Produt Description:
 1> Grooved acoustic panel is a kind of slit resonance absorption  material which is made from high density
 panel with grooves on the surface and perforated holes at the back  side.
 2> It has strong selection on the sound spectrum and particular great  performance on the middle and low frequency.
 3> It has better sound absorption effect on medium and high frequency  if there is sound absorption cotton filled at the back side cavity..
 4> The design can be custom made
 5> How to calculate the perforated rate:
       1) When the hole line up in square P=0.785*(D/B)m2
       2) When the hole line up in Equilateral triangle
             P=0.907*(D/B)m2
        P ----- Perforated rate(%)
        D ----- Diameter of the hole
        B ----- Distance between two center of the holes


1>  The grooved acoustic panel is made of high quality MDF board.
2>  According to the customer?s acoustic and decoration requirement, our MDF board can equipped with outstanding environmental, flame retardant and waterproof function, even can with various colors and
finish choices.
3>  Our grooved acoustic panel?s highest fire retardant grade can reach A2(GB) grade, and the best environmental protection can reach E1(GB) grade.
4>  Grooved wood acoustic panel structures? finish including: Melamine, Natural veneer, Anti-fire plate, Paint, Metal sheet, Artificial veneer and leather etc.
