摘　　要：对市场上常见的5种木质板材吸声系数进行了检测。结果表明:木质穿孔板在低频段、木丝板在中频段、轻质纤维板和木纤维/聚酯纤维复合板在中高频段,分别显示了优良的吸声性能,而刨花板的吸声性能较差。Sound absorption coefficient of particleboard,low-density fiberboard,wood wool board and wood fiber/polyester fiber composites were measured by an impedance tube instrument and sound absorption coefficient of a wood perforated plate was measured in a reverberation room.The results showed that sound absorption performance of the wood perforated plate was excellent at low frequency,the wood wool board had excellent absorption at mid frequency,the wood fiber/ polyester fiber composite and low-density fiberboard had excellent absorption at middle-high frequency while the partieleboard had very poor sound absorption at all frequencies.
