A sound muffler combines a resonator chamber with a dissipative layer surrounding a through pipe. The muffler provides sound attenuation over a wide range of sound frequencies while maintaining unimpeded flow of gases through the pipe. This attenuation is achieved by combining dissipation with a frusto-conical resonant chamber. The dissipation is achieved by encircling the through passage with a layer of low density material such as metallic or ceramic foam or loosely packed fibers of a heat resistant material. The low density material attenuates the high frequency waves while permitting the passage of low frequency sound waves into the frusto-conical resonant chamber.
