ATTENUATION OF REPEATED SPHERICAL SHOCK WAVES,

Abstract

When finite amplitude sinusoidal waves travel in the air, stable shock waves are produced. These shock fronts of abrupt pressure change are caused by the non-linearity of the medium. The object of this experiment is to determine the excess attenuation of weak shock waves over the inverse square law and to compare the results with theory. The sound source was a siren and fundamental fre quencies between 8.5 kc and 11 kc were used. The experiment was performed in an anechoic chamber. By correcting for an effective source position, the experimental results were brought into good agreement with the theory. (Author)
