. With a total of 654 species of plants in 98 families, it is the "natural botanical garden" with the best protection and the most complete varieties in North China. In spring, mountain peach blossoms, rhododendrons, lilacs, roses, shandans, and meadowsweets are all over the slopes, and the stamen is in full bloom; In the middle of summer, it is lush and green, flowing springs and waterfalls everywhere, the sea of clouds and the Buddha's light are strange and magnificent; In autumn, the forests are dyed, colorful, and in full swing; In winter, the fog pine trees hang, the jade Keqiong branches, and the icicles are optimus.

In the Temple of Heaven. The echo wall is the wall of the imperial dome, with a height of meters, a thickness of meters, a diameter of meters, and a circumference of meters.

The world's largest echo wall is in Hebei, more than 90 meters high and 300 meters long, and it is ring-shaped. According to the data, the echo wall of Wuchuan is the longest echo wall in the world, with a length of more than 600 meters. Hebei's sound wall has been awarded the Guinness World Records certificate.

Wuchuan should apply as soon as possible, and it is believed that he can obtain the Guinness certificate.

The world's largest echo wall is in the heart of Sissy

The Echo Wall is the wall of the Imperial Dome. The sound bar has an echo effect. If one person stands under the wall of the east side hall and whispers to the north wall, and the other person stands under the wall of the west side hall and speaks softly to the north wall, the two people can clearly hear the voice of the other person at the other end of the distance, and the voice of the voice echoes for a long time.

It creates a mysterious atmosphere of "heaven and man induction".

How did the magical sound bar come about? Was it deliberately designed by the ancients, or was it a coincidence.

Sound bar. It is a circular wall that surrounds the imperial dome, with a height of about 6 meters and a circular radius of about one meter. There are 3 buildings inside, one of which is the circular Imperial Dome, located in the middle of the north face, and its closest point to the enclosure wall is only one meter.

The Echo Wall has only one door, facing the Imperial Dome. The entire wall is neatly built and smooth, making it a good sound reflector.

If A and B are far apart, and A is close to the wall and whispers to the wall, B can hear it very clearly when he is close to the wall, and the sound seems to come from B's vicinity. If the nail makes a sound tangent with the point of the a.

When the angle is greater than 22 degrees, the sound will be reflected elsewhere when it touches the imperial dome, and B will not be able to hear clearly or inaudible.

Beijing's Temple of Heaven is world-famous for its majestic architecture, and attracts visitors with its amazing echo wall and three-tone stone. Anyone who has been to the Temple of Heaven will be amazed by its wonderful sound transmission phenomenon.

We know that when we usually speak, we can't hear clearly when we are five or six meters apart. And standing on one side of the wall of the Temple of Heaven Echo Wall to speak softly, the people on the other side of the wall can also hear it clearly, and there are more than 50 meters between them! The strange thing is that if you stand on the sound stone in the center of the sound wall and clap your hands, you can hear two or three consecutive clappings.

How did the magical sound bar come about? Was it deliberately designed by the ancients, or was it a coincidence.

The reason why the sound wall transmits sound effects over long distances is that the walls of the Imperial Dome are conducive to the propagation of sound waves. The fence wall is made of ground bricks with joints, smooth and flat, which basically conforms to the boundary conditions of the wave equation of the defeated elastomer on the surface, and can easily receive the sound waves close to the wall. Sound waves propagate through walls, i.e. in solids, faster than in air, and produce less energy loss, which explains the phenomenon of audible sounds.

In the process of sound wave propagation, the penetration depth of the wave with a small frequency is large, and the loss is also large, which effectively filters the low-frequency noise and causes the sound to be long.

The Echo Wall is the wall of the Imperial Dome. The wall is meters high, thick, diameter, and perimeter. The walls are made of ground bricks and are covered with blue glazed tiles.

The curvature of the wall is very regular, and the wall surface is extremely smooth and neat, which is very conducive to the propagation of sound waves. As long as two people stand behind the east and west side halls, standing against the wall, and one person leaning against the wall to speak to the north, the sound waves will be transmitted along the wall in the form of sound waves.

At the other end of the first and two hundred meters, no matter how small the voice is, it can also make the other party hear it clearly, and the voice is long, which can be called interesting, creating a mysterious atmosphere of "heaven and man induction". Because it was mistaken for an echo formed by the reflection of sound waves, it is commonly known as the "echo wall".

The magic of the echo wall is that if two people stand behind the east and west side halls against the wall, although they can't see each other, they can talk to the wall, and they can clearly hear each other's voices. This is due to the fact that the sound is reflected many times on the fence and "crawls the waiter" to the other person's ear.
