A NUMERICAL SOLUTION FOR SOUND VELOCITY AND ABSORPTION IN CYLINDRICAL TUBES,

Abstract

A numerical solution of the Kirchhoff equation for the propagation constant of longitudinal sound waves in infinitely long cylindrical tubes has been obtained. The solution, which avoids the wide tube approximations, shows that the percentage errors in the Helmholtz-Kirchhoff tubevelocity correction and tube-absorption are both roughly equal to the percentage the velocity correction is of the free-space velocity.
