摘要
The computational criteria used to judge the correctness of numerical calculation for sound propagationin ducts are presented.An improved finite-difference scheme is also obtained to solve the problem with thediscontinuity in the wall impedance.Moreover,a set of curves of numerical solutions compared withexperimental results for sound propagation in a practical hard-soft-hard wall duct and other samples arealso presented.The results show that the criteria and approach to discontinuity are successful and thatcomputational model is suitable.
