The ratio of the sound pressure level at the exit to that at the entrance is minimized for a rectangular 2D straight lined duct of finite length carrying a uniform gas flow. The idea is to compute numerically this ratio for a large number of combinations of the values of the liner parameters (inertance, resistance, stiffness) and establish a formula for the dependence of the ratio on these parameters. Using this formula the minimum value of the ratio, as well the values of parameters, for which the minimum is obtained, are found numerically. [ABSTRACT FROM AUTHOR] |
