Polyester fibre batten acoustic grille panels

Polyester fiber grating sound-absorbing panel is composed of sound-absorbing felt and spaced wooden strips, and is an excellent sound-absorbing diffusion material. Sound waves generate different reflected waves due to concave and convex surfaces, thereby forming the diffusion of sound; There are a large number of connected holes inside the sound-absorbing felt, and sound waves entering the holes generate friction and heat energy, effectively reducing echoes. The wooden grid sound-absorbing panel meets the dual acoustic requirements of sound absorption and diffusion with a beautiful and simple design.
