| Abstract: | A declining noise model for infinite long barrier to line sound source is made in terms of the function of insertion loss for barrier to point source in GB/T17247.2-1998.And a program is programmed for a special problem in MATLAB in this article.It is certified that the model and program are all correct and feasible by the comparison between calculating consequence and practiced measuring consequence and the comparison between calculating consequence and Meakawa curve. |

| Keywords: | barrier point sound source line sound source sound pressure level Frenel number insertion loss |
