Many people have a certain misconception about sound-absorbing panels, thinking that only places like KTVs or cinemas require sound-absorbing panels. In fact, as a decorative and functional material, sound-absorbing panels have been applied in every aspect of our lives. In addition to KTVs and cinemas, sound-absorbing panels are also installed in schools, hospitals, shopping malls, office buildings, clubs, hotels, gyms, theaters, and even in many people's homes.

Why are sound-absorbing boards so widely used?

We can understand from the material itself. A sound-absorbing board refers to a board shaped material that has the function of absorbing sound and reducing noise. Today, we mainly talk about wooden sound-absorbing boards. Wooden sound-absorbing boards are exquisitely processed based on acoustic principles and are composed of finishes, core materials, and sound-absorbing thin felt.

Wooden sound-absorbing boards are divided into two types: grooved wood sound-absorbing boards and perforated wood sound-absorbing boards. Grooved wood sound-absorbing boards are a type of resonant sound-absorbing material with slots on the front and perforations on the back of density boards; Commonly used for wall and ceiling decoration

Sound propagates in the air, and when it encounters obstacles, it will reflect and produce reverberation. If there is echo, the indoor sound will be relatively blurry. Especially in some relatively large public indoor places, such as service halls, waiting rooms, offices, cinemas, etc., the reverberation and noise generated are greater; In such an environment, if sound-absorbing materials are not installed, even face-to-face chatting may sound very difficult.

The main function of a sound-absorbing board is to "absorb sound". There are many small holes on the surface of the sound-absorbing board. After the sound enters these holes, it will randomly reflect in the inner wall of the structure, which is somewhat like a sponge, until most of the energy of the sound waves is consumed. This way, there will be no reverberation or echo, and the sound will sound clearer and more accurate.
