Research on Influence Factors of Absorption Performance for Wooden Perforated Panels

摘要：

Standing wave tube was used to test the sound absorption abilities and analyze the influence factors of perforated medium density fiberboard (MDF).The test results show that bore diameter,perforated rate and different depth of space from the structure are the key factors influencing the absorption performance of wooden perforated panels,but decorative facing and bore shape have a little contribution to absorption abilities.Research finds that absorption peak will move towards high-frequency with decreasing the bore diameter so as to increase absorption effect in high-frequency,and excellent high-frequency absorption performance can be achieved by increasing perforated rate.On the other hand,larger depth of space from the structure will raise the absorption abilities in low-frequency of the panel.
