| Abstract: | Methods to eliminate transfer matrix parameters of a straight tube and a rectangle anechoic elb-ow depending on the theory of sound waveguides are proposed. The main steps for analyzing high frequ-ency acoustical performance of a ventilation and sound insulation window by using transfer matrix meth-od are discussed. Sound insulation of a real ventilation window is calculated and measured,both in good agreement. |

| Keywords: | sound insulation window transfer matrix high frequency sound insulation |
