model description

        1Grooved wooden 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 wooden acoustic panel is made of high quality MDF board.

       2>  According to the customer’s acoustic and decoration requirement, our grooved wooden acoustic

             panel can equipped with outstanding environmental, flame retardant and waterproof function, even can

             with various colors and finish choices.

       3>  Our grooved wooden acoustic panel’s highest fire retardant grade can reach A2(GB) grade, and the

             best environmental protection can reach E1(GB) grade.

       4>  Grooved wooden acoustic panel structures’ finish including: Melamine, Natural veneer, Anti-fire plate,

             Paint, Metal sheet, Artificial veneer and leather etc.

       5>  Acoustic tissue including: The black color and attached at the back side of acoustic panel tissue, has fire

              retardant and sound absorption function.

Acoustic absorption is usually defined in terms of an absorption coefficient (usually denoted by the Greek letter alpha, α),

defined as the ratio of absorbed to incident sound energy from a single interaction between a sound wave and a certain

material.

Absorption coefficients range from 0 to 1 and vary with frequency,

    α=0 means that the material absorbs no sound and reflects all sound energy incident on it.

    α=1 means that the material absorbs all sound energy incident on it and reflects none.

Absorption coefficients of 0 and 1 are ideal values that do not exist in reality because all materials reflect and absorb some sound.

In general, materials having absorption coefficients less than 0.15 are considered to be reflective and those having absorption coefficients greater than 0.4 are considered to be absorptive.

As you can see our Testing report show that our products have a very good performance in a large range of application.
