Polyester Fiber Grille Sound Insulation MDF Acoustic Wall Panel

1. Efficient sound absorption: full-band coverage and precise noise reduction
Outstanding absorption of mid- and high-frequency frequencies: The porous structure of the polyester fiber grille (aperture 5-30mm) significantly absorbs 500Hz-4000Hz human voice and high-frequency noise of equipment, and the sound absorption coefficient can reach 0.6-0.9, which can quickly attenuate indoor echoes (such as conference room speeches and classroom noise).
Composite structure enhances full-band performance: With the perforated or cavity design of the MDF substrate, it can cover the low frequency band (100-500Hz), such as absorbing the bass of musical instruments or the roar of movies and TV in the piano room or home theater to avoid "buzzing" residue.
Sound wave reflection control: The open grid of the grille reduces direct sound waves, and with the sound-absorbing cotton layer of the substrate, the indoor reverberation time can be controlled to 0.5-1.0 seconds (ideal office environment standard), improving language clarity.
