Features:

1 Grooved 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

Application:
Broadcast station, TV station, library, theater, opera house, hotel, meeting room, computer machine room, researching lab, factory shop, gym, school etc. All these are in need of sound absorption material.
