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
