ON THE PROPAGATION OF A WEAK PRESSURE WAVE AT VERY LOW PRESSURE.

Abstract

The propagation of a pressure-step discontinuity in an attenuating and dispersive medium is analyzed in the acoustic approximation. An exact solution is obtained, valid for all times and all distances. Approximate solutions for very short times and asymptotically large times are also presented. The range of validity of these approximations is indicated. The presence of an acoustic precursor signal, demonstrated by the exact solution only, appears to be a novel result. (Author)
