Abstract: The invention discloses a prediction method for porous material of electroacoustic devices and prediction system thereof. The method comprises the following steps. The step (A) is to obtain at least one acoustic parameter of a porous material from an electroacoustic device, and the at least one acoustic parameter comprises a flow resistance value, a specific flow resistance value and a flow resistance ratio. The step (B) is to calculate an actual resistance value of the porous material based on the at least one acoustic parameter. Thereafter, the step (C) establishes an equivalent circuit model corresponding to the electroacoustic device based on the structure configuration and material parameters of the electroacoustic device. At last, step (D) introduces the actual impedance value of the porous material into the equivalent circuit model, and calculates the frequency response curve and impedance curve of the electroacoustic device affected by the porous material.
