Abstract
The attenuation of fully developed, traveling, acoustic shock waves
was studied with particular emphasis placed on obtaining reproducible results
and extending the range of observation. High intensity sound waves
produced by a siren were propagated in a 5.4 cm radius tube treated to eliminate
reflection from the downstream end. After reaching a stable wave
form the decay of the acoustic shock wave was measured over a distance of
4.5 m by means of a traveling microphone. The frequencies used were between
610 and 1130 cps resulting in a ratio of wavelength to tube radius
of from 10 to 5. The pressure jump across the shock wave was from 1/35 to
1/8 atmosphere. Both of these ranges extend into previously uninvestigated
regions.
