1 > Perforated acoustic panel is a kind of resonance absorption material with holes through on the

      quality MDF board.

2 > It has strong selection on the sound spectrum and particular great performance on the middle

      and low frequency.

3 > If filled with the acoustic cotton at the back side space of the acoustic panel, it has better performance

      on the middle and high frequency.

4 >The holes diameter and pitch can be custom made.

5 > Strong impact resistance, excellent decorate performance, elegant color, especially work for wooden

      construction.

                                                                                                                                                                                                         Send inquiry soon>>

1 > The perforated 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 > Compared with the grooved acoustic panel, the perforated panel has better impact resistance.

4 > Our perforated acoustic panel’s highest fire retardant grade can reach A2(GB) grade, and the best

       environmental protection can reach E1(GB) grade.

                                                                                                                                                                                                         Send inquiry soon>>

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.
