1A to 1E are illustrative views showing various resonance type mufflers that can be used in a muffler according to an embodiment of the present invention, FIG. 2 is a conceptual view showing an outline of an experimental device, and FIG. The figure is a graph showing the change in sound pressure level with and without a material that increases flow resistance in the same experimental apparatus. Figure 4 is a graph showing the change in sound pressure level in the same experimental apparatus with and without a material that increases flow resistance. Figure 5 is a graph plotting the sound pressure ratio on the inlet side and inlet side as a function of frequency. Figure 5 shows the outlet side sound pressure as a function of frequency when the flow path resistance coefficient of the material that increases the flow path resistance is varied. The plotted graph, FIG. 6, is a diagram corresponding to FIG. 1 showing a conventional muffling device. Explanation of symbols, 1... Piping line, 2... Resonance type silencer,
