This paper addresses the comments of Dr. Bruggeman and Dr. van de Wetering. The source of the error present in the paper entitled "Linear inviscid wave propagation in a waveguide having a single boundary discontinuity: ...

The method of match asymptotic expansions MMAE, is used to analyze wave propagation in two problem geometries. The acoustic pressure is evaluated for a waveguide having a single discontinuity in wall slope and a waveguide ...

An examination of wave propagation in waveguides of rectangular cross section having a single boundary discontinuity is presented. Special attention is paid to waveguides with heights that are small compared to an acoustic ...
