With the development of the urban economy and the increasingly serious noise pollution, people have higher and higher requirements for a quiet environment, so Acoustic Slat Wall Panel is used more and more in the decoration industry market. So by what principle does Acoustic Slat Wall Panel absorb sound? Here are some answers.
Here is the content list:
l The sound absorption principle of the Acoustic Slat Wall Panel is the same as that of the earth on a snowy night.
l Tips about Acoustic Slat Wall Panel.
Why is the land so peaceful on a snowy night? In classrooms, conference rooms, or music rooms, we often see Acoustic Slat Wall Panels installed on the walls, the purpose of which is to cut off the sound and prevent people outside from being disturbed. There are many small holes on the surface of the Acoustic Slat Wall Panel. When the sound enters the small holes, it will be randomly reflected in the inner wall, which is a bit like a sponge, until most of the energy of the sound wave is consumed and turned into heat energy, achieving the effect of sound insulation. . When it snows, the ground, buildings, and trees are often covered with a layer of snow. Unlike ice, snow is not a hard solid. On the contrary, snowflakes are sparsely aggregated and contain many small voids, a bit like the structure in the Acoustic Slat Wall Panel. These gaps have a sound absorption effect on sound waves, especially for sound waves with a frequency higher than 600 Hz.
This is the reason why the earth is extremely quiet on a snowy night. The sound-absorbing principle of the Acoustic Slat Wall Panel is also the same. The sound-absorbing materials are mainly divided into microporous types and fiber types, and there is no essential difference between them. The principle of sound absorption is to leave an accessible channel for sound (a channel composed of countless tiny holes that are connected, or countless fibers are crossed and mixed to form countless small gaps), but once the sound enters, it exits. Not coming, because the channel is too messy and too long, the sound burrows and slams into the left and right, and in the process gradually consumes energy, which plays a sound absorption role.
What needs to be reminded is that sounds of different frequencies are absorbed differently. High-frequency sound has a short wavelength and can be easily absorbed, while low-frequency sound has a long wavelength and can easily penetrate obstacles. For low-frequency sounds, it is not only difficult to insulate sound, but also difficult to absorb. It is not like high-frequency sounds that will bump into and out of cluttered small channels but will go around easily. But as long as you thicken the Acoustic Slat Wall Panel to a certain level, you can absorb low frequencies above 130Hz.
The above introduction is the sound absorption principle of the Acoustic Slat Wall Panel. The noise is always disturbing everyone around me. I hope it can help everyone.
