Abstract : The rate of attenuation of large-amplitude sound waves in the 30- to 200-c range was measured as a function of distance along a 10-in. -diam, 60-ft- long tube connected to a siren. The waves approximated a saw-toothed wave form. Expressions are developed for the attenuation caused by the tube walls and by the shock character of the wave. The effect of dc flow of air through the tube is evaluated.
