Perforated wood sound absorption board classification:
1.Big and small perforation:Mainly to meet the low-frequency sound-absorbing requirements, for low frequency sound absorption is based on the combination of small holes on the visible side and the big holes on the back side. Small perforated surface makes the decorative effect of the wall more beautiful.
2.Straight perforation:Mainly meet the sound absorption requirements for medium and high frequency. Sound absorption is mainly determined by the perforation rate, it is also affected by the size of the cavity between the acoustic material and the wall or ceiling.
3.Reflective surface:This structure can also be used as a reflector, its characteristic is that the back is not perforated. The acoustic function is equivalent to a standard reflector.
