| Abstract: | The optimal method which takes sound absorbing energy of resonator in unit time as target function is proposed. Compared to the normal method that takes sound absorption coeficient as traget function, it can get better resonator's parameters. It also considers resonator perfomation nonlinear sound resistance and derivates approximate analytic solution of its relative sound resistance. |
