Decorative Acoustic Panels

Sound originates from the vibration generated by the object, which causes the vibration of the adjacent air to form sound waves, which propagate around in the air medium. For example, in places such as churches and conference halls, it is necessary to concentrate the sound, eliminate echoes, and the speaker's voice is three-dimensional and clear, so that the audience can hear the content of the speech more clearly. Decorative Acoustic Panels are often used in types of places, and the response effect is also excellent.

We cannot give specific data on the efficacy of Decorative Acoustic Panels, because the area of the use site determines the sound-absorbing coefficient of the Decorative Acoustic Panels. According to the structure of the whole space, the characteristic of sound is that the reflection is weakened in the whole space. If the area of the sound-absorbing panel is increased, the sound wave can be quickly converted into heat energy, thereby eliminating the echo.

The internal structure of sound-absorbing materials is mostly loose and porous. The principle is that sound waves enter the pores of the material, and the pores are open holes that pass through each other. The sound waves are subjected to molecular friction and other resistances, causing the fine fibers to mechanically vibrate, and the sound energy is converted into heat energy. . The sound absorption coefficient of the porous Decorative Acoustic Panels changes according to the change of the site area, and generally increases gradually from low frequency to high frequency, so it has advantages for sound absorption effect of medium and high frequency.
