On the Propagation of Sound Waves in Narrow Conduits Available to Purchase

The analysis of the propagation of sound waves in narrow tubes has usually been restricted to shapes yielding tractable mathematical expressions. A great number of practical applications do not fall within these categories and await a solution. An approximate solution of sufficient accuracy for narrow tubes of arbitrary shapes developed in this paper has been applied to a wire‐filled tube. The theoretical predictions check satisfactorily with the experimental results. It is believed that this study will be useful in other similar applications.
