Acoustic panels are a commonly used new type of building material product in the modern construction industry, whose main function is to have sound-absorbing effect and ensure indoor quietness. At present, the types of sound-absorbing panels on the market are quite diverse, and the materials of different types of sound-absorbing panels are different. So, what is a sound-absorbing panel? What are the types of sound-absorbing panels? Do you know why sound-absorbing panels absorb sound? The use of sound-absorbing panels in our lives is very extensive, as they bring good news to those who need quietness. They have good sound absorption, sturdy structure, simple installation, long service life, and can bring peace to your ears. Choosing this material for decoration is a good choice. Let’s take a look at the relevant content introduction of sound-absorbing panels with me below!
One What is a sound-absorbing panel
Acoustic panel is an ideal sound-absorbing decorative material. It has the advantages of sound absorption, environmental protection, flame retardancy, thermal insulation, moisture resistance, mold resistance, easy dust removal, easy cutting, flower arrangement, easy construction, good stability, good impact resistance, good independence, high cost-effectiveness, etc. There are a variety of colors to choose from, which can meet the sound absorption decoration needs of different styles and levels.
II The sound absorption principle of sound-absorbing panels
1. The sound absorption principle of sound-absorbing panels is similar to that of snow covered panels. Sound-absorbing panels are mainly divided into micro porous and fiber types, and there is no essential difference between them. The sound absorption principle is to leave channels for sound to enter (channels composed of countless tiny holes connected together, or countless small gaps formed by fibers crossing and mixing together), but once the sound enters, it cannot come out. Due to the chaotic and long channels, the sound drills back and forth inside, impacts left and right, and gradually consumes energy in this process, playing a role in sound absorption.
2. All things with messy and long fine channels can be used for sound-absorbing purposes, such as cotton, various fiber uppers, cotton, sponges, carpets; But things like regular foam, egg cartons, and wooden boards have little sound-absorbing effect.
3. In addition, surfaces similar to needles are theoretically the best sound-absorbing materials. Acoustic laboratories are designed in this way. The principle is that after sound reaches the “needle” shaped surface, it continuously reflects inward and never reflects outward. This surface can completely absorb sound (and light) like a black hole, which is the “sound-absorbing wedge” used in soundproof chambers. However, this method is expensive, and generally recording studios and HIFI listening rooms do not require such thorough sound absorption, so they all use the materials from the front.
