RESEARCH ON UTILIZING SOUND ATTENUATION BAFFLE CONTROL RADIATION OF SOUND IN THE VENTILATION DUCT TUYERE OF AIR SUPPLY AND AIR RETURN
【摘要】 根据扁矩形消声通道二维消声理论替代一维理论导出的消声系数Φ(α),研究了障板消声结构的Φ(α)计算机程序和消声量与障板几何尺寸的关系
【Abstract】 This paper according to normal rectanglar duct sound Attenuation Loss Passage 2- D Sound Transmission Theory instead of Sound Deadening Coefficient Φ(α)from 1-D theory deduce, gives Computer Program of the instruction of Sound baffle’s sound deadening coefficient Φ(α) and the relationship of the guantity of sound transmission Loss and sound baffle’s geometrical size.
