This paper reports on calculations of the parameters of a bothsided perfo-rated sound-absorbing system, based on the "electric model" and considering the Rayleigh impedance. Both the absorption coefficient for perpendicular in-cidence and the reverberation coefficient over a broad frequency range were calculated.
