Acoustic Ceiling Baffle

The Acoustic ceiling baffle is actually a porous sound-absorbing material, and its sound absorption characteristics are similar to those of other porous materials. When sound waves enter the material surface, they enter the tiny pores inside the material, causing the vibration of air molecules. The viscous resistance of the air continuously reflects and collides on the inner wall, and the sound energy is converted into heat energy to achieve the sound absorption effect; its sound absorption coefficient increases with the increase of frequency, and the high-frequency sound absorption coefficient is very large, leaving a cavity in the back and using it The formed space sound absorber can greatly improve the sound absorption performance of the material.

The noise reduction coefficient is about 0.8-1.0, making it a broadband high-efficiency sound absorber.
